- Scientists Discover Planets More Habitable Than Earth
► Subscribe: goo.gl/r5jd1F
Just about 30 years ago, we didn’t have any scientific proof of a planet outside our solar system. Today, thanks to advances in technology and scientific research, we've discovered over 5,300 exoplanets - alien worlds that are out there waiting to be explored.
At first, these discoveries mostly involved large gas giants, but as our capabilities have expanded, we've started to uncover smaller, Earth-like exoplanets. Scientists have already found more than 50 exoplanets with masses similar to Earth, and over 800 worlds with radius less than one half times that of Earth.
We don’t know of many such planets orbiting in the habitable zone of their parent stars - where the conditions are just right to support life. But that's already starting to change.
As our search for habitable planets continues, we're beginning to discover entire planetary systems with more than one potentially habitable world. And we already know about at least one such system in our cosmic neighborhood.

Crazy we're able to confidently describe planets that are lightyears away, yet we don't even know what lurks in the deepest parts of our own oceans.
tbh It makes perfect sense. You can use a telescope to see though the vacuum of space, but you can't do the same with the ocean, you actually have to go and explore it all inch by inch and building things that can withstand the pressure at the bottom of the ocean is incredibly difficult.
I don't think the word "confidently" is the word I'd use. Lot's of "possibilities" and "uncertains" thrown in there. They don't really know.
@@manoadamro1768 They aren't sure about any of it. An alien civilization could look at our solar system from afar and surmise that Venus and Mars are "possibly" habitable because they're in the "goldilocks zone", but we all know they aren't.
@@manoadamro1768that's not how that works. They analyze the light from the planets star that comes through its atmosphere because different compounds will absorb different wavelengths of light.
We know all we need to about the oceans. That’s just a thing people say, that we don’t , because it sounds interesting and thoughtful. It’s also a thing people who want grant money say.
Imagine living in a solar system where there's 4 habitable planets and people travel between them on holiday or immigrate from one to another for a better life
. . . and they're stupid enough to go to war with each other on all of them!
Well, if there's immigration, I say build a wall between them.
That would be neat, eh. I often wonder about those sorts of things myself. One day I s'pose but when that time comes we'd have been pushing up daisies for a good while! But hey ho, it's still a nice thought all the same.
pretty sure there would be piracy and war
It would just means 4 more planets for human to pollute and destroy
Crazy thing to me is that we’re seeing these planets that are millions of light years away. Meaning that were seeing them from a million years before the time it actually is. For all we know, now they could be red fiery planets.
ahahahah. totally by the time we reach there its a fireball
No hundreds or thousands of trillions of kms is not millions of light years
Our entire galaxy is about 100,000ly across. We are not seeing planets millions of light years away as that would be far far beyond our current technical capabilities.
1 light year = six trillion miles
dozens of light years
I hope this channel grows and stays around a long time. I'm sick with Covid and am having the worst time sleeping. This is fascinating and relaxing enough to distract me from being cranky and ill. ❤
Stay inside and get vitamins, we don't want that stuff to spread again
It's actually absurd to think we're alone in the universe.
Blows my mind everytime i think about it. How tf our earth function so perfectly and we have yet to come across other life in space…
We have no idea, there are planets that we can't even see. We can only go so far so we have no idea.
@@BestCarMediashit I think we have already on some low key shit
nope. we are alone
Lol maybe that's where they will send the frozen IVF babies to be raised by the new androids.
The thing that really gets me about this is that we're only identifying planets as habitable zone based on where life we're used to could exist. There could be life that we could never even perceive, and that life could also never perceive us.
True, but I’d hardly call it anthrocentrism. We’re looking for carbon-based life because carbon is extremely common in the universe and easily forms bonds with other atoms, which allow for complex molecules. Due to just basic chemistry carbon-based life would need water and oxygen so we’re looking for that.
The next best element to look for is silicon…but it’s only 1/10th as abundant as carbon and forms only a fraction as many compounds (and half of them are _with carbon)._ And all the other elements are even more unlikely.
The universe has some fundamental rules to it. I mean yeah sure maybe there’s life out there based on non-Baryonic matter or something, bunch of Photino birds making nuisances of themselves or whatever. But we have no possible way to detect them and no idea how they’d function so there’s no real point in looking. For now, given its abundance, it makes the most sense to stick to looking for carbon-based life.
Correct, but that's is all we can do. We cant see what we cant see.
@@RogueShadows - Yea but we hardly understand all the rules of the universe... Look at how little we understand about dark matter and dark energy for one... But I'm not opposed to us searching. If we find something, that's good.
@@peternielsen8601 - I know that. Did I say I opposed what we're doing? No...
Yeah I always wonder if there are living things on planets that are super hot or super cold. There must be. Even though it's not suitable for us, it might be suitable for other things. That's so scary to think about.
Very good descriptions and graphics. An enjoyable presentation.
The more I see videos like this, the more I’m starting to become convinced that humans may not be able to survive somewhere else even with relatively habitable conditions around those stars…For instance those other places mentioned have different gravity levels, different power structure of the stars, different atmospheric pressure etc….Every fiber of our being is in direct relation to the variables/settings of Earth. It likely wouldn’t translate somewhere else. Our bones, blood, skin, muscles etc would all be affected in a negative way. Earth is our home.
This is why I find the idea of humans living on Mars to not only be ridiculous, but possibly a disastrous waste of time and resources. The physiological changes that occur in humans who are off-planet for long periods of time may be insurmountable, in any case.
@@robynliteracy7057 I agree Robyn that’s a great point. When I initially heard about the idea of terraforming Mars the concept seemed interesting and I told myself it makes the most sense that humans need to colonize other planets to increase the chance for the continuation of our species in the long term.
But then I started realizing how unbelievably barren/cold/desolate a place like Mars is. Living on Mars would be a nightmare not to mention how ugly the planet is compared to Earth and how the quality of our lives would be exponentially worse even if we survived the toxic atmosphere. There’s a very depressing quality when thinking of leaving Earth and moving backwards from the living standards we are accustomed to. Thanks but no thanks!
So you don't think we're able to adapt look at how we've changed ourselves and Earth
@@shaanchaudhry5719 We need a planet with active inner core to shield from toxic radiation that our sun gives. And thats another factor where Mars fails completely. There is no active inner core planet in our solar system beside earth. All others are barren, lifeless, unshielded. An electromagnetic shield is the first thing I would require in order to survive on a planet orbiting its sun. Radiation from the sun is so powerful it penetrates the earth's atmosphere creating O3 from O2. Imagine to be exposed to the sun's radiation unshielded. It is an instant death. Burns from radiation and immerse energy levels. Even that far from the sun as we are (or Mars is).
@@johnrichmond8606 We earned our place here. Every fiber of our being originated with the ingredients found here. Evolving on our host planet is completely different than going to a remote planet.
Learning about all this makes me realise just how perfect the conditions of our solar system, sun, even our own planet is. We’ve found thousands of planets out there and none are even close to as perfect for life as earth. The odds of our planet being so perfect for life must be insane.
And that alone might be why we're possibly the only advanced lifeforms

Perfect voice for narration. So calm on the ears.
Although red dwarfs are smaller and cooler than the sun, they tend to spin faster and be more active. This means they give off a lot of radiation that would be harmful for life on any planets that might orbit them.
I thought the same. These planets need a much thicker atmosphere than on Earth to protect them from the crazy radioactivity created by their red dwarf suns. But a thick atmosphere would cause the planet to be very cold because not enough sunlight could reach the surface. For reasons like this, it is almost impossible to find habitable planets around red dwarfs.

Why terrifying? It's not like physics is going to allow us to meet. So we need to be the best caretakers of our planet as it is the only sustainable one in our solar system. Ooops....to late... Next species step right up and takes your chances !
I watched to the end waiting to hear about the planet that was more habitable than ours but still waiting!

Yeah, they're ALL pretty iffy, huh? Especially since this video was based SOLEY on imagination and conjecture and a LOT of wishful thinking.
Keep researching and we might get to suprized ourselves later sooner.
We could use a sense new Reinheritance comforts and new planet retrogrades.
Awesome sharing grace❤️🤍💙
The Goldilocks Zone all depends on the type of Sun you have. The Goldilocks Zone is different around each Star. Bigger, hotter Stars like the Sun, a G-type Star, have a wider habitable zone, while smaller Red Dwarfs confine habitable planets to a narrower range.
This makes me remember to never take a day for granted. What we have here on earth is truly remarkable. We are very lucky
They haven't found any habitable planets.

Yes. The title doesn't fit the video at all
@@shafootodess some other way I guess lol
Solar systems more habitable than ours might fit, as some had multiple planets in the sweet zone.

Gliese 667 is 22.1 light years (or 207,863,753,281,600 Kilometers) from the Earth . If you were to travel at the velocity of the Helios 2 probe, which traveled at 252,792 KPH , it would take approximately: 93,866.65 years to reach Gliese 667. The fact that they are even talking about this is so mentally backwards.
@@Valkonnen No, not really.
First, if we want to really boil this down to what is possible and what we could do, start taking the current state and growth of technology into account. Robotics being a key point I will highlight here. I have a standing preditction that in 10 years or less we will have the means and ability to set up a ship, give it a robotic crew, launch it to space, send it to Saturn, and set up a station to analyze and identify minable material in the asteroid belt. Lets assume that at this time there are no developments made regarding space flight for a moment.
The first mission the crew of the ship will have will be to establish a harvestable resource to maintain engine fuel. Theoretically possible but not enterally proven. Assume for a moment it does work, we could theoretically have (in the next say 50 years) an operational automated program to establish and operate a station in space with the sol purpose to locate, mine, and transport resources back to earth without carrying a human crew.
Knowing that, It is safe to assume any exploration efforts made will probably remain in our solar system. However, we do have the possibility after reaching that point of setting up a ship built for long distance travel using automated systems to safely carry unfertile but preserved eggs and sperm to basically send a "seed ship" to a planet of our choosing to populate it with new life. Now, obviously this has its own challenges and we are assuming that even preserved the necessary requirements to carry life to that planet will stay preserved is questionable, but for the fun of the hypothetical, assume it does.
The ship would be able to operate on low power using little fuel for most of the flight until it had to make alterations to trajectory. Once it got say 30 years in range of the planet, the ship could be equipped to dethawed, fertilize the eggs, nurture the offspring, and raise the kids to adult hood before they got to even reach the planet. By the time the crew got there they would be in their 30s, Granted, that hypothetical has a lot of ethical dilemmas let alone logistic and it is arguable by then we may develop long term stasis technology to just send full grown trained volunteers instead. Still, this sort of transportation in some way is going to be mandatory for colonization. Unless we hit some serious breakthroughs in space flight.
What we can do until then is at least locate places we can keep an eye on as possible settling locations if we ever get the chance to try it. Most of these observations are just that, observations. And doing research now on possible habitual worlds to explore is not useless. And there is no telling what else we could learn just from star gazing into the universe.
Some of these "super habitable" planets make me wonder if life started so abruptly and was able to spread so quickly that it hinders the complexity. Like if the environment doesn't challenge organisms enough, they might have found some happy stasis as an algae that has no reason to evolve
What im wondering about is how much the earths wobble/seasons affected evolution. And how much or moon does. Those 2 combined maybe put evolution in a certain speed because species had to be adaptable.
Right. I’ve thought the same thing. It’s like they are almost “too comfortable” where here things had to keep fighting and changing and evolving to live.
@@fitfogey
Interesting thought, but I don't think that's very likely tbh. We should not assume that life on other planets would be easier or more stable and sustainable than it was and is on Earth.
Other Earth-like planets too would likely experience periods of heavy tectonc activity leading to eruptions and possibly extinction events. They too could be hit by intense bursts of radiation or asteroids. A rogue planet or giant asteroid could pass by close enough to tilt their axis, induce or affect rotation around their own axis, or even change their orbit around their star (fingers crossed that this doesn't occur on Earth for the foreseeable future, lmao).
Those things could happen anywhere on any habitable, Earth-like exoplanet. Earth probably is not unique in that regard.
A planet of algae is an incredible niche for an awaiting predator to evolve to graze on them
It really does being up questions like, what happens if people are in a habitable area but don't have access to the things we're accustomed to - if they regress back into tribal like, that could raise the question of if that could have happened before even. Obviously that's questions alone, not much consideration included, simple speculation.

Even if we as humans have discovered potentially habitatable planets outside of our solar system and even galaxy, there's no way EVER in our lifetime we'll ever get there.!!
My biggest thing about these videos is it just shows how much we focus on specific planets. While I know we are searching for planets that could host life for humans, we are dismissing other planets that could host other life.
We don't even know if any of the Gas Giants have life on their planet cause we can't go there. There is no surface (or at least no known surface) and the gravity would be too much after a certain point is reached. Yet that doesn't mean no life is there at all. Just like how different life has adapted to places on Earth, the same could be said for other planets.
This would explain why we haven't found any signs of life outside our own planet. We are only looking for specific conditions that support life. Now you might be asking a particular question. If life is out there, why haven't they made contact with us? The same reason would apply to them. If their planet structure is deems\ed as "inhabitable" to us, they may deem our planet structure to be "inhabitable" for them and thus rule our planet out as a place for life.
Fr, imagine those aliens on Jupiter thinking that life can't even be possible on earth, vice versa, Lmao
Being in the habitable zone is one thing but you also have to take into account bacteria and the whole ecosystem of the planet. I doubt we will ever see a planet more "habitable" than Earth because of this.
us going to another planet in a habitable zone will do to humanity what whites did to native populations w smallpox.
We will never even get close to inhabiting those other worlds. Never. Not ever.

One light year is approximately 6 trillion miles. With current technology and understanding of physics and time, it would take tens of thousands of years to go just that distance, let alone 23 light years. The question of time and dimension would need to be solved, with the technology to do it, before space travel could become a possibility.

Wonderful. On my wish list would be rocky watery worlds in the Goldie lock zone. I'm asking for much but water is quite important (and very pleasant!). I read somewhere that the light shining from a star, through the atmosphere of an exoplanet can sometimes be perceived all the way to our instruments! (spectrum analysis of H2O, I think).That's quite a feat. Meaning that in some cases, they were able to ascertain the presence of water vapor in their atmosphere. Could you tell us examples of this, still evaluated with other favorable parameters like Goldie lock zone, is it also rocky (not just gas) and of the right size? Thank you so much.

Here is a future topic to consider maybe. I was wondering about the possibilities of how Earth achieved it's vegetation from seeds of real things rather than imagination. I can only come up with two possibilities myself. 1) The Sun, is actually the burning core of a larger planet that exploded, or was impacted to the point of destruction. If this original planet already had vegetation, then Earth is a remnant piece, and our positioning to sustain life makes our results quantifiable there. 2) Other pieces of space debri, from outer areas with seeds in the composition. Impacting Earth early on. Otherwise, we have to determine how seeds were made out of nothing but some hot air potentially.
This is extremely exciting to know and I am convinced that we are not alone
this really fires the curiosity out of me

Someone once said…,”There are intelligent life here in our universe❣️It is right here on Earth 🌎 ❣️🎵🎶”
Hi I was just wondering is this a free of charge site if yr wanting to subscribe, as I have already I just don't want to find out down the line that there's hidden charges is all?!! I hope I've made sense here with this question!! And very interesting stuff to learn about I've always had an interest in the unknown about space & all wat it has to offer!!
This is misleading. From the title, completely misleading, to some of the information within the video. First of all, all of this is very speculative right now. There is no evidence that any of these planets, or any other we’ve found so far, supports any life, or can.
There are many things that determine whether a planet can retain an atmosphere. Size, distance from their star, whether it has a liquid core, how stable the star is, and how close neighbor stars are, etc.
"More habitable than Earth" - Earth's pretty habitable, seeing as it's the only planet known to contain life.
Like saying the grass is greener on the other side!
"Planets can always be wetter, look greener"
Not to mention a visit to even the closest possible planet with life would take thousands of years of fuel production; and even the nicest of estimates put it at a 50,000 year travel time. So there’s no way anyone alive today can prove it unless something comes from out there claiming to be from out there
If a planet is more habitable than earth would definitely have life. What would we do? I know just hope we could be dominant over the life and take over the planet, kill all the life that was there and then ruin that planet too. Humans, a stain on the universe.
"Known"
Realistically, even if we found a million potentially habitable planets, we would still not know for sure whether or not life exists beyond Earth. This is because we do not yet have the technology to travel faster than the speed of light, and even if we did, we would still need to develop the technology to detect life on those planets. This raises the question: are we alone in the universe, or are we simply too limited in our technology to find out?
I argue that we should be putting more efforts into developing faster-than-light travel technology instead of billion-dollar telescopes. If we want to truly answer the question of whether or not we are alone in the universe, we need to be able to travel to other stars and planets.
Sadly, the world never puts money on physics unless it's for weapons, so this is probably not happening anytime soon.
Star Trek resolved all those issues 🤣. Heck even a million light years away they speak American English. That’s amazing!
Astrophysicist Hugh Ross has stated that we have discovered almost 7,000 planets, none of which are close to being able to sustain life. One exception: Earth

I always find this stuff fascinating, because to me the concept of the habitable Zone assumes that life can only occur were their is water. What about life that isn't made or doesn't need water to exist. Just because we never found evidence to support that doesn't make it not possible. Look at the concept for Silicon based life forms, they would be breathing Sand and would be able to endure much hotter temperatures.
There is a neat video explaining why silicon-based life is pretty much not possible
Because when guesstimating what planets are worth investigating regarding habitability we're trying to *narrow* the list down. Simple, known variables are better for that.
The experts are very careful to say "life as we know it", because theyre not trying to get tripped up in the definition of life. Some places we will never look for life simply because we know WE can't live there.
How about the concept of a planet being inhabited by creatures that are not life forms, such as robots for example.

It's marvellous what scientists have found out about distant stars and their XO planets. It makes me think how perfect the earth is placed for life in all its diversity as we know it to survive. Plus, we have a planet out there that acts as a dustbin to trap asteroids and meteorites that could potentially hit Earth. And although there may be a planet that supports life somewhere out there, at this moment, we haven't found one. So, to me, it's important that we look after what we have here on the planet we call Earth and home.
A planet thats devoid of life aka food isn't habitable.

IN AN INFINITE SPACE, we are not all.@@frankp7411
Our existence is just a blink in Earth's lifetime. Some planets had life but lost it, some will have in the future. Millions of years able to change everything.
One thing that most scifi movie failed to show is that The biggest threat of a habitable alien planet is its microorganisms. Who knows what kind of disease that it can cause to our human physiology.
The idea that pathogens that evolved for completely different conditions would find us appetizing is an odd belief. Most pathogens can't comfortably infect all life on this planet, and they evolved to do so, it's more likely our immune systems would crush anything we encounter.
Thats exactly how the aliens in war of the worlds were overcome
@@liwojenkins Using adjectives like appetizing and comfortably for single celled organisms signals to everyone that you're an idiot.
it's absolutely absurd to believe that we have the technology to observe habitable planets at distances we can't intellectually perceive.
Love your channel guy! Keep up the good work!
It's definitely very interesting, but at 23 Light years away, it would take over 300 thousand years to get there by conventional rocket. We might as well call that impossible. Even if there was an advanced civilization there, it would take us 23 years to send a message and another 23 years to get a reply. Obviously, we need a warp drive or a third stage guild navigator to fold space.
Exactly.
Hahaha awesome Dune reference. I f@ckin love you, bro!!
Spacetime is a mathematical concept you cant wrap something doesn't exist
Alpha Centauri will be an interesting presentation
"More habitable than Earth" is such a goofy idea... we are perfectly adapted for Earth.
If I could choose a super power, it would be to have the ability to visit all these planets and film my journeys for a TV series.
If there is trillions of galaxies out there where each galaxy has trillions of stars in it and each star has its own solar system with its orbiting planets, isn't it possible to have the exact planet formation similar to the earth formation out there? or to put it in another word, is it possible that there is only one earth-like planet formation in this massive and vast universe?
both things are possible it just depends on the odds...
say there's 10^30 habitable planets out there... huge number
but then say the odds of life spontaneously happening given the right elements and the conditions of the planet being exact right and that life not getting killed early by radiation or planetary impacts etc etc is 1/10^40 ... then quite frankly it's a miracle life even sprouted once
so there's just too many variables
No planet, no solar system was ever created from a bang of nothing.
Agreed
we are living on tha planet known as earth, i believe planets are real.@@marcbordeau1702

The habitability of the Gleise planets is still in the fantasy zone. Too hot for us, or too cold for us, or too much exposure to the flares of the star.
Mankind’s optimism is astounding.
When can we visit it?
“Earth is about 1 AU from the sun”
Considering an AU is the distance from the sun to the earth, there’s no “about”. It is 1 AU exactly
an AU is the mean distance and the Earth is sometimes closer and sometimes further away so it may sound weird but his wording is not wrong.
It's actually absurd to think we're alone in Earth itself.
Besides when we have been searching for decades for… anything and have only found a couple one called organisms if even. Probably some viruses. It’s rare if there is other life on earth with how we record currently
we JUST started leaving our own solar system and we are looking LIGHT YEARS beyond earth. We are brand ass new at this. Human time is NOTHING compared to cosmic and geological time. The best humans can do is social fn media. We are a trial and nothing more. Humans do not matter outside of your own family unit, you have zero value to the world @@Shitockiful
It's very impressive to see such worlds, but how can you possibly claim they are MORE habitable than earth?
glizzy 667 cc seems like a nice place to live on
That's awesome how we are able to use a thermometer to measure the temperature of those planets light years away.... simply amazing.
they have no bloody idea.
Goldilocks zone doesn’t mean it’s habitable, Venus and Mars are in the habitable zone too.
Even if habitable also doesn’t mean it can harbour life.
You mean our life...life can be very strange and surv very different conditions
@@rji5377Exactly, Fish that live deep in the oceans where the pressure is enough to crush your skull, No light can reach and every creature is blind, Some animals have evolved to respond to those conditions.
@@Vurinati shit many live in methane or in surfer volcanic areas. Tartagrades can survive space . Who knows what's out there
There's lots of variables that cannot be answered from this distance because of observation from this distance is impossible.. There are also mass (of this planet), our moon's positions as a stabilizer, and other arrangements.. Since there are trillions upon trillions of stars, there's going to be different variations of this Earth and other planets.. but since patterns repeat there's probably a lot of similar planets.. Just imagine if every corn on the cob being exactly them same.. There's also different timelines... So there you have it..
It is funny that we are not sure about Mars, but are sure about planets that are light-years away.
it’s even crazier to think that it’s probably gonna be another 500 years before humanity can even reach another solar system
I really think the universe is just so vast that the thought others aren't out there is unrealistic.
The problem with these red dwarfs is the for the planets to be in the habitable zone, they generally have to be very close, which often means tidally locked. And that means one side will be very hot and one side very cold.
Life would still be possible. You'd have a strip across the planet of a very stable average temperature. It would be a very different weather and climate, of course
@@cristobalschulkin6948 I think it is wishful thinking. Or at least for humanoid life. Possibly plant life. But animals? Advanced life forms?
I love to travel there for a vacation. What would be the fastest way to get there?
Any planet without humans is by definition more habitable than Earth 😂
How can you have a planet more habitable than Earth? We actually live here.
perhaps you can find a planet free of earth quakes, tornadoes, cyclones, tsunamis, hurricanes, extreme heat, extreme cold, solar flares, switching poles, asteroid impacts of extinction level, viruses, bacteria, predators...there are a thousand ways to die in the west, there could be a planet more habitable than Earth. Now, finding it and getting to it, we won't live to see that.
More water, oil, and resources.
people live in deserts but that doesnt mean deserts are as habitable as grasslands with temperate climates.
in that same way another planet could be more habitable than earth.
@@djkenardo9671it's not stupid. Humans evolved in Africa, and still live there, so by your logic it's stupid for me to say Europe is more habitable than Africa.
title: Scientists Discover Planets MORE HABITABLE Than Earth
conclusion: you'd die... not really more habitable, is it?
I think any system of sufficient complexity could promote life. Temperature gradients, a polar solvent for redox reactions [not necessarily water] , an active plate tectonics system for turnover of minerals, and time. There are only about 20 elements necessary for life as we know it, with the rarer ones providing nuances to "CHON' structures. But the periodic table is iterative. Chemical properties are similar [but not the same of course] as mass increases. Monovalent, divalent and triple valence metals for example. Different temperatures and pressures many allow "analog" systems to evolve. Perhaps silicon instead of carbon, and so on. Acids and bases abound. So anions and cations. Also, there needs to be metabolism and some form of storing information, like nucleic acids, or some equivalent system.
We find it hard to recognize first life on our own planet, if you go far enough back in the fossil record. Finding small, cell-like structures that could be strictly of non-living character, or the simplest life or proto-life systems.
We can't even agree if viruses are alive or not, because without hosts, they are inert, but inside a host, they gain the ability for life-type functions. For obvious reasons, viruses are not first life, but the very first life must have shared some features with viruses.
That life came from non-life is speculative, but we have an embarrassment of riches now. Multiple ways that life could have started-from ribozymes, to bi-layer lipid membranes with some metabolic chemistry inside, clay or other substrates, and so on.
Living the life outside the solar system, sounds exciting and hopefully those habitable ones will give us comfort

If Evolution is a fact - then just perhaps on this planet these humans evolved to fit requirements.

A segment from 'Saved by the Light of the Buddha Within'...
My new understandings of what many call 'God -The Holy Spirit' - resulting from some of the extraordinary ongoing after-effects relating to my NDE...
Myoho-Renge-Kyo represents the identity of what some scientists are now referring to as the unified field of consciousnesses. In other words, it’s the essence of all existence and non-existence - the ultimate creative force behind planets, stars, nebulae, people, animals, trees, fish, birds, and all phenomena, manifest or latent. All matter and intelligence are simply waves or ripples manifesting to and from this core source. Consciousness (enlightenment) is itself the actual creator of everything that exists now, ever existed in the past, or will exist in the future - right down to the minutest particles of dust - each being an individual ripple or wave.
The big difference between chanting Nam-Myoho-Renge-Kyo and most other conventional prayers is that instead of depending on a ‘middleman’ to connect us to our state of inner enlightenment, we’re able to do it ourselves. That’s because chanting Nam-Myoho-Renge-Kyo allows us to tap directly into our enlightened state by way of this self-produced sound vibration. ‘Who or What Is God?’ If we compare the concept of God being a separate entity that is forever watching down on us, to the teachings of Nichiren, it makes more sense to me that the true omnipotence, omniscience and omnipresence of what most people perceive to be God, is the fantastic state of enlightenment that exists within each of us. Some say that God is an entity that’s beyond physical matter - I think that the vast amount of information continuously being conveyed via electromagnetic waves in today’s world gives us proof of how an invisible state of God could indeed exist.
For example, it’s now widely known that specific data relayed by way of electromagnetic waves has the potential to help bring about extraordinary and powerful effects - including an instant global awareness of something or a mass emotional reaction. It’s also common knowledge that these invisible waves can easily be used to detonate a bomb or to enable NASA to control the movements of a robot as far away as the Moon or Mars - none of which is possible without a receiver to decode the information that’s being transmitted. Without the receiver, the data would remain impotent. In a very similar way, we need to have our own ‘receiver’ switched on so that we can activate a clear and precise understanding of our own life, all other life and what everything else in existence is.
Chanting Nam-Myoho-Renge-Kyo each day helps us to achieve this because it allows us to reach the core of our enlightenment and keep it switched on. That’s because Myoho-Renge-Kyo represents the identity of what scientists now refer to as the unified field of consciousnesses. To break it down - Myoho represents the Law of manifestation and latency (Nature) and consists of two alternating states. For example, the state of Myo is where everything in life that’s not obvious to us exists - including our stored memories when we’re not thinking about them - our hidden potential and inner emotions whenever they’re dormant - our desires, our fears, our wisdom, happiness, karma - and more importantly, our enlightenment.
The other state, ho, is where everything in Life exists whenever it becomes evident to us, such as when a thought pops up from within our memory - whenever we experience or express our emotions - or whenever a good or bad cause manifests as an effect from our karma. When anything becomes apparent, it merely means that it’s come out of the state of Myo (dormancy/latency) and into a state of ho (manifestation). It’s the difference between consciousness and unconsciousness, being awake or asleep, or knowing and not knowing.
The second law - Renge - Ren meaning cause and ge meaning effect, governs and controls the functions of Myoho - these two laws of Myoho and Renge, not only function together simultaneously but also underlies all spiritual and physical existence.
The final and third part of the tri-combination - Kyo, is the Law that allows Myoho to integrate with Renge - or vice versa. It’s the great, invisible thread of energy that fuses and connects all Life and matter - as well as the past, present and future. It’s also sometimes termed the Universal Law of Communication - perhaps it could even be compared with the string theory that many scientists now suspect exists.
Just as the cells in our body, our thoughts, feelings and everything else is continually fluctuating within us - all that exists in the world around us and beyond is also in a constant state of flux - constantly controlled by these three fundamental laws. In fact, more things are going back and forth between the two states of Myo and ho in a single moment than it would ever be possible to calculate or describe. And it doesn’t matter how big or small, famous or trivial anything or anyone may appear to be, everything that’s ever existed in the past, exists now or will exist in the future, exists only because of the workings of the Laws ‘Myoho-Renge-Kyo’ - the basis of the four fundamental forces, and if they didn’t function, neither we nor anything else could go on existing. That’s because all forms of existence, including the seasons, day, night, birth, death and so on, are moving forward in an ongoing flow of continuation - rhythmically reverting back and forth between the two fundamental states of Myo and ho in absolute accordance with Renge - and by way of Kyo. Even stars are dying and being reborn under the workings of what the combination ‘Myoho-Renge-Kyo’ represents. Nam, or Namu - which mean the same thing, are vibrational passwords or keys that allow us to reach deep into our life and fuse with or become one with ‘Myoho-Renge-Kyo’.
On a more personal level, nothing ever happens by chance or coincidence, it’s the causes that we’ve made in our past, or are presently making, that determine how these laws function uniquely in each of our lives - as well as the environment from moment to moment. By facing east, in harmony with the direction that the Earth is spinning, and chanting Nam-Myoho-Renge-Kyo for a minimum of, let’s say, ten minutes daily to start with, any of us can experience actual proof of its positive effects in our lives - even if it only makes us feel good on the inside, there will be a definite positive effect. That’s because we’re able to pierce through the thickest layers of our karma and activate our inherent Buddha Nature (our enlightened state). By so doing, we’re then able to bring forth the wisdom and good fortune that we need to challenge, overcome and change our adverse circumstances - turn them into positive ones - or manifest and gain even greater fulfilment in our daily lives from our accumulated good karma. This also allows us to bring forth the wisdom that can free us from the ignorance and stupidity that’s preventing us from accepting and being proud of the person that we indeed are - regardless of our race, colour, gender or sexuality. We’re also able to see and understand our circumstances and the environment far more clearly, as well as attract and connect with any needed external beneficial forces and situations. As I’ve already mentioned, everything is subject to the law of Cause and Effect - the ‘actual-proof-strength’ resulting from chanting Nam-Myoho-Renge-Kyo always depends on our determination, sincerity and dedication.
For example, the levels of difference could be compared to making a sound on a piano, creating a melody, producing a great song, and so on. Something else that’s very important to always respect and acknowledge is that the Law (or if you prefer God) is in everyone and everything.
NB: There are frightening and disturbing sounds, and there are tranquil and relaxing sounds. It’s the emotional result of any noise or sound that can trigger off a mood or even instantly change one. When chanting Nam-Myoho-Renge-Kyo each day, we are producing a sound vibration that’s the password to our true inner-self - this soon becomes apparent when you start reassessing your views on various things - such as your fears and desires etc. The best way to get the desired result when chanting is not to view things conventionally - rather than reaching out to an external source, we need to reach into our own lives and bring our needs and desires to fruition from within - including the good fortune and strength to achieve any help that we may need. Chanting Nam-Myoho-Renge-Kyo also reaches out externally and draws us towards, or draws towards us, what we need to make us happy from our environment. For example, it helps us to be in the right place at the right time - to make better choices and decisions and so forth. We need to think of it as a seed within us that we’re watering and bringing sunshine to for it to grow, blossom and bring forth fruit or flowers. It’s also important to understand that everything we need in life, including the answer to every question and the potential to achieve every dream, already exists within us.
