We often assume that advanced technology will make it easy for aliens to colonize space. But what if space exploration is always difficult, no matter how advanced you are?
Let’s travel back in human history, to the colonization of Oceania over 5000 years ago, to find parallels between ancient explorers and extraterrestrial civilizations.

An assumption often made is that spacefaring civilisations will be after planets, rather than resources for habitable megastructures and fleets
My only assumption is rule 34. Can't wait for my interspecies experience.
@@gentlemanvontweed7147 Ummm... I guess look at Mass Effect (or any sci-fi franchise really) for a preview? There's probably a good chance you won't be alive to witness it.
Just assuming other species do spacefaring is already a huge assumption.
If FTL is impossible, the resources required to launch colony ships across the interstellar void to destinations that may or may not support them seems wasteful. Especially when you consider that with same resources you could build another orbital habitat that could house millions. Which would you rather, build another habitat to reduce the strain on earth's ecosystem, or send a small group of people on a generational trip that will probably end in failure? Humans would probably just densely populate the solar system rather than spread out to other systems.
@@etienne8110 Not really. Expansion due to overproductive reproduction is a universal trait of all lifeforms on Earth. It's not a huge leap to assume that alien life behaves similar.
Statistically speaking, no matter how good Fermi is at approximating things, we're still externalizing from an observation on a sample of N=1.
Shut up nerd
Is that wrong?
Yes it's really really stupid to say because we don't see aliens they don't exist.
sample size is everything!
Well considering that there's microbial life on asteroids and other planets, I'd say it's more of like N=1.1 lol
7:35 Flirted with extinction might be one of my top kurzgesagt phrases
Weirdly poetic :)
Humanity is already at a point of having unprotected sex with extinction imho, the only question is wether or not we can find the cure for the extinction-level STDs we're getting.
I've already heard that phrase in a melodysheep video, titled "THE HUMAN FUTURE".
What about “How to Destroy the Universe”
I think humanity has not just flirted but exchanged numbers with and flashed a boob at extinction.
To extend the analogy - knowing what happened when other civilisations discovered the Polynesians suddenly makes the idea of us meeting with aliens pretty scary
They meet us every single day, have done so for a long time now.
@@steelswarm2721Take your meds loon.
Kind of a tangent, but I've noticed a lot of media from the post-colonial seem to be unintentionally expressing fear and guilt at what built modern society. Especially the alien invasion.
People with an unfamiliar culture and society wielding advanced technology show up and subjugate our entire society in an attempt to wither extract resources, assimilate, or exterminate in order to take the land.
The imperial/colonial guilt inherent to the genre doesn't even seem intentional. Especially in the 80s and 90s. But it's there because art reflects life.
It all depends who meets who first
I don't know, they have it pretty sweet now.compared to then.
"Mars is the worst,.... except Venus is even worse" I giggled at that for some reason😂
yeah venus makes mars look tame by comparison. it's like a hellish landscape with sulfuric acid and carbon dioxide clouds
Me too.
Wait until you find out about Uranus.
05:01 way too expensive, too expensive, still too expensive😂😂😂
Hey Venus gets less credit than it deserves, sure the surface is hellish but go a few kilometres up and it's a warm earth like temperature and pressure with adequate radiation protection, the same gravity as earth and no acid rain.
I see the prospect of making a balloon to be far more in our grasp than making artificial gravity or an atmosphere and magnetic field

@@phelan_pt where?
I'd love to see an episode exploring this theme more, regarding all the means of communication that other civilizations might be using, that we are not or cannot yet look for.
Apparetnly they use the cosmic web for communication and travel.
I feel like for interstellar communication or interaction between civilizations. You need to have one of three things:
1) Travel speeds above light speed
2) Wormholes
3) a species which ages very slowly. If their life expectancy is 2000 years, traveling for some hundred years is still feasible
Sadly above lightspeed is impossible
I mean technically as long as you have enough dV, you can get interstellar voyages down to decent levels (at least, for nearby stars), but breaking the lightspeed barrier is essentially impossible, no matter how it's done. The good news is those *on board* the ship would experience time even slower, to the point where time experienced increases non-linearly with distance, so that's nice at least.

There's one complication: we don't actually need to live on planets. With the high tech that allows interstellar travel, you can easily build giant space stations to live on, powered by your friendly neighbourhood fusion reactor (your Sun) even if you yourself haven't figured out fusion.
And if you find a decent sized rock with some uranium or thorium in it, you can live on that for thousands of years. This would allow you to travel interstellar distances, just by hanging out and waiting for generations on a rock. Also, the stars move, meaning that any civilization in a star system that lasts for millions of years, will inevitably have a close encounter with another star.
But a planet is always preferable though. No tech can match the scale and freedom you have on a planet (that suits your needs).
You could get close though, with enormous stations powered by an artificial sun and other trickery. But at that point it's probably easier to just find or terraform a planet.
Gravity wells may well be for suckers! In the distant future it may well seem strange to live in the constrictive environment of a planet.
@@joost199207 Even in real life, we have people living in vehicles, like trucks and boats. If it can be done, it will be done.
While I get what you are saying, unlimited energy is not everything required to live, water is important too. Thus, finding a planet with water and actually living on it would be much more cost efficient than transporting that water to a space station.
I just want to say, analogizing Oceania to space is brilliant
how lol. you cant fish in space, it doesnt rain and there is no wind.
i think he meant from an exploration standpoint
We've been doing it for years. The number of sci-fi medias that don't equate spaceships to... well, ships in space, is in the single digits.
I'm also impressed by them using the term "Oceania" correctly, so many people incorrectly lump in the entire continent of Australia.

1. Complex life being really difficult to evolve and 2. the chances that two civilizations occupy the same epoch in time really should not be underestimated.
Neither should the scale of things.....
It takes A LOT of evolution for a world to evolve a species that has at least human level intelligence and is even more advanced than we are. If you look at our world over a span of 4.5 billion years you will see countless species of life from the smallest microbes to the largest whales and dinosaurs yet in all of that time our world has only produced ONE species that is somewhat tech advanced. I say "somewhat" because we sure are not at the level of the aliens in this video.
I do not believe that life is rare. I think its very common but that only a very very tiny percentage of worlds with life get to the point of advanced technology. I believe that almost all inhabited worlds just have plants, animals and sometimes beings with human level intellect but low technology.
2 high tech species being near each other (within 10 light years lets say) is like 2 state lottery winners happening to be next door neighbors.
I've heard the same

Another thing is the jump from complex life to space faring societal life.
Complex life was on Earth for well over a Billion years, full brains, cortexes, highly specialized abilities etc etc were here for hundreds of millions of years and not a single one of them figured out you could use rocks to break stuff. Let alone space travel. Humanity existing is a very recent thing, humanity having space travel is a very very VERY recent thing in the geological scale.
"would you go to war because someone's great grandfather killed yours"
Actually yes, we've been doing it for centuries.
right, because Germany and France are famously still at war
the century-long conflicts that endure, endure because you have a continued personal stake in it (e.g. religious), and often occur over fighting over a singular resource (be that land/rights/etc)-which isn't really the case in separate solar systems
@@SisterSunny so nobody will have stakes in a planet which they've already put tons of resources into?

Love the idea of stars like islands and also what a great sponsor!!!
After reading the 3 Body Problem series, this is a much more optimistic view of the universe. But I’m still leaning towards Cixin Liu’s Dark Forrest idea. Pessimistic, but understandably so. It would be awesome to see a video from you tackling that series and its ideas.
It's a cool story, but it ignores some very easy solutions for safe interstellar contact.
Just put goddamn relay beacons in interstellar space and send signals from there. You don't have to reveal the location of your planet or solar system in order to establish interstellar contact. And if all technological races would use these relays for safety, then they might as well share knowledge and cooperate peacefully. It's like the internet anonymity.
😂😂😂you r right
“No man’s sky” is a perfect game to represent this idea. If you play the game blindly, you may never find a earth like planet, even a pretty planet can have a environment or creature that will kill you
Yep. And in that game there are galactic empires so maybe truly at a certain tech level I becomes trival.
Hilariously, on my current save, I spawned on an inhospitable ice planet... whose moon is basically perfect. It has zero environmental hazards, zero hostile creatures, and I've barely seen any sentinels on it (they are not hostile anyway).
Bonus points: I built a base on the ice planet because it's prettier, just on top of a random hill that had vaguely good views and was near a ground station. Then, after I unlocked the resource visor, I discovered that I accidentally built right next to a dioxite deposit... which effectively means my life support will never run out, because I have way more dioxite than I can possibly use up on charging it.
I wish they had gas giants you could float around in.
In my 400+ hours of playing no man's sky I landed on around 2000+ planets on my journey through black holes to the centre of the galaxy.
I came across 3 planets that were similar to earth.
The first one was the most similar but had no fauna.
The second one had fauna and realistic mountains and continents but was incredibly toxic.
The third one ticked all the boxes but had weird floating mountains so was a no go.
I'm still trying to find a planet to build my homebase on but so far have had no luck.
I should have just stuck with the third one.
tbf theres plenty of creatures on earth that can kill u too

I find one of the greatest ironies of interstellar colonization is that if you have the ability to create ships to travel those vast distances, or settle on the surface of extremely marginal planets like Mars, you've also the ability to make artificial habitats, bottle worlds, completely undercutting the need to colonize another planet in the most extreme version of an invasive species.
This actually makes colonizing other systems easier because you don't need to look for planets to live on, the asteroids within a system become a more valuable resource because of accessability. This also means you don't need to go sailing off vast distances because just about any system will do, which means expansion happens in small jumps rather than great leaps. This keeps inter-planetary civilizations quite compact, even if each system in that civilization might have a much greater population than a planet might sustain.
Yeah and any civilization near a blackhole has a megastructural starting bonus since nearly all blackhole megastructures are fairly easy compared to other objects since its WAY easier to collect energy from a blackhole than a star resource and time wise
I feel that this is like saying "why did the europeans colonize america if they had infrasturcture in europe?"
or something like that
@@generaldelasmontanas2699 Yeah, exactly. People will colonize other planets because we .. emmm.. don't like other people sometimes. And distance is good way to be out of reach of those people. Ask Europeans which go to the New World to go out of European monarchies sphere of influence.
@@generaldelasmontanas2699
It bears pointing out that what drove the initial wave of exploration from Europe wasn't to settle somewhere, it was to make ridiculous amounts of MONEY by bypassing existing trade routes and monopolies. The colonization was a byproduct.
I suppose a decent historical parallel is how the Dutch just made more land to farm instead of relying on colonial expansion. Oh sure, they had colonies, but those were about resource extraction for making said ridiculous amounts of MONEY rather than finding somewhere to live. Dutch colonialism wouldn't have worked without native populations to -enslave- offer minimum wage jobs to, while the polders were entirely homegrown.
Another might be the Boat People in SE Asia, where whole communities float on rafts/barges because it's a better use of resources than taking up land with homes.
Yes that sounds plausible to me, It’s how nature does things, kind of like diffusion.

Hello, let's assume that math is universal. My problem with communication with aliens is empathy, or rather intentionality.
In general, you need to know when someone is sending a signal or not. For instance we emit transmissions, heat and radiation into space all the time. And yet we send probes with special information for aliens. Sure, but how do they know what is part of the engine and what isn't?
We recieve Magnetic waves from space from time to time, but how would you know what is a message and what isn't.
And even worse is the language itself. It is very dependent on your content of everyday life.
Communicating with aliens wouldnt be like speaking to humans, talking to Animals or even to plants. It would be closer to trying to communicate with s rock, or sand.

How about videos on how various types of crystals form and how they can be so different from each others.
honestly, theyre all good islands. you dont go to a new star system for planets, you go for the giant, free fusion reactor
Honestly, I think aliens exist in this vast universe, but within my knowledge that we can't move faster than the speed of light, we probably won't be able to see aliens in our lives..😢
hopefully never if at all, or that we're the earliest sentient life in the galaxy. i understand why people would like to see non earth life atleast once but honestly if we come into contact with aliens that have nuclear fusion tech they'd transform our planet into a larger wetter moon in a few million years, even lesser should they have ftl and decide to chuck asteroids at us.

Well, sort of. The context in the video is of a more remote event. Would you want to go to war with somebody because you just recently received word about your great-grandfather's cause of death, might be more accurate.
Except that a lot of other stuff has happened in the meantime. It's never just about that.

One of the spookiest explanations for the Fermi paradox is that civilizations might create their own virtual universes to live in, instead of colonizing into space. Considering how hard humans are diving into the Internet and virtual reality, this sounds really plausible. Imagine a galaxy full of civilizations that live in computers, maintained by robots, living in a virtual "heaven" until the computers finally degrade and shut off.
Like a Matrioshka Brain?
Or the matrix
It's what makes more sense.
Send too much radio waves out, a biger civilization kills you.
Best plan to assure existence whould be.
1 Consume ALL ressources of the planet as much as possible so it lowers the chances of being taken over.
2 Hide every outgoing signal.
3 take brains, connect them to a computer almostnthe size of the planet.
4 encarnate into a simulation of the universe where we are alone and don't remember that there's a world outside this virtual world.
Seems pretty nice tbh
Pretty sure that will be the goal of AI for us. Much like The Matrix I suppose, but a bit less intentionally evil. It will love us as its creators and want the best for us, but will not tolerate us being in its way as there are so many of us and we are so antagonistic to anything that looks like it might disagree.

I feel like a lot of people overlook the time problem, especially with fermi’s paradox. The universe was extremely hostile to life forming planets up until very recently. We are probably one of the earlier planets that has been around long enough to develop intelligent life, and it is reasonable to think that other planets are also just breaking into interplanetary travel
You're close, but your final conclusion is seriously flawed.
Life has thrived in the galaxy for billions of years. Unless intelligent life is abundant (which is clearly isn't), it's extremely unlikely for two civilizations to form even within tens of millions of years of each other.
In other words, we are the only planet in the galaxy with such a civilization. Otherwise, you have to come up with absurd theories like the one in the video to explain why aliens haven't even been here, let alone colonized here.
@@TheFinalChaptersOR any more advanced civilization is so far away we can't detect them. Still, the result is the same, we won't contact aliens for thousands of years at best.

"Long enough", we have a single data point. We don't even know what the average "long enough" would need to be to expect to see intelligent life. There are a lot of factors that go into that, such as extinction events.
Kurzgesagt should make a video on human evolution. Itd be great to see it in their style.
Sometimes I like to think about all the incredible stories being writen right now by all people alive. It's amazing to think about all the lives going on in the universe.
It's fascinating to ponder the possibility of thousands of alien empires scattered throughout the Milky Way, each navigating the challenges of interstellar existence. The comparison to islands in an ocean paints a vivid picture of the vastness and complexity of our galaxy. It's a reminder that while we may feel isolated on our own "island" of Earth, there could be countless civilizations out there, each with its own story and struggles. The idea sparks both curiosity and humility, reminding us of the enormity of the cosmos and our place within it.
thats the biggest possibility. were a grain of salt in the universe, for all we know life could be a common thing throughout the whole universe

If there’s an extent to which interalien interaction is cooperative, it is a bad thing if we’re a remote island. Like how it’s hard per to win CIV V if you begin on your own continent while other civs trade tech
I think the biggest challenges for every civilization are going to be whether they evolve enough to even reach the stars or self-destruct before they accomplish that and to actually develop a technology make traveling between planets even possible within reasonable amounts of time (speed). I heard a theory before that a potential reason why no one has interacted with us yet is that every civilization that gets far enough in terms of development ends up at a point where it will self-destruct in one way or another which creates an endless cycle where species will always just be limited to their own immediate solar systems. I think it's possible but it would be a pretty negative outlook.
The other problem obviously is speed. Even light in terms of speed requires 8 minutes to get from the sun to our planet. No think about how many images we've seen from stars and other types of things in space that are light years away meaning it takes years at the speed of light to reach them. I think even reaching that barrier of making it possible to transport humans (or other living beings) at the speed of light safely from point A to point B is such a huge challenge that I'm not even sure if it's possible at all. Humans so far have managed to reach 39,937.7 km/h with the Apollo mission going to the moon. This is pretty far off from the 300.000 Km/s light travels in the vacuum of space. Also I think it's not just the speed itself but the acceleration and deceleration as well that humans need to survive with these speeds. Just considering this scientific barrier alone makes me question whether there are any species/civilizations out there that have managed to accomplish that. Without it there is no extensive exploration or colonization of space and I wouldn't even start talking about building any kind of empire out there because that requires to reach even higher levels of scientific development.
And if any civilization ever reaches that level we better hope that they have peaceful intentions if they come here because if they don't then we're royally screwed. No bacteria, infectious disease or computer virus would help us in that situation.

Assumptions lead to interesting ideas. Not to say interesting ideas can't come from ground truths, but assuming "what if...?" can lead you down many interesting roads, including many which end up leading somewhere.
Well said.
@@_ayohee or nowhere, because, it's easier to make popular videos for atheist NPCs than using scientific facts that strongly point towards that aliens do not exist and that humans will never colonize the solar system, let alone achieve interstellar travel
Kurzgesagt videos like this are supposed to be speculations
You had me at thinking machines.
_Looks at Serena Butler_
this is a weird question but I've been watching videos from your channel for quite some time and I'm even drinking tea from my in a nutshell mug as I'm typing this, but I just noticed that the alien language text that is used in this video and also in other ones actually has letters it replaces when it fades into English and that they're always the same letters, I was wondering if you guys had ever thought about making like a translation key for it or if its just something that there for the videos? if there is an image with all the corresponding symbols Id actually really love to see it as i often use things like that for painting minis or doing set pieces for DND
I like the idea that life is actually very common in the universe, but coincidentally not in our really dead galaxy or region.
or dark forest
Our galaxy doesnt have to be dead. Our radio signals have barely left a single arm of the milky way. So for everyone outside that arm, life here might maaaybe detectable by spectroscopy or something. Likewise there might be life all around us in the milky way, their signals might just not have reached us. Or when they do, there is no intelligent life here anymore, or none yet.
@@coolkid006"dark forest" usually has a darker implication, which is that civilizations are intentionally hiding because it's dangerous, not that they just don't wanna enter the forest.
I prefer an idea similar to this video but less optimistic from the start. "Rough Ocean" implies that intelligence is already common in the galaxy just isolated. I prefer "Arid Desert" existentially. Microbes are common. Large fauna are not. Intelligent technical fauna are extremely rare. Less than a dozen per Milky Way of stars. Asking for an excellent one capable of sending living members across interstellar distances for realistic profit on sensible time scales just isnt "reasonable". It's not. They're not common. At most, there could be a couple neighbors in the galaxy with machine drone explorers that can get around very quickly.
@@coda567i am of the belief that life is common, but intelligent life is exceptionally rare
kurzgesagt is one of those serious channel but also manage to sneak in jokes such as "its free realestate"
love them sm
The ''It's free real estate'' bar really caught me off guard. but that was hilarious to hear again
Why are alien civilisations always portrayed as biological ones rather than AI, which I find nearly infinitely more plausible considering our own progress
Ngl, watching these videos always gets me excited about space. Just imagining the fact that there could very well be beings which we’d call alive, going about their day or whatever their form of that concept of they even had it, right at this very moment. Just vibing or struggling like I am rn, and perhaps impossible to ever meet. It’s surreal
Same. It's a fascinating concept.
What about the decent chance of Aliens being here now? Those navy UFO sightings, Lazar, etc are pretty convincing
For their sake, I hope they don't know about Communism.
1. Survival is the primary need of civilization.
2. Civilization continuously grows and expands, but the total matter in the universe remains constant.
Which misses the entire point of this video mister three body problem.
@@ryans1632if the dark forest hypothesis is true, then it at least informs the point of the video right? The dark forest would imply that if there are other civilizations, they are probably hiding
We transform matter into humans mwahahaha.
not necesarilly true, because ther's also a sustainable way of life, and it's undoubtedly better for any civilization even if we are truly alone
The total matter in the universe may not be constant though, or "constant" in the sense that it's always infinite. But the extent of the universe which is currently seen as cosmic microwave background could literally keep going forever. And then there's the possibility of other material dimensions, individually distinct but connected universes, other quantum insanity, etc.... But with the size of the observable universe, there would never be a question of scarcity assuming it's all accessible anyways.
We can finally prove that Spore's space stage was somewhat accurate
Love This👽
The concept of the galaxy being an ocean with islands brings a different perspective to our understanding of the universe. I guess we just have to keep pondering and exploring the unknown patiently while hoping to find a good island someday.
We are standing on it.
The ocean is good when you are a fish.
Not a perfect analogy. The Polynesians did NOT have telescopes to scope the ocean with (would not work anyway due to curve of Earth) and see the islands from a distance even if they could not get every detail perfect but we have the technology even now to see other stars and exoplanets so a spacefaring civilization would have even better telescopes and other detection devices than we do. So space faring civilizations are not going at it quite as "blindly".
and we will destroy it
@@Zurround we can't see other islands neither, not their present at least. Alpha Centauri is +4 light years away, the system could have just exploded and no one would know for +4 years (being the closest to Earth btw). We are as blind as them if you ask me.
This made me realize one thing: We don't need to worry about alien invasions, the aliens are just waiting for us to terminate ourselves before settling.
wow platitudes
Trying to exterminate humanity is like trying to exterminate all the ants on Earth. We are one of, if not THE most populated mammals on Earth, 8 billion of us. We have technology allowing us to adapt easily. Not to mention, you only need a few hundred to repopulate Earth, that is nothing. Like, if you killed everyone on Earth except the city of Amersfoort, we would still have MORE THAN enough to repopulate Earth.
Maybe. Or maybe they terminated themselves first.
Aliens are watching us all the time
Or perhaps they've been around for millions of years, maybe longer. We might even owe them our existence.
I believe that colonizing planets by any alien is just extremely hard and practically impossible. For example, the nearest planet outside our solar system (Proxima Centauri b) is about 4.2 light years away from us. And right now, our fastest space craft is about 1/1675 the speed of light. That means that we would have to build a space ship that could fully sustain human life for 7035 years while not running out of power to even reach Proxima Centauri, which most likely could not even support human life. And that is THE CLOSEST plant.
whoever animates these videos should make a sci fi feature film.... PLEASE!!!!
The assumptions with aliens get me because they always assume if there are aliens they must be more technologically advanced than humans. Like why can’t they exist and we also just so happen to be the planet that’s the most advanced? Technically even bacteria on another planet would be considered an alien.
Well, we are assuming that intelligent aliens would be intelligent like us. In just a few hundred thousand years humans have gone from making stone tools to harnessing the power of the atom, our technology some would say has advanced exponentially.
Unless Humans are among the first intelligent life in the universe, one or two million years extra on humans, or in other words evolving 0.5% to 0.25% earlier in the life of the universe, would cause their technology to advance that much more exponentially to the point where interstellar travel is possible.
Any planet that has potential for life would have bacteria, we just want to find a species that is like us
it's a matter of scale and time. Even if an intelligent species evolved a mere million years before us, their technology should be a million years ahead of ours. Can you imagine what our tech will be like in a million years?
And all of this is considering only the tiny difference of a million years, what if they were a billion years ahead of us?
@@MrTuneslol See that’s what gets me, in a million years I imagine OUR tech could get pretty impressive, but I think its a bit of a stretch to assume the same would go for whatever form life took on another planet. Like I don’t doubt life of some form exists out there, but i think it’s probably much more likely it’s just some form of very resilient bacteria (most species on earth predate humans). I mean some planet has to be the top dog so why not us?
@@MrTuneslol Many people seem to lean toward aliens being more advanced than us, but, it isn't likely, based on available evidence. If there were any aliens out there, now, and ahead of us technologically, some form of electromagnetic radiation from them could be detectable by us, but we hear nothing. Why ? Quite possibly because we are the first, small G type yellow dwarf stars like ours aren't that common (~ 10 %) and are the best for life because they do not flare and are long lived and output sufficient energy to make a planets surface dynamic with variable energy strata. The other over riding factor is the age of the universe, it is YOUNG, as far as the "age of starlight" goes, which is at least 100 trillion years or so before the last stars fade into darkness, the statistical probability is obviously that the vast majority of the universes life forms have barely even begun.
People tend to forget that much of the universes early days were not friendly for life, the first generation of stars, the population three stars were no good because apart from Hydrogen, a little Helium and even less Lithium they were the ONLY elements around, most of the rest of the periodic table didn't show up after the next generation of stars, and seeding interstellar hydrogen gas with enough of these elements for the formation of rocky planets from proto-stars and their protoplanetary discs took billions of years. Given the se and other things that had to happen to get us here, it seems more than likely we are first, we may turn out to be the dominant life form across the entire galaxy, or even further.

Great vid as always. Small nitpick/comment/question: at 7:30 you mention unsustainability and self-destruction while showing an island with Moai, which I assume represents Easter Island(?).
This association (plus the sentence at 2:37 about "the human thing of ravaging natural resources") sounded like a reference to the theory of Rapa Nui people going extinct due to overextraction of their own resources on Easter Island.
I wanted to ask what you think of the debunking of this theory done in "Humankind: A Hopeful History" by Rutger Bregman, where the author claims that it was in fact contact with colonialist settlers which caused the end of the Rapa Nui, first through enslavement and later through disease transmission.
It wasn't the subject of the video, and there is no denying the human capacity for destruction of their environment, but I thought this specific image might be a bad example of the idea you were trying to get across, and might also entertain a false fact.
Thank you for telling me!
