Did Moses see God’s face?

Ex. 33:11 tells us that God spoke to Moses face to face, as a man speakers unto his friend.
In Ex. 33:20 God tells Moses, Thou canst not see my face: for there shall no man see me, and live.
So one verse says they spoke face to face and the other says that no man can see God and live.
It appears to be a contradiction. Let’s get into this study.
