Supposedly there is this documentary on Netflix that shows some good evidence that an advanced Atlantis type civilization was destroyed in about 13,000 BC by a comet or something like that. This would push back human civilization from the hunter/gatherer stage back quite a bit, since most anthropologists say civilization as we know it started about 4,000 BC (even though sites in Turkey already show that is wrong).
This documentary has all the experts class people riled up about his apparently popular Netflix show. On Twitter, I see Bible believers of one stripe or another saying it's evidence for a flood type event from Genesis, which exists is most cultures' mythology. This may or may not be the case. Atlantis is a popular idea too, and the Atlanteans may have spread civilization out to the hunter/gatherers after the loss of their homeland in the flood.
I intend to watch it this weekend. Here's an article on it.
I just wanted to say thank you for making this post, OP, because now I have all these other leads to follow. I didn't know this subject was becoming popular and all my sources are really old news, a ie Rudolph Steiner, Dolores Cannon type folks.
