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.
If you want another good Youtube channel about ancient civilizations, and proving the mainstream historical narrative wrong, there's one called Uncharted X.
It's run by an amateur, but he researches this stuff a lot, even goes to the sites quite a bit. He has both long and short form content, but all of it is great. He mostly focuses on Egypt, but discusses other areas as well, like central and south America. He has lots of really good evidence, in picture and video format, of saw marks, tube drills, massive lathes, scoops marks, and other advanced machinery which produced perfectly symmetrical and repeatable stone works, both massive and incredibly small and intricate, some of which is even impossible to reproduce with modern machinery (i.e. tube drill marks digging into stone much faster than we can).
He also discusses the debunks the absurdity of the mainstream historical account of how those ancient stone works were made. He also has interviews with Randall Carlson, discusses the Younger Dryas impacts, the evidence for worldwide floods, and delves into the clear possibilities of ancient civilizations. Great channel.
