The Why Files came out with an interesting video a few days ago:
Göbekli Tepe and the Prophecy of Pillar 43 | Apocalypse and the Vulture Stone
In this video, AJ describes the evidence both for very ancient civilization at sites in Turkey like Gobekli Tepe - and for the destruction of civilization around 12,887 years ago. (Boy that's close to the 12,900 years ago I've been suggesting for the last pole shift catastrophe!) AJ is focused on comet impact, but what he describes seems like a pole shift caused by such an impact. Either way, you get earthquakes, volcanoes, megatsunamis, climate change, and the end of civilization - and he repeatedly hints that it could happen again soon, possibly within "twenty years."
