Wow. This seems to be supporting Ruth Beechick's ideas in World History Made Simple. She has the Egyptian timeline tied in to occurences of God's wrath. If I remember correctly this one was the destruction of Sodom and Gomorrah, which caused Africa's Great Rift.
The work done by these two seems completely independent of studies of axis tilt, with instead a tie in to meteors and not a flood.
I am reading this thread with fascination and very little understanding.
