He's so dead set on the fake-news evidence of Israel leaving in the 1200s cuz that suits his narrative. Folks like him were all the rage back when the classic 10 Commandments (who presumes Ramses' son was king during the Exodus) was made. I tried to outline why their claims are so bogus, in
http://www.brainout.net/Exodate.htm .
But now think differently, especially since we have the Cleopatra steles in NYC and Britain, how Moses was Pharaoh then called himself Thutmose III, his scarabs being all over the Levant. By contrast, Amenhotep II was the Pharaoh of the Exodus, had only 9 campaigns all ending 1441 or so BC (right on time). The Greeks invented the name Red Sea for the Reed Sea (Yam Suph, in Bible), Herodotus being a key writer of that, DUE TO Pharaoh drowning.
In short, our boy here claims no evidence of the Exodus and if it happened, it conveniently happens when he needs it to happen.
Yet think: if it happened in 1440, that would TRIGGER the very process he hypothesizes. It would take a century or two in order to finish, Israel the meantime growing stronger and a real breaker of powers in the region.. just like Bible says.
So what helps prove the process this guy poses is done by a nation this guy doesn't want to then exist as a trigger. Oh well. Which process, the book of Judges covers, and Psalm 90 outlined it (one syllable per year, dual use of the Psalm).
