Having scanned a percentage of the 643 posts I am suprised if no other comparative documents than deerbreh's have been quoted in the debate. Correct me if I missed any.
In 1970 I devoured a book which explored the Exodus as part of a GLOBAL catastrophe. In it documents and documented legends, etc point to nations all around the world suffering similar events to the Egyptian plagues, followed by periods of intense darkness, famine and re-location.
There is a huge list from which I will quote a few instances:
Ex 7:20 "..all the water was changed into blood."
Ipuwer Papyrus: "The River is blood.."
Mayans: "..earth quaked, river water turned to blood.."
Ex 9:23 "..Lord sent thunder and 'hail' (Heb 'stones of barad' - meteorites) and lightning flashed down to the ground."
Ipuwer: "There was fire mingled with hail very grievous such as there was none like it in all the land of Egypt"
".. trees destroyed, grain perished..like cutting flax.."
".gates and columns consumed by fire"
Ex 24:23-28 ". Pharoah's horse and chariots.."
Ipuwer: "His Majesty fought with the evil-doers in the whirlpool. His Majesty leapt into the place of the whirlpool."
And that's before I get onto pole reversal, prolonged darkness, ambrosia (manna = 'honey') and rivers of honey.
So something BIG definitely happened. So big, that geological changes could well have changed the face of the world. Hence our Red Sea crossing will be even more difficult to establish!
