I doubt Moses was an actual historic figure, if the God of Moses had actually drowned to death the Egyptian army and cursed all of the Egyptian firstborn sons out of existence, then I suppose this should have been noticed by Egypt's adversaries who would have likely then conquered Egypt. Please allow me to posit the writer of Genesis as having intuitively known the Earth's soil must have existed before the vegetation that sprouted from the Earth's soil.
The dating of the Exodus is a real mess archaeologically and most archaeologists want to date it to 1250 approx when there was no Jericho to conquer and the archaeology of Canaan does not fit the conquest story in the Bible. Yes I agree,,,,,,,,,,,,insane.
The Biblical date for the Exodus is about 1450 BC and Jericho was there and the archaeology of Canaan for a 1450 Exodus fits the conquest story in the Bible.
That date makes more sense to me.
However, in stead of making more sense it seems it is easier to say the Bible is wrong and that there was no conquest.
Depending on the dating you choose, the Egyptians can be seen to have been conquered shortly after the Exodus and/or be weak and unable to maintain their kingdom. But as I say, the archaeology is a mess and different theories abound.
