“There is no evidence of any mass Exodus from Egypt, or that Hebrews ever lived in Egypt.”
And actually quite a bit of “evidence” that Moses was in fact an Egyptian prince, a monotheist and no more a Jew than I am.
Correct. Monotheism was established as part of the ancient Egyptian belief. The Semitic word Adonai reflects the name of the Egyptian pharaoh who established monotheism in Egypt.
Moses is an expressly ancient Egyptian name. If he had been rescued as an infant and raised as an Egyptian, he would not have known he was a Hebrew.
The story of his birth, including the basket and how it was sealed with tar when it was sent down the river is almost verbatim spelled out in Babylonian mythology, just as the story of the big flood, and many other OT stories.
