Moses never existed … or if he did, he was only a minor historical character and most of his life was expanded by legend.
When I was an atheist I believed Moses never existed. The Jews made him up to bolster their religion. However, if someone by the name of Moses really did live he wasn’t anything like the stories about him in the Bible. No way he called down the wrath of God on the Egyptians. No way Moses raised his hands in the air and a sea of water split in two. No way.
I used the story of Moses leading Israel out of Egypt as a major proof that the Bible was full of myths and fairy tales. It was a favorite discussion on my radio talk shows in the late 1960s and early 70s. Adam and Eve, Noah and the Flood, Abraham leaving Ur for Canaan, Joseph in Egypt, and Moses leading Israel out of Egypt were stories I threw at Christians whenever they called about the Bible and Christianity being true. There was absolutely no evidence for any of those stories, so why should I believe anything in the Bible. Everything in the Bible was untrue.
That worked pretty well until I met some Christian apologists. They answered my mocking and skepticism with evidence … lots of evidence … so much evidence that I was no longer able to say the Bible was full of myth, fairy tales and lies. I didn’t know where the investigation would lead me, but I knew there was more to the Bible than I thought.
The archaeological finds I had already seen were impressive in supporting some of the historic nature of Genesis. What would I find in archaeology to support the historic nature of the “Exodus?”
