I am not sure what would be the best POD, so maybe you could suggest it in your reply. The Tanakh (which Christians call the Old Testament) was yet not fully written, so I refer to the religion as Proto-Judaism at this point. The religion was influenced by the Babylonian captivity. The story about the flood was taken from Gilgamesh, the story about Moses' childhood from the story about Sargon of Akkad's childhood and the idea about a Messiah from Persian religion. It has also been suggested that the whole story about the Egyptian captivity was invented and inspired by the Babylonian captivity. If so, is it possible that the religion could develop in quite a different direction?
