For a couple of decades the Government of Israel has funded research to establish that Jews fled Egypt, lived in the dessert and then defeated the evil Canaanites. The fortune spent looking for evidence of this has yielded nothing. This does not “prove” the story is completely fabricated. It leaves us speculating why there is no evidence. An attractive conclusion is none of it happened.
One thing found through archaeology is a Canaan society that left no pig bones in its garbage, abruptly left the lowlands and moved to hill tops. That is the single best evidence of the early Jews. Anthropological theory would suggest they grew out of an ancient Canaan culture.
One theory as to why they moved to the hilltops is that the Philistines, sea people, began to move into the area and mix with the locals. Perhaps Jewish leaders did not like such people and off they went to more defensible high ground positions.
This theory, however, provides no information as to the source of a monolithic faith in a world that worshiped multiple gods. It also sets aside a great question among Jews themselves as to whether being a Jew is about religion or about a nationalistic cultural identity.
One part of the “top of the mountain” Jews evidence is that the Jewish faith/culture came about over a long period of time. This is different from the Biblical theory of a scolding Moses who quickly set out the rules for Jews.
