Origins of Jews/Judaism

by tjkool101

This is a question that I have researched quite a bit but I still feel like I haven't found a satisfactory answer. Are the Jews initially from Cannan? Is Cannan historically theirs? And I've seen evidence that Judaism was originally polytheistic, only becoming monotheistic much later on, is this true as well? I know that the story of Exodus is largely a myth, but is there historical evidence to suggest that Jews migrated to Egypt? And when did the history of the Jewish diaspora truly begin?

I suggest asking this at r/Judaism where there are people who well versed in Jewish history.
