Or....Moses didn't exist at all, and there was no captivity in Egypt, no Exodus, and no conquest of Canaan, nor of a united kingdom of Israel and Judah as described in the OT.  There is no evidence for any of this.  It is more likely that it was written in the 7th-6th century BC for political purposes, drawing on earlier tales/myths and dim memories (e.g., expulsion of the Hyksos) in an oral tradition.
