Archaeology shows idols in Cannan up to the Babylonian exile.  None after the return. The Exile is also where the Law books of the Torah were probably consolidated.  They were not written by Moses and there were only few in the party that left Egypt, went to Horeb (not Sinai) - where the 12 pillars were found, and then went to Israel, which was not overcome in any sense.  Of course, the anti-Modernists blanch at all that.  They have their right to be wrong, but not to insist that their error is the only Truth.
