> We also know for example that the types of beliefs detailed in Exodus, especially the idea that the Israelites worshiped Yahweh alone as the only God, are not historical. Belief and worship of other gods were common in both the ancient kingdoms of Israel and Judah long after the supposed time that the Exodus happened

I'm not sure what the point you're trying to make is. IIRC, that stuff is in the actual Bible. Like, a significant chunk of the Old Testament is about "Israelites [not] worship[ing] Yahweh alone as the only God."

This was not idolatry, as depicted in Exodus - this was full blown state religion, held in the same esteem as Yahweh, and co-existing with worship of him. So much so that El later became identified with Yahweh, and now most people reading the Bible (including Jewish people, Christians, and Muslims) believe El is just another one of Yahweh's names, or maybe the name of one of his angels.
