Its a shame that a lack of hard evidence and a disdain for looking for more from theological groups resisting demystifying their religion means we don't know or have records on a lot of the early days of poly to mono theism.

Considering it looks like the 18th Dynasty of Egypt had a push to move away from Poly in Amun that involved building a new captial with the help of skilled laborers from the North Canaanites only to be be attacked for their position by the older poly religious leaders causing the downfall off the new capital falling and the workers fleeing back across the desert...

I mean there is so much to piece together of how politics and the empires of the time influenced how we as humans and religions developed but then you might ruin the idea of magic with real world incredible stories.
