Nice points crazy, I believe that you're on to something for sure. Outside of scriptures & history, this can be considered With Logic & Reason alone.
The God that created the Universe, is a God of Order, when he sets one law in place, he does not at a later time scrap that law, and replace it. If this God were to change principles in nature, because he was emotional or mad.. The Universe would fall apart..
Wih this Unchangeable nature in Mind.. Things like this can't happen - Prov 12:10 "Whoever is righteous has regard for the life of his beast, but the mercy of the wicked is cruel." Compared to Joshua 11:6 "Joshua did to them as the LORD had directed: He hamstrung their horses and burned their chariots."
I don't know when and where the different Gods interchange, however it seems to be a sure thing, that there were many or several Gods. Another forum member, recently brought this to my attention- "Stephen, the first martry, quoted someting in Isaiah about when Israel wandered for 40 years they weren't following God but following a different one and his star."
