Some speculate this based on a found translation of Duet 32:8. But one problem with this idea is Yahweh is described just like El. But there is some evidence that the God Elyon was a God above the God El and not El himself. Anyway it's hard to tell for sure since every city or community may have their Pantheon of Gods be just a bit different then another community. Another problem is names could altogether change, Baal had different names, and at times one can't tell if they we're refuring to the same God. Another thought is that yhwh wasn't actually refuring to one God but a family of gods. El,Ashurah, Baal,Anat for example.
One other thought I have had recently is about the goddess Anat. She is never mentioned in the Bible but almost all the other top gods of the Canaanites are. She is a war God, so I'm wondering if maybe Yahweh isnt some form of her. Her name is mentioned in a Jewish stronghold in Egypt in a letter as Anat-Yahu. Just a thought but we find this kind of thing in Egypt where a God is an aspect of another God. Amen become one with Ra so does Atum and a couple of other Egyptian gods.
