Not to disagree with you Doug Mason, but I thought that the origins of Yahweh were from the Sumerian god Enki?
There are many bible stories which have direct correlations with Enki's mythology, (And with the Sumerians predating the Israelites and the Canaanites and being a major power in the region their religion is likely to have had an influence on both) for example:
Enki is the creator of man.
He is a flood god.
He confused the tongues of men, creating all the different languages.
Also, reading the Wiki entry on him just now, I noticed that Enki is depicted with two streams of water flowing into each of his shoulders: one the Tigris, the other the Euphrates.[12] Alongside him are two trees, symbolizing the male and female aspects of nature.
I might be reaching too far here, but that sounds a lot like major elements from the garden of Eden story to me.
I've just read this bit in the Influence section of that Wiki page:
As Ea, Enki had a wide influence outside of Sumer, being equated with El (at Ugarit) and possibly Yah (at Ebla) in the Canaanite 'ilhm pantheon,
So, yes, it looks like Enki became Ea and then became El. So... we're both right? :)
