Could the Abrahamic God been imputed as having been another deity?

Sumerians had many deities, but as time progressed so did the system. The Akkadians, followed by Babylonians carried over these deities and renamed some. Could any (particularly Enlil) have been associated with being YHWH regardless of the concurrent changes thereafter? “Abraham” was allegedly from Ur in Sumer and therefore was a polytheist prior to being spiritually engaged by God. Could Abraham taken a Sumerian deity with him from the age of 1900–1600 BCE as the foundation of the Hebrew and Jewish creation? Is this perhaps why Jewish creation was renewed upon arrival at Canaan? I’m mind mapping here. Throw some bones and please be courteous.
