Also in jewish tradition God was first named El (by Arbraham and progeny), but would demand to be called YHWH (I prefer this form as the real pronunciation isn't known) from Moses onwards.

Historically it is more likely however that the stories in which God was named El, date back before monolatrous and/or monotheistic Yahwenism and are part from the earlier and encompassing Canaanite religious traditions and culture. (Cfr. the very recent discovery of a much earlier Ugaritic version of the story of Adam and Eve). El was the deity that headed the Canaanite pantheon.
