According to me, of course. And up to now, of course. I’ve just finished reading Mark Smith’s The Origin of Biblical Monotheism. Amazing. A real masterpiece. In pre-exilic era, Smith recognizes Asherah worship, infant sacrifice, solar veneration, while monotheism was a late development in the Babylonian Exile. Smith concludes that Israel’s monotheism was heir and reaction to a long tradition of Israelite polytheism. He extensively quotes from Ugarit original sources to reveal common features of Yahweh and El

In short, if you want to understand how Israelites invented their (and Christian’s) Yahweh you must read this superb book.
