Interestingly done - recommend David Rohl's Legend:The Genesis of Civilization - you must understand that the first chapter of Genesis is a 5th century BC document essentially borrowing the story from the Babylonians - it ends ant Ch. 2 v. 4a. Then begins a different story, much older, primitive, which probably contains some Oral History - These two strains persist throughout the old testament - two flood myths, two histories of David etc - The first chapter uses the word "Elohim" for "God"; the second chapter, the scholars (and this goes way, way back) use LORD God for the term "Yahweh" - different characteristics, differing viewpoints - the bit about the "sons of God" is absolutely borrowed from the Babylonian and Akkadian texts - many of which have only begun to come to light in the last 20 years - see Rohl's book for an update.
