Luna, how do you deal with the contradiction in God's opinion of humanity between Creation 1 and Creation 2? I am surely not the first to notice this discrepancy as it provided fuel for much of the Gnostic rebellion against Yahweh. Ignoring the differences does nothing to make them go away.
I think the basic premise of the documentary hypothesis makes sense. Genesis 1 is a very sophisticaed Creation account written during the priestly era, densely packed with a theology by which God is Creator of all and Israel is His chosen people.
Going by some notes I have on-hand (because I am not a scholar), theological points are 1) Dualism is rejected, God is both transcendant and immanent, Nature acts as God created it to act, and humans respond from their own God-given freedom, Creation is fertile by the gift of God, Humanity is in the image of God, "Man" included woman, and human beings are God's representatives.
Genesis 2 is an older creation story, also tightly packed. It tells the story of creation and also 'explains' sin in the world (the Fall), the tragic alienation between God and man, and between man and man.
Two stories written at different times with different emphasis. There are many redundancies and contradictions in the Bible, not just in Geneisis. The editors were not so much concerned with reconciling and smoothing out the discrepancies (as our Western-trained, post-enlightenment minds might be inclined to do), but with telling and recording the depth and breadth of their understanding of God.
If I were versed in Jewish oral tradition, perhaps I would see this very differently.
Anyway, I do not see a contradiction in God's view of humanity between Gen 1 and Gen 2. I see a story of a relationship that started out perfect, and then mistrust entered in on the part of people.
