"This is extremely significant. Knowing something of when the Pentateuch came to be, even generally, affects our understanding of why it was produced in the first place--which is the entire reason why we are dipping our toes into this otherwise esoteric pool of Old Testament studies. The final form of the creation story in Genesis (along with the rest of the Pentateuch) reflects the concerns of the community that produced it: postexilic Israelites who had experienced God's rejection in Babylon. The Genesis creation narrative we have in our Bibles today, although surely rooted in much older material, was shaped as a theological response to Israel's national crisis of exile. These stories were not written to speak of "origins" as we might think of them today (in a natural-science sense). They were written to say something of God and Israel's place in the world as God's chosen people."
