I very much respect your opinion, so could you let me know your response to my reply below:
There is much text in the Bible to show there superiority of God over the gods of the surrounding nations, for example, the Egyptian plagues were designed to show the superiority of God over the Egyptian gods, so this text in Genesis may have the same purpose.
With regard to Babylonian traditions being the source for Genesis, I would reference the work of Yehezkel Kaufman who stated “monotheism cannot evolve from polytheism as they are based on radically different world views.” There are similarities in form of worship, but the basic principle is quite different (the number of gods is actually irrelevant) The primary difference is that in all forms of polytheism, there is a Metadivine realm (MR) to which the gods are subject, they are born from the MR, they can die, and power is materially achieved through that which comes from the MR. Humans can tap into the MR through the use of “magic” to protect themselves from the gods, help a particular god or gain control over a god. The gods are both good and bad.
In contrast, the religion of Israel had a God that was the source of all creation, outside the metadivine realm and is only good. Humans, through service and faith, can have fellowship and blessing from God.
This is a radical break from polytheism, so what would be the source of this monotheistic approach?
