I really enjoyed exploring the take of Adam and Eve being figurative story about the transition from childhood to adulthood. It makes perfect sense to me. We see so much metaphorical writing in the Bible, with stories like Jonah that are also outlandish to the modern mind, which make this story seem manufactured to tell humans a story. I also don’t think that this new meaning nullifies the creation story aspect of it either as double entendres exist for a reason, to make you think. I think there are things to learn for humans both ways you perceive it.
In regards to the Pentateuch and its writers, I think there is no way that it is not multiple writers. All the inconsistencies in the writing styles proves that it wasn’t Moses solely. There is no real reason for Moses to have this inconsistencies, that he must’ve consciously chosen to make. Even if at one point in time Moses did “write” all the stories, there was most certainly somethings that were lost in translation as the Pentateuch was formed after his death. Therefore even if it did originate from his mind it has been warped into something else, shown by the inconsistencies in his writing.
