Did you sleep through OT History in high school? Everyone knows that the Eden story is mythical, as is the creation account, and that they were adapted by the Jahwist writer, probably in 1000 BC in the Court of Soloman from Sumeric source material. They were further edited in Babylon during the exile. All of Genesis and Exodus is like that, not the Charleston Heston version-only one village left Egypt in the Exodus, not a nation and they went to Horeb, not Saini. The twelve pillars and altar were found and no evidence of a large permanent camp. The rest of Torah was done during the exile in order to have a law when they returned. Read Nehimiah which confirms how the law was accepted. Archeology confirms that prior to the exile, Judaism did not dominate the national religious life. Other gods were worshiped.
