Anybody who imagines that revealed religion requires a craven clinging to a fixed, unalterable, and self-evident truth should read the rabbis. Midras… - Karen Armstrong

When Adam and Eve were expelled from the Garden of Eden, they probably did not fall into a state of original sin, as Saint Augustine believed, but into an agrarian economy.

The one and only test of a valid religious idea, doctrinal statement, spiritual experience, or devotional practice was that it must lead directly to practical compassion. If your understanding of the divine made you kinder, more empathetic, and impelled you to express this sympathy in concrete acts of loving-kindness, this was good theology. But if your notion of God made you unkind, belligerent, cruel, or self-righteous, or if it led you to kill in God's name, it was bad theology. Compassion was the litmus test for the prophets of Israel, for the rabbis of the Talmud, for Jesus, for Paul, and for Muhammad, not to mention Confucius, Lao-tsu, the Buddha, or the sages of the Upanishads.

The cosmology of the ancient world was telling you about the nature of life here and now. Genesis is not about the origins of life. There were many other creation stories current in Israel at that time and no one was required to believe in that one.
