Nice parallels to Eve & the Serpent/Satan.
Most if not all native american tribes have the flood story.
Southwest tribes (and probably more) have some version of the “white painted lady”, who, when mankind was being threatened by a great serpent, gave birth to a son who crushed the head of the serpent with a rock.
Both those seem to be echoes of what is in Genesis, passed down orally through many generations (and implying a common human descent).
