The idea of all humans originating from one single human pair was a brilliant insight not found in all cultures.
To which I replied:
The idea of all humans coming from a single human pair is firstly scientifically wrong, and secondly found in most mythologies. I'm at a loss as to recall one that doesn't have a first couple from Odin making Ask and Embla out of driftwood to the Navajo myth of the insect people traveling to the fifth world and making the first man and woman or the Apache myth of creator making Girl Without Parents and Small Boy out of dirt from his hands rubbing together into clumps.
I really am at a loss here. Is there any mythology that doesn't start with a first couple? Does anybody know of a creation story that doesn't explain the first couple but the first group of humans larger than two or something that would qualify as not a first two humans story?
