She didn't see him again until Spring. He came back.
He became Reindeer Man and she became Herb Woman. The kids grew up to be the Human Beings.
This is an authentic Ice Age story far older than 10,000 years. The next story in the line up is about the mother with two daughters. She told her man to take them someplace to find husbands for the girls.
He took them to a town where all the men were homosexual. They preferred even visiting Reindeer spirits. Eventually the town was destroyed by ice and the woman and her family fled into the wilderness.
Obviously she couldn't find any husbands for the daughters so she turned into stone. Her husband then slept with the daughters and got them pregnant.
There are some other really, really, really old stories from the Good Old Days when the Sa'ami ruled the North.
That last story sounds a lot like Lott. Very similar!
I plan to go with whatever creation myth the people of Lemuria (or Mu) had. They actually experienced great floods.
