Adam was a short beast, with a thin line of hair down his back, like a mane. Eve had a thin line of hair down her back; it was like a mane.
In those days, when you came into town, a stranger, you could always recognize Adam and Eve, because they were the only ones without navels.
The first writing was by Cain, who started by drawing pictures on his parents' bellies. Their bellies were smooth, and had no navels. Cain would ask them to lie back by the fire, and close their eyes, and he would draw. When he was done, they would open their eyes and look at what he had drawn.
Once Cain drew an unheard of thing. It was such a thing, that when God saw it, he let it stay on Eve's belly as punishment. God punished Eve for the evil sport she had fallen into. It could not be washed away, but stayed on Eve's belly. For they had fallen into an evil sport.
