No-one actually believes it, but it is a nice little story that an intergalactic otter (of course) was swimming along in nothingness, when a fish leaped out of nowhere (literally) and she caught it. The otter sliced the fish open, ate the meat, and with the bones, created the universe. The eyes are black holes, and life is thought to the the devoured fish entrails.
Yes, that's right. In Garbelia, the creation myth has life being fish insides. That is where the saying "Life is the fish intestine of the galaxy." comes from.
