At one point in a past before our past, the great gods were jesting and boasting in heaven, each saying he was the best. One spoke up and said, "I know how we can know this". He reached down to the earth, a pile of clay, and began to mold a shape. "I say my creation is better than yours, therefore, I am the best". In turn, each god made his own creation, and they set them upon the clay they were made from. But still, there was no way to decide. The first spoke up again, "Fine, we shall have them battle to survive, we shall know the best from who the last creation is".
