We will accidentally blow up the moon while trying to excavate it for human living. It will cause the tides to go haywire and some will be forced to go subterrainian while other will try to survive on the surface. Both species will evolve on their own into seperate races. The subspecies will develop into animal like cannibalistic creatures because of the lack of a food source below. They will wipe out the surface dwellers and will become the surviving race. One day one of the creatures will uncover a highly modified 3.0 Contour SVT. He will use it to make toothpicks and hammers.
