The Man in the Moon may be more real than you think. "The Moon is occupied by various ET races. They brought the Moon here many moons ago to stabilize the climate of the plantet." Wax on, wax off, or so they say. "The waxing and waning of the Moon keep the tides consistent, and the weather patterns consistent. Our weather wouldn't be accomodating to agriculture like it is now. The seasons would be much less stable and coherant, and inclimate weather would have limited our potential to grow as humans, by a lot."
