Actually i tend to beleive what the Egyptians wrote. They saw a star brightenening in the sky, the peiests went nuts because it had to be one of the gods coming, and he didn't look at all happy. Then as the star drew brighter, earthquakes and floods. The priests really freaked. Then it settled into orbit. I give you our moon. This is probably the single greatest account of our moon being a rogue that got caught in the earth's gravitational pull. It's all there, in Heiroglyphics.
Ever wonder if it's in a slowly decaying orbit? And no one has bothered to tell us?
