"...HYPOTHESIS III. The Moon came into being separately, and, moreover, far from the Earth (perhaps even outside the Solar system). This would mean that the moon would not have to be fashioned from the same "clay" as our own planet. Sailing through the Universe, the Moon came into Earth's proximity, and by a complex interplay of forces of gravity was brought within a geocentric orbit, very close to circular. But a catch of this kind is virtually impossible.

In fact, scientists studying the origin of the Universe today have no acceptable theory to explain how the Earth-Moon system came into being..."

could this be how the Moon is locked to Earth orbit... with spinning on it's own axis...
