Imagine if you will earth with not one but two moons.
Some are certain that such was the case up around sixty-five million years ago.
Now imagine if we had two moons and one of them fell.
Would such an impact shatter the earth into plates?
Would not the subsequent fall of water and nuclear winter that would ensue change the face of the earth forever?
Take out a map of the world and focus on the Pacific Ocean.
Theoretically, if such a moon fell, and it came in from the southwest, would not the Pacific Ocean be the crater of such a fall?
Think about it!
