This a a bunch of crap!!!
What would have happened to Earth's rotation on its axis had it had another moon? It would have been disastrous causing wobbling on its axis, which in turn could have been catastrophic. It is a fact that Earth’s moon helps life on this planet because its gravitational pull which in turn prevents the earth from wobbling around too much on its axis. To sustain life on earth an exact combination of the right distance between sun and earth as well as a moon of the right size—and this on top of all the other considerations regarding the nature of the sun-are needed. I guess the experts are gonna be saying now, that if the other moon were still there no life would have appeared on Earth?
