Without our moon (are we the only planet with just one?) we likely would not be here. Winds and raging oceans would not have allowed life to exist on earth. It is perfectly placed, sized and massive to benefit us.
There are theoretically billions of of earth sized planets at just the right distance from their suns to be compatible to us, but without that perfectly placed moon, that number shrinks.
We are chosen, by God, to be here on this place. He has selected us or allowed us to be through it. The moon is an integral part of our success.
