One could as well argue that because they took the hits, life thrived on Earth. As in, chance, again.
Actually, the moon didn't 'take' any hits for Earth. Earth has been pummeled just as many time (and probably more) than the moon has.The moon only looks worse because it doesn't have enough mass to generate the gravity necessary to create an atmosphere of wind and rain like earth.
The moon's scars are there forever. Earth's scars have been smoothed over and covered up by centuries of erosion caused by wind, rain and vegetation.
Yes, I had mentioned that the Earth is not spectacularly lucky from asteroid impacts, earlier on.
If the things line up in a particular way, the Earth WILL take hits.
