Why Are There So Many Cratered Moons?

Imagine playing a game where you throw rocks at your friend's toy house. Every time someone throws a rock, part of the house breaks and gets a new dent or hole. Our moons are like that toy house, they get hit by lots of space rocks over millions of years. Each time one hits, it makes a crater, which is kind of like a dent on the moon's surface.
