In my astronomy class, my teacher said some say billions of years ago, some big asteroid hit earth and made a big hole in earth, so big, that the piece of earth was being separated from earth, but end up orbiting earth, and over the years it cooled down, and that's how the moon was formed. They said, some parts of the moon looked like it WAS full of "volcanic or molten rock" because some looked like a spot of smooth surface except right in the center, it was a thin straight rock, or small or "mini-mountain". What's your opinion?
