No one was around at the time, so we're not really sure, but the current hypothesis in favor is called the "Giant Impact Hypothesis."

It posits that a protoplanet about the same size as the current planet Mars struck the proto-Earth while it was still forming, and "splashed" a lot of rock off. This eventually formed the Moon, while the rest of this protoplanet (named Theia) joined with the Earth.
