Almost the entire Solar System formed 4.6 billion years ago, when the solar nebula collapsed. But astronomers think that the Moon formed later than that, when a Mars-sized protoplanet smashed into the Earth. The debris from the collision splashed into orbit around the Earth and then reformed into the Moon, which still orbits us today. Astronomers think this collision happened about 4.53 billion years ago, about 30-50 million years after the rest of the Solar System formed. This was relatively soon after the formation of the Solar System, and well before the time when life formed on Earth. Our planet was probably still mostly a molten ball of rock, and the impact of the Moon did little to change that. This is the dominant theory of how the Moon formed, but there are others. Its possible that the Moon was captured by the Earths gravity, or it just formed in place around the Earth after the formation of the Solar System.
