Both the Earth and the Moon have been hit many times throughout their long 4.5 billion year history. Once something hits the Moon, that event becomes frozen in time. Earth, on the other hand, brushes these impact craters off and moves on with its life.
That’s the reason there are so many craters on the Moon compared to Earth! What’s more, their formation and evolution record the history of the inner Solar System.
