Our planet has no craters because there is water flowing; there is erosion; there is wind, This makes it impossible for us to know how frequently the Earth was bombarded from space when life on this planet was just beginning. In this video segment, hear about scientists who are impatiently waiting for astronauts to return to the moon because they think it may hold clues about the beginnings of life on Earth. Because the moon was in the same path of colliding debris and doesn't suffer erosion, its many craters may serve as a record of what came our way.
