Between about 4 and 4.5 billion years ago the solar system was rather chaotic. There were many more asteroids and planetoids with unstable orbits. As a result collisions were much more common in the early solar system. Since then most objects with unstable orbits either collided with planets and moons or with the sun or were ejected from the solar system.
