There are collisions between asteroids, which can knock asteroids and asteroid fragments into different orbits. Some asteroids may not have originated in the asteroid belt.
from animals
Scientist say that a large sum of asteroids did a big bang and the asteroids created the lava core in the center of the Earth, when the Earth spun the heat cooled down so that bits of rock and environment could form. So according to scientist asteroids created Earth. Basically he means that earth was made from rock
Yes, it is commonly thought the moons originated as asteroids, pulled from the belt by gravity.
Pangea
In the asteroid belt, as well as in the rings of some of the gas giants.
