Explain the importance of the Kuiper Belt to a second grader

The best indication of the significance of the Kuiper belt lies in its multiple connections to other aspects of the Solar system. The dust in the Zodiacal cloud, the rocks in the meteor streams, the nuclei of comets, the Centaurs, perhaps also the irregular moons of the planets and the Trojans that lead and trail planets in their orbits, are all related to the parent population in the Kuiper belt. Further afield, the dusty debris disks of other stars are likely produced by collisional shattering of parent bodies in unseen Kuiper belts about them. Because of these many connections, Kuiper belt science has already had significant impact on the study of the contents, origin and evolution of the Solar system, and on understanding the Solar system in the context set by other stars.
