Why does Saturn have rings?

Is it because of a property of Saturn or an event that caused it to have rings?

Also, why doesn't the matter in the rings clump together to form moons?

All of the gas giants have rings. It's a property of heavy planets. Think of rings as failed moons that have been ripped apart instead of coalescing because they are too close to the planet.  


If a moon suddenly appeared in orbit in the ring, then the side of the Moon nearest the planet would want to orbit faster than the side of the Moon farthest, and it would get smeared into a ring. This effect still occurs farther out, just not as severe. This is why some moons of Saturn and Jupiter have crazy volcanic activity.
