Saturns Rings: Longer History Than Believed?

Recently, scientists have discovered that the rings on Saturn have existed longer then scientists have previously thought. The rings just may be as old as the solar system. Previously, in the 1970's, they had believed that the rings were around for a hundred million years. Their previous prediction was the rings formed in leftovers from a meteoric collision with the moon. Their prediction was based on the 1970's voyagers. Although, the most recent space probe shows that they were created almost 4.5 billion years ago! That's almost the same time that the sun and the planets formed! Also, the space probe (Cassini) discovered that rings are constantly breaking and re-building themselves. That must be a lot of work!
There are seven main rings on Saturn. There are also many, many ringlets. They are made with orbiting ice combined with dust and rock bits.
