..can someone explain to me why the rings are flat instead of doughnut shaped.
Saturn's rings have been knocking around the galaxy since around the time our Solar System was born, NASA's Cassini spacecraft has shown. Though not in ring form the whole time, obviously.

Assume they were thicker - the particles outside the equatorial plane would have to cross it twice an orbit; they cannot just stay on one side. As a result, such particles would pass through the thicker bits twice an orbit, and drag from gasses and dust (and collisions with larger than dust sized objects) would eventually remove the "up and down" part of their orbital velocity, leaving them in the equatorial plane.
That's why the major palnetary bodies *generally* orbit in the same plane, there is currently more variation in orbital inclination as there is much more space to play in, and thus takes a lot longer for the collisions to create a truly flat ecliptic plane. The principle is the same though.
I agree, God created us to his image, And as can be proved, we like to put rings almost everywhere, so it is no wonder he but some rings around some planets too. Big scale stuff, of course, obviously.
Still there are funny guys like this one, without a clue about reality.
