Chiming in to agree with BA.
The moon (or any satellite large enough to cause significant tides) would decimate the rings. Some scientists argue that without a moon, life wouldn't have gotten started nearly as soon as it did (if at all).

Also of note:
The gaps in the rings are caused by shepherd moons, that clear out pathways between the bands.
The rings would have appeared more blue/green due to reflected light from the earth.

But the pictures where pretty :)
