There's a couple of reasons behind my thinking.
One is that the rings would likely as not be formed by the matter that'd otherwise have formed the moon.
The second is that, if there were rings and a moon, the rings probably wouldn't last, as the moon's gravity would destroy them. This would either be because the contents of the ring would be knocked out of orbit, either towards Earth or into space; or because the moon would accrete the material to itself.

Universe Sandbox, a nifty simulation
...says that if earth had rings like Saturn, they would be unstable with the moon.
This screen is from after only 21 years of the rings magically appearing.
The strange pattern is because the moon does not orbit the equator.
However, even if we did have a moon that went round the equator, the
rings would still break apart.

200 Years since the rings appeared and things are surprising stable
Camera moving, not the rings.

One Ring to rule them all, One Ring to find them,
One Ring to bring them all and in the darkness bind them
