It's possible the Earth did have a ring for a short while around 4 billion years ago, when it was hit by another planet around the size of Mars, (the impact threw matter into orbit) But the ring was unstable, so coalesced into what we now call The Moon. Thats an interesting question. To be honest thats a bit above my pay grade to do that calculation (andit looks like long-term stability would really be an issue), but lets assume that small pebbles and such could last long enough to give Earth a ring system.
