The Earth may have had a ring formed from leftover debris very early in it's life, possibly even predating the Moon. However, with nothing to keep the ring in place it gradually dissipated.

True the earth did most likely have a ring system early on in the planets formation. Many scientists theorize that another large planitary body, about the size of Mars, struck primordial Earth, rusulting in a ring system that eventualy coalesced to form our moon.

For those who want a new ring system, take heart; it's hypothetically possible that the Moon's orbit will one day destabilize, causing it to fall within the planet's roche limit and be transformed into a planetary ring. In a few billion years, you may get what you want.

Not likely because the moon is moving away from us at a rate of about 3.8 centimeters per year.
