A problem I think may exist with the current theory of how the moon was formed is that if it is correct then it would seem somewhat logical to expect the earth to have a ring similar to the rings that the gas giants have.

That video is actually what made me consider that there may be a flaw with the currently accepted theory of how the moon formed. If something hit the Earth hard enough to shoot up enough debris to clump together into the moon then some of that debris should have also been able to be within the area where they would have form a planetary ring. I don't, I'm not a physicist so I could be completely wrong.
I may delve into the planetary differentiation and describe Earth layers one by one, but the matter boils down to one substantial thing: density of an object. A dense matter exerts a more potent gravitational pull than, for instance, Saturn's planetary ring made of chunks of ice and dust.
Earth's dust and debris were more massive and denser than Saturn's ring, and subsequently coalesced into our natural satellite.
The Roche limit should explain pretty much everything. Density and distance... in essence, gravity.
