Subject: Is gravity a particle, field, or distortion in space-time?

I've read about the graviton, a particle the nucleus emits which 
carries the gravitational force and that's how I generally think 
of gravity.  I also see a lot of the answers on the website refer 
to "gravitational fields" and "distortions in space-time".  Which 
is the best way to describe it?  Can it be considered all of them 
like the way light can behave like a wave or particle?  It's 
harder to accept that paradox for gravity than for light because 
either the graviton exists or it doesn't, and if gravity is 
explained as a distortion in space-time, then that means that 
there exists no particle which carries the force.
