[Avatar: The Last Airbender] Why is it that all of the benders move things that are already there, while the firebenders just shoot fire out of them?

Earth, air, and water are physical things that exist; fire is not. It's energy. Zuko and Iroh talk about this when they're training - firebending has a lot to do with breath and manipulating energy. They create the fire that they bend from themselves, rather than moving something that already exists like the other bending traditions do.
