What exactly is fire?

I've always wondered, what is fire? It's not a solid. It's not liquid. I don't think it's a gas. I don't think it's a bunch of ionized gases or whatever plasma's supposed to be.

In a candle flame, the molecules are whizzing around so fast they smack into each other knocking electrons out of orbit and sometimes off the atoms completely. The orbits are not continuous but are in the form of energy levels, the electron thus snaps from energy level to energy level quick enough to create an electric field, the electric field creates a magnetic field which perpetuate each other, this can be modelled as a photon of light.

Every gas with a temperature releases radiation, however because the chances of an electron shifting collision are so low this radiation is very dim. Heated gases simply speed up the process allowing the radiation emitted to be visible.
