This is a good explanation. Fields are really the fundamental object in QED (quantum electrodynamics) and QCD (quantum chromodynamics), the best theories we have for the electromagnetic and strong forces respectively. In fact, that entire branch of physics is usually called QFT (quantum field theory) to reflect that.
