How to rebut denials of the existence of photons?



Recently I have encountered several engineers who do not “believe in” photons. They believe experiments such as the photoelectric effect can be explained with classical EM fields + quantized energy levels in atoms. There is a 1995 paper by Lamb along these lines entitled “Anti-photon”.


What are some easily understood experiments that prove the existence of photons, which I can point to in discussions with anti-photon advocates?
