I was asked for references. I would suggest as a starting point
Richard P. Feynman's lecture of April 3, 1962, which was an
introduction to quantum behavior. I think the whole of the lecture is
worthwhile, but especially the following paragraph:

In Feynman's introductory lecture number 1, he
says: "I want to emphasize that light comes in
this form - *particles*." Also: "... light is
made of *particles*." emphasis mine

Feynman's lecture number 2 is titled
"Photons" *Particles* of Light" He says:
"Quantum electrodynamics 'resolves' this wave-
particle duality by saying that light is made
of *particles*, ..." emphasis mine

If I understand it correctly, a cornerstone
concept of QED is that nothing exists except
particles.
