Thousands of experiments. Off the top of my head:

Direct evidence:

Single-photon diffraction experiments, single-photon *anything*
experiments.

Indirect evidence: blackbody radiation and the photoelectric
effect, which are inconsistent with un-quantized light. Why
is there a minimum frequency for the photoelectric electrons
to be emitted?

Single photons are routinely detected in experiments all
the time.
