Ok fine /science What’s the best argument for why light is a particle? Note: not why light emission and absorption is quantized, that is different I already believe it

Quite simply, a quantum of light can be measured to have a point position in space, much like a particle but unlike a wave. You can think of it as a localised wave or ‘wavelet’. But put many such quanta together and this no longer becomes possible on account of their interaction.
