As a physicist I can tell you that the answer to your question is 42. Now what was the question again
More seriously, I think Slawomir captured our current state of knowledge with this sentence:

Maybe terms such as wave and particle are just illusory concepts that do not penetrate into the essence of the reality and are just simplistic ideas manufactured by our limited brains

Maybe not "limited brains" but limited knowledge... or maybe both... Basically we don't really know what a photon is. The question becomes not what they are but how we observe them. Depending on the experiment, they can show wave-like and particle-like properties but are neither of the two.
But, wave or particle, photons sure look pretty when coming from the night sky
