Hmm. You have evidence for this statement, of course? :-)

That is the hand-waving explanation. Yes, it is what many or most
people think is the case, but until and unless someone produces a
coherent theory merging relativity and quantum mechanics, it is no
more than a smart guess. Your objection to the concept of "observing
the photon first" is quite right, of course.
