Of course.
The existence of light is a verification of the ether theory of light.
No it isn't. Your examples may be considered evidence but not proof. Why is the concept of falsification so hard for you to understand?
you make the baffling remark that the double-slit experiment "verifies that photons are waves." It seems that you do not make clear distinctions between presuppositions and conclusions.
Photons are waves. Particles are waves too. Everything is a wave/particle. I don't see what your problem is.
All of this is probably part of a larger framework which includes philosphical marvels like 'you can't prove a negative', 'things cannot be proven, just falsified', 'the burden of proof is always on the other guy', Popperism, 'everything is made of nothing', 'scientists don't try to prove a theory' and so on. The ultimate purpose of these nonsensical beliefs probably have something to do with being an intellectually fulfilled atheist.
All of my statements are true. lets take an easy one for you. I claim that you can't prove a theory, you obviously claim that you can. Prove me wrong, prove that God exists. I will wait but I won't hold my breath.
