You constantly repeat the mantra that the theory of evolution is valid while at the same time you deny that any proof of it is possible. If there is no proof then how can it be a valid theory? If there is no proof, how can it be called science. If there is no proof how is it different from an atheistic/materialistic belief?
There is no proof, there's evidence, despite your claims to the contrary. That's what is required for a theory. Take advanced math if you want to get into proofs.
