It's not just American, you're dealing with a worldwide conspiracy here.
I don't anticipate you proving anything to them either, not because of conspiracy, but because of lack of merit.
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?
