One cannot give "proof" for anything. One can present evidence that one's theory is the best one going to explain certain phenomena -- and that's precisely what evolution does. No one yet has presented any evidence that Biblical creation is a better theory; all they can do is harp on a theory for which they have only a passing aquaintance. If, for example, you could show how creationism is better than evolution at explaining the fossil record and the diversity of life around us, then you would have a dog in this hunt. However, you can't so you don't. Rale against progress all you want -- science is pretty much going to just ignore you and go about its business.
So then evolution must be charlatanism since as you say no proof may be given.
However, science has been giving proof for thousands of years and advancing man's knowledge and way of living. Seems that to evos an ear bone is proof of evolution, proof that God does not exist, but the entire world around them, its scientific achievements, and even the way in which they communicate their nonsense to others, does not prove anything at all.
