I think the answer is there will never be 'proof', only evidence. Right now the overwhelming scientific evidence is that all (or almost all) life today is descended from a common ancestor. In short we all evolved. There is no science, be it anthropology, geology, biology, etc., that is in conflict with that. Darwin's mechanism for that evolution, natural selection, is a plausible theory but the truth is likely to be more complicated. Newton was right about gravity but Einstein showed it was more complex than Newton theorized.
Bottom line is that EVERY one of the trillions of fossils found supports the theory of evolution. No other theory comes close. You can attack Darwin but you need an alternative theory to be taken seriously.
