No one can see atoms. Amazingly, science still proceeds onward. Your rhetoric is also one sided in that you demand more proof than you are willing to offer yourself. You demand visible proof for knowledge of the creation that comes from studying it directly, yet do not require such positivistic evidence for knowledge of the creation that may come from bibilical interpretation. Darwinism, the interpretation, is metaphysical.
Evolution is still a legitimate scientific concept.
The two are not automatically inclusive. A closer look at the genes of different primates could feasibly rule this out. This is not my experience. This is the positivistic argument again. I go back to the atomic theory model.
