The way science works is that it proves its propositions. There is absolutely no proof for the theory of evolution but there is tons of proof for all other scientific theories. Half of what Darwin said in his books, on what he based his theory has been disproven by real science. The evolutionists never enter into discussion as to what the science is of their atheistic/materialistic philosophy because there is none.
Yet he also admitted his ignorance and predicted that according to his model, many things must be found. And guess, what, they were, long after his death. That's evidence.
