So, where's the evidence that witchcraft has ever actually done anything? If it really works, it should be pretty easy to do produce an experiment that will totally floor the scientific community and force them to accept the existence of these supernatural powers. Scientists are always willing to be convinced by good evidence, so long as the methodology is sound and the results can be replicated, so let's see it and revolutionize our understanding of the basic forces at work in the universe. Give me an experiment that I can do to prove to myself that this stuff is real.
