The difference between magic and science is that science exists.

Obvious answers aside. OP, you seem to operate under a misunderstanding of what science really is. Science, or natural philosophy as it was known before, is a relatively recent thing. Knowledge is not science. Skills, even those related to what we consider "scientific" fields like medicine or architecture, are not science either. Science is a specific process which we use to come to conclusions that broaden our knowledge and make sure that this happens in a way that is logical and consistent with our understanding of reality, as opposed to "this is true because it just is/because I say so".
