I guess it really all depends on your philosophy of science. Is the idea of naturalism inherent in your understanding of science? If so, then anything supernatural doesn't fit into the category. But the presupposition that everything MUST have a natural cause is exactly that, a presupposition - it's a worldview, a philosophy. Science is just all about making observations of the world around you, interpreting those observations, and then drawing conclusions to explain the observations (experiment and repeat). Our worldview enters the process in the interpretation stage. You always process and interpret your observations through the lens of your base presuppositions. That's just the way the world works. If your presupposition is that everything has a natural cause, you will exclude all explanations that are outside of that box. If, however, you're open to the idea of the supernatural, that also shapes the conclusions you reach. Now I'm not suggesting that we revert to the ignorance of "We don't understand it... God must have done it" or "It's magic, we don't have to explain it." But the early scientists set out to understand the world because they believed in God, which gave them confidence that the world would be orderly and not random. Belief in the supernatural doesn't have to lead to ignorance. But I digress. I don't believe in magical powers any more than I believe that being bitten by a radioactive spider would give you spider powers. My point is, I don't get the mindset that science only has to do with natural causes. I think that's an unfortunate mindset to have in real life, but it's ludicrous to hold on to in a fictional universe that is the home to advanced alien civilizations from different dimensions, mutants, and super soldiers who survived being frozen in ice for 70 years.
