Oh no, you got me. I never knew Science does not accept supernatural explanations. (joke)
Science has always looked at natural explanations instead of supernatural explanations. If a unicorn (or any other supernatural thing) suddenly appeared, then the methods of Science would have to be adjusted. So far that has not happened.
BTW: Science does try to explain supernatural things. It simply explains them in natural ways. Lightning was a supernatural event produced by Zeus. We now have a more natural explanation:
You believe in science except in the areas you cannot accept or that science cannot explain. That is called god of the gaps. The heated debate between Creationism (ID) vs evolution is that the gaps in knowledge of the natural world is getting smaller and smaller.
So the question is: If you accept supernatural explanations for natural events, how do you rule out which supernatural explanation is correct?
