"Anything not made from subatomic particles" is a poor definition of the supernatural, since it leaves is irrationally prejudiced against the idea that subatomic particles could be made out of something else, which is a perfectly reasonable hypothesis (currently one with no evidence for it, but we still shouldn't be preju...
