I object to the term "supernatural". It means more like "supermaterial" or "super-harnessable-in-an-experiment-by-humans". It has well known limitations. Regarding speculation, that assumes there isn't steps to knowledge about other things which physicists do not take. Any scientist will easily change their mind with the right evidence. The only issue is that the evidence takes place in one's subjective experience. It may take place specifically in contexts where it cannot be convincingly demonstrated to the general population. It sounds silly, but if that's the nature of the object of investigation, it's necessary.
