I mean, it doesn't relate.
An unicorn would be super natural, right ? but imagine, in a different realitiy, where it actually exist, no one would bat an eye. that is just a horse with horn.
my point is, you say it is "supernatural", because you judge something not possible in our reality, but to them it isn't supernatural
If you show a movie with some of today tech to the people in Star war , they would consider it "science fiction. supernatural", and the gap of the back then understanding of science is less than one life time
