The first thing i think when i see that question is no, i feel like there would be more hard evidence in the world if supernatural beings exist. I think the mind hears stories and tales and when something unexpected happens it finds something to fit to a extent. The idea of supernatural beings has been around for a long time and maybe there would be more solid evidence, more time and energy put in to researching it than fringe groups who never seem to find too much proof and people seeming to just make money off the whole thing by playin to peoples fears.
just some ramblings heh, im a bit tired and these are just my first thoughts, i havnt really thought about it properly so ill ponder some more and see if i can come up wit a better reply
im willing to be convinced if anyone has some good info on the whole idea
