The problem is that by that logic, every unfalsifiable theory should be treated equally. That means that literally an infinite amount of other unfalsifiable explainations may be the real cause of somthing supernatural. In other words, this means that the chances of any of those are actually real are zero (or at least, a zero with an infinite amount of zeroes before an eventual theoretical 1).

Add that all to the fact that there's a lot of proof on the opposite side of the argument (take for example the fact we know that our brain is who we are, and that there thus can exist no such thing as what people think of as ghosts)...
So while I agree that it can't be disproven, I don't think that should ever be used as an argument, and it is in fact a highly frowned upon fallacy when used in more serious discussions. Of course, this is just a random thread on a Pokémon forum, so it's not really important or anything (and don't think I'm sitting here with foaming mouth typing this), but still wanted to point it out.
