When someone tells you that Santa Claus is real, can you prove him wrong?
No. And I’m gonna make this short.
You can stay up all night on Christmas Eve, wait for Santa to come down the chimney, and he won’t show up. BUT, that won’t prove that Santa isn’t real, in fact, it indicates that he didn’t show up that night, or decided not to show up because he knew you were waiting for him.
If someone had told you that they can move things with their minds without touching them, how can you prove them wrong? What you can do is ask them to prove themselves right. And if they can’t, it makes them wrong.
In conclusion, when someone comes to you with a hypothesis about the existence of something, they should be the one to provide proof for it.
