Burden of Proof
From X, which is the assertion, is not yet disproved. Therefore, X.
This is a Fallacy. X is unproven and remains unproven.
Examples:
(1)Of course God exists. Has anyone ever proven otherwise?
(2)Of course pink elephants inhabit Mars. We don't see them because they blend in. Can you prove otherwise?
(3)Of course Santa Claus exists. No one has ever proved, to my knowledge, that Santa Claus does not exist. And if one were to fly to the North Pole and say: Well, look, there's no toy factory there. A believer could argue: Well, Santa Claus knew you were coming and moved his operations to the South Pole. So you fly down to the South Pole. No Santa Claus factory, toy factory there. So the believer would say: Oh, he moved it back up to the North Pole.
(4) Of course leprechauns exist. Has anyone ever proven otherwise?
(5) Of course ghosts exist. Has anyone ever proven otherwise?
(6) Of course yellow polka dotted aliens exist. Has anyone ever proven otherwise?
(7) Of course X exist. Has anyone ever proven otherwise?
(sounds like mags!)
Proof of a Negative Claim
So you simply cannot prove general claims that are negative claims -- one cannot prove that ghosts do not exist; one cannot prove that leprechauns too do not exist. One simply cannot prove a negative and general claim.
"Negative statements often make claims that are hard to prove because they make predictions about things we are in practice unable to observe in a finite time. For instance, "there are no big green Martians" means "there are no big green Martians in this or any universe," and unlike your bathtub, it is not possible to look in every corner of every universe, thus we cannot completely test this proposition--we can just look around within the limits of our ability and our desire to expend time and resources on looking, and prove that, where we have looked so far, and within the limits of our knowing anything at all, there are no big green Martians. In such a case we have proved a negative, just not the negative of the sweeping proposition in question."-Richard Carrier, "Proving a Negative "(1999) by Richard Carrier at http://www.infidels.org/library/modern/richard_carrier/theory.html
