“”There is no God” is a knowledge claim. Therefore, as such, it demands premises. Simply asserting that you cannot “prove something that doesn’t exist” is fallacious since you can prove you are not in another city currently.”
The burden of proof is always on the person making an assertion or proposition. Shifting the burden of proof, a special case of argumentum ad ignorantium, is the fallacy of putting the burden of proof on the person who denies or questions the assertion being made. The source of the fallacy is the assumption that something is true unless proven otherwise.
Since there is no proof that God exists, there is no sense in believing in God. It is unreasonable to act as if there were a God, or as if the supernatural were even a possibility.
The burden of proof is on those who assert, “There is a God.” There is no burden of proof on those who say, “Really? I don’t see it.”
Notice how it is that if you are in Atlanta right now, you can prove you are not in Philadelphia.
It is illegitimate to claim that you are not in Philadelphia, or Atlanta, or anywhere else because you do not exist anywhere in nature, because you are miraculously supernatural and not of this world.
If you believe that God exists, but not in the real world, then the burden is on you to prove how He could be unreal and yet still miraculously exist (somehow). And you cannot do that.
The atheist need only point out that if this God you believe in has to be supernatural, then He cannot possibly exist (because the notion of “supernatural” is a contradiction of existence).
Atheists do not need to prove that God is not in Philadelphia, nor Atlanta, nor Denver, nor Paris, nor on the Moon, nor anywhere else ad infinitum. All atheists need to point out is that a God Who is Not-Of-This-World really cannot be anywhere.
