This is a silly game. There are different kinds and standards of proof. Mathematical theorems are proven by following defined rules of inference from given axioms. Legal proof is by 'preponderance of the evidence' or 'beyond a reasonable doubt'. Science doesn't even to pretend to 'prove' things, although it can prove some theories are false in the 'beyond reasonable doubt' sense.

Three things that one cannot prove or disprove

1. That God exists or does not exist.

Depends on what you mean by "God". The omniscient, omnipotent, omnibenevolent God of Christianity does not exist because his definition is incoherent and also the evidence is against him beyond a reasonable doubt. But if he not omnibenevolent, like the Deist god, those disproofs don't apply

2. That I exist or do not exist.

If you didn't exist you couldn't ask for a proof.

3. That computers can be conscious or not.

Just like other scientific questions it is beyond a reasonable doubt that most computers are not, but if computers exhibit suffciently intelligent behavior their consciousness will be established beyond a reasonable doubt.


It's possible to prove that computers can be conscious if it can be
proved that the physical movement of the parts of the brain can be
simulated by a computer.
