It is perfectly possible to prove a negative. I claim there is not a bottle of soda on my desk. I have looked at my desk, felt around it, brought people in to confirm it and have demonstrated objectively there is not a bottle of soda there. Very easy.
In order for that to be a negative someone would first have to claim that there is a bottle of soda on your desk and it would be up to them to provide the evidence. Since we are clearly talking about supernatural phenomenoms James Randle said it best with this "When James Randle coined the phrase "you can't prove a negative". He claims that he cannot prove a negative (such that telepathy does not exist), but he also argues that an individual who claims telepathy exists must prove so. He discusses that induction is often used as a mode of proving a thesis, but if an individual assumes that something is or is not, then the person must prove so. Further, as he says, he does not take an advocacy position, as a lawyer would. He says that he cannot prove that a negative is true, but he could attempt to use evidence and induction to support a claim that he is biased toward, such as a claim that something does not exist (ex. flying reindeer)" A better example of this is Russell's Teapot
Russell's teapot, sometimes called the
celestial teapot or
cosmic teapot, is an
analogy first coined by the philosopher
Bertrand Russell (1872–1970) to illustrate that the
philosophic burden of proof lies upon a person making scientifically
unfalsifiable claims rather than shifting the burden of proof to others, specifically in the case of religion. Russell wrote that if he claims that a
teapot orbits the Sun somewhere in space between the Earth and Mars, it is nonsensical for him to expect others to believe him on the grounds that they cannot prove him wrong. Russell's teapot is still referred to in discussions concerning the
existence of God.
No. I need only claim it is not there. That is a negative claim and I can easily prove it. The person making the claim, whether it is negative or positive, has the burden of supporting the claim. You can't make a claim, declare it to be negative, and then act as of that claim is proven based upon your in ability to prove it. If you can't prove a negative claim, don't make a negative claim.
Do not confuse belief with lack of belief.
I'm not. That is the point. A lack of belief in the total absence of evidence is neutrality. You are not neutral. Therefore, you do not lack belief.
