The problem with this is, it is impossible to disprove that something exists. the burden of proof always lies with someone making extraordinary claims. I became aware of this when I did a lot of reading and thinking about the existence of God, but it equally applies to the paranormal or supernatural. Bertrand Russell came up with a good analogy for it, known as "Russell's Teapot". From the Wikipedia article - "Russell's teapot, sometimes called the Celestial teapot, Cosmic teapot or Bertrand's teapot, is an analogy first coined by the philosopher Bertrand Russell (18721970), to illustrate the idea that the philosophic burden of proof lies upon a person making scientifically unfalsifiable claims rather than shifting the burden of proof to others In an article titled "Is There a God?" commissioned, but never published, by Illustrated magazine in 1952, Russell wrote: If I were to suggest that between the Earth and Mars there is a china teapot revolving about the sun in an elliptical orbit, nobody would be able to disprove my assertion provided I were careful to add that the teapot is too small to be revealed even by our most powerful telescopes. But if I were to go on to say that, since my assertion cannot be disproved, it is an intolerable presumption on the part of human reason to doubt it, I should rightly be thought to be talking nonsense. If, however, the existence of such a teapot were affirmed in ancient books, taught as the sacred truth every Sunday, and instilled into the minds of children at school, hesitation to believe in its existence would become a mark of eccentricity and entitle the doubter to the attentions of the psychiatrist in an enlightened age or of the Inquisitor in an earlier time." Like I say, the analogy was specifically about the existence of a God, but it applies to any fantastical claim.
