The disputed existence of ghosts/fairies/God/moving virgins is not a matter of opinion. It's a matter of producing evidence by the people who make these claims. If you make a claim that counter-intuitively contradicts all known laws of nature, then it's up to you to try to verify your claim with evidence. Proper evidence if you don't mind. It is not up to the rest of us to "prove" you wrong. The ball is entirely in your court. The existence or otherwise of God can't be a matter of opinion. It's far too important for that. So let's be seeing your evidence.
