Proof is simple, I don't need pictures or video, those aren't trustworthy. I need measurements taken by accredited instruments that are linked unequivocally with paranormal activity. No such instrument exists. In order for ghosts to be real, and for stories to be true, there must be some energy clustered, and thus readings should be possible. If not then there is no possible way for ghosts to be seen or interact with the environment as suggested by the stories. And there cannot be any other possible explanation for it. And considering that the RELIABLE detection instruments found nothing in supposedly "haunted" areas, I cannot believe ghosts to be true. Ghosts interact and are present in some way in the physical world. They can't move something without being present, that presence should be able to be detected by science. Since it isn't all of that is BS. Science has explained why ghosts don't exist. Really, find me some concrete evidence that isn't from hokey science that can hold up to scrutiny, and I'll be a believer. While we are at it, we'll gain some money.
All believers in ghosts agree on one thing, that ghosts exist as a manifestation of the human spirit (energy) in the living world that can interact and be seen. Go back to that hotel alone and see if you can replicate that spirit, she must still be there, right? Prove me wrong. I have proven to you why I believe to be right using links, scientific evidence, and you have given me anecdotal evidence that could have easily been fabricated to cover something else up, or could have been changed or exaggerated. All it takes a little fear to make people believe, and if there is a naturally occurring frequency of about 18Hz (just below the human detection limit) and the mere inclination that a ghost MIGHT exist to make someone up and leave. Frequency of Fear
Again, if ghosts were real, or any other paranormal then Mr Randi would have been out a million dollars LONG ago. His standards were agreed upon by BOTH sides. In other words, every single person who took part in that challenge believed that they could prove the existence of paranormal phenomena under laboratory conditions. NOT ONE COULD IN 30+ YEARS! NONE! Hell, none even passed the preliminary phase.
