Poll a random group of one hundred people and you'll probably find at least thirty who believe in ghosts/spirits. A further ten of those people will likely believe in hauntings. I do not count myself a member of this group of people. There are just too many problems with the idea for me to subscribe to it (aside from the obvious lack of evidence). For one thing, this planet has been home to roughly a thousand trillion deaths over billions of years. Yes, billions, not six thousand. Sorry, Jesus freaks. Yet there seem to be maybe a hundred and twenty seven ghosts in existence and for some reason most of them lived in the Victorian era. Where are the Neanderthal ghosts? The Viking ghosts? Or more importantly, the dinosaur ghosts? I mean, what, only humans come back as ghosts? Humans from the Victorian era? If ghosts were real they would be everywhere.
Not only would they be everywhere, if they had the ability to haunt life would be absolutely fucking unbearable because everything would be haunted.
Get it together people. You can rest easy tonight, okay? There are no ghost pterodactyls flying around your bed.
