Mister Silver
Faith's Nightmare
My position is that non-physical entities can affect the physical and that can be detected. But that is not predictable so it can't be studied by the scientific method.
Also, there are psychic senses we possess that can perceive what physical senses and instruments can not.
I like watching Ghost Hunters, too, doesn't mean I accept it as more than a fictionally based reality show that caters to people who believe in ghosts even the show itself has provided no real evidence of ghosts.
