You can't test a nonphysical event with physical testing procedures, Bill. But you can experience it. I couldn't care less whether or not I can prove these things to anybody. I'm not a research scientist or a police detective, and I don't earn a salary for "proving" things.

People just enjoy arguing about this stuff to enhance their own sense of identity, and so they can feel "right". I understand that. Everyone likes to feel right about stuff.
