yeah i know. speaking of evidence, do sound recordings count?
It would be evidence, the question is, would it be
credible evidence.
Let's pretend I decided I wanted to fool people with my fake 'ghost' recordings.
So I get recording equipment and then do a voice over which I claim is a 'ghost'. People decide to spend time and resources testing my 'claim'. So the tape is analyzed, and the voice is found to be just a normal human voice.
Well OF COURSE it is, (I say) because it's the ghost's voice and she was a normal human. Why wouldn't her voice sound that way.
Anyway, it's easy to get to the point where you can't disprove it because you cannot know the conditions under which it was made. But it doesn't make it credible evidence when there's another more reasonable explaination.
So...let's say I decide fine, the main objection is no one knows how it was made. So I get some people over, people who are respected and are just normal people. Then I hide sound equipment to project the 'ghost voice' into the room. Same recording, same sound. Aha! I exclaim, my tape is PROOF now.
Well no, it's not (plus its fake

). Again, unless someone is present and finds the other equipment they can't 100% disprove it. Yet, once again we can say that someone planting sound equipment and making a fake is a more reasonable explaination for the normal human voice on tape, than 'ghost'.
And so it goes. And it seems to me that people who just
want to believe (or perhaps need to, I don't know) cling to the shreds that are 'you cannot 100% disprove it unless you clearly uncover the fakery'. Yet even if I made such a tape, and conned people into truly believing in it, and THEN showed how it was done, you'd have some people probably still believing in it anyway, and most of the rest who previously believed would just say 'Okay that one was a fake, but what about THIS authentic tape over here...' :\
