In addition to my earlier post:
Have you ever seen a ghost?
No.
Have you ever researched or looked into ghosts in the town you live in?
No, not in my hometown, but I like a good spook story.
Have you ever been on a ghost hunt?
No, but that sounds quite fun as well.
Or do you think its all silly nonsense?
Yes.
It is generally regarded to be impossible to disprove the existence of something, or prove the
non-existence of something. (Can you prove I
don't keep an invisible dragon in my garage?) So if there are "unexplained phenomenon", my first reaction would never, ever, ever be to assume it's ghosts, spirits, gods, or aliens. The most rational position, in my opinion, is to say, "I don't know," and wait for evidence that supports a possible explanation. If there is no evidence that supports one position, it is very unreasonable to think that this makes the other more true or more likely.
Here's a phenomenon I find to be quite similar: Crop circles. Some decades ago, a few guys pulled a practical joke by making these shapes in corn fields (I think that was in Britain, but I'd have to look it up). They got better and better, their shapes became more and more complex, and other people started doing it. It was taken seriously by a lot of people and some claimed the shapes were too complex to be of human origin. (Think about it: We have space ships that fly to Pluto, but using a string and a lawn mower or whatever is too difficult.) After a while, the guys admitted they made it up and explained how they made the complicated shapes. And what happened? Nothing. The media ignored them, because the fake stories were more popular and made more money. Copycats kept doing it, nobody listened to them, and there are still people who think aliens are communicating with us.
@Mr. Pole I'm not comparing crop circles to paranormal phenomenon as ghost or similar things. I'm comparing the mindsets of people who believe in these things. If something really weird happens and your first thought after not being able to come up with a natural explanation is "ghosts", that's the same as saying "aliens" if you can't explain how those crop circles got there or what that light in the sky was.
