My point is this. You have never experienced the bone-chilling winds of Mount Everest but you take witnesses' accounts at face value. Why are ghosts different? Hundreds of wittnesses, some even notable people in history, have claimed to see ghosts. Why do they not get the same benefit of the doubt? Why do you completely discount something simply because you have not experienced it yourself? To me, that places oneself on a very high pedestal. It implies that you are perhaps the only one qualified to make such a call for the rest of us. Until you see it, it hasn't happened. Did the crashing of ocean waves not occur until you witnessed it?
Yes, my language is intentionally "trollish". But that is simply to emphasize a point. I don't mean everything I wrote in the most literal sense.
(These days, with everyone being so sensitive, one can no longer assume such understandings.)
Even if we wanted to entertain the possibility of ghosts existing, we come up against the multiple offers and invitations made over at least 120 years for anyone to provide evidence if their existence. Every proof offered has been thoroughly debunked and no one has ever supplied a shred of evidence to support their existence.
The belief in them is easily explained by our desire that the spirits of the dead continue to exist in another form.
Fairies, trolls, sprites, gods, men of the forest, demons, ad infinitum reappear in almost every culture in various forms at various times, but their tendency to take the expected forms of the day, and the powers and knowledge assigned to them speaks much more of them fulfilling a psychological need or answering questions about who we are and where we came from than actually representing an existing reality.
