That is only good for the person that accepts the testimony. That does not demonstrate "ghosts" to others. All one has to do is consider one person's reliable testimony as more stories and the debate continues on without resolution.@George-ananda
If I understood @George-ananda: , he not claiming to “know” definitely that Ghost exist. (he is not claimng to be 100% certain) , He is simply saying that he believes in ghosts because he knows of testimonies that he considers reliable.,
You trust in reliable testimonies all the time to gather knowledge, so why making an arbitrary exception with Ghost.
I personally don’t believe in ghosts ether, but reliable testimonies would convince me , it would be intellectually dishonest to accept testimonies for things that I like and reject testimonies for ideas that contradict my view.
You do not even understand that for your scenarios to hold any water, much would already have had to be established about ghosts that has not been established.
Anyone can make up fictional scenarios that prove their point even though they do not.
