you can't prove there is a spirit
isn't that just a belief?
man needs to believe in a life after-..and/or a spirit......if not, humans will feel ''empty''
do you believe a spirit lives after the body is dead?
does the spirit have the ability to ''see/feel/hear/etc?
I don't feel a spirit
my brother is very religious..he said he felt something/a spirit/god at one of those singing/praising/group things
1. isn't that just what he wants to believe---people believe a lot of stuff that is not real--especially if they are deeply immersed in the subject? such as UFO believers
2. what did he really feel?? didn't he really feel normal, human emotions?
there has never been a true miracle/sighting of god/sighting of a spirit/ etc
Do you wish to talk science? Proof and evidence require material things. Religion is not science, it is philosophy.
As for body, mind, and spirit: The body is physical, and in many respects so is the mind. It gathers data. There are some who believe the mind gathers data and argues with itself until a determination is made. Others believe it is more (and less) complicated than that. That the mind collects data, but it is spirit that makes the decisions.
The argument that man "needs to believe in an afterlife" is a conclusion atheists have formed for people who do believe. They compare us to those who believe in UFO's, flat earth, no moon landing. We just laugh.
Yes, there have been true sightings. However, that cannot qualify as science, because science requires that the experience must be duplicated. Juan Diego, Bernadette, the three children of Fatima are dismissed because their experiences cannot be duplicated.
For me, it is not a matter of "believing" the spirit (the essential person) lives on after death, I know it lives on. (I know this makes me a "crackpot"

, but it is what I know and I cannot deny it.) I think this is probably the same thing your brother lives with. He cannot deny what he knows to be true. Since there is no "evidence" he lives in a lonely place sometimes.
