It is not necessary to know all these details just to know that such a thing as soul/spirit exists. Do scientists know all these details about Dark Matter or Dark Energy?
As you say...it is very unlikely to convince those who are skeptical. It is a mindset problem.
No one said that it is necessary to know
all these details, but you do need some evidence to go on, or else the idea of a soul/spirit simply remains a conjecture.
Torri has responded to your idea that dark matter and dark energy are similar to the idea of a soul in this respect. I agree with him. The difference is that both the above have indirect evidence, and the words dark matter and dark energy are simply place holders until we know more, whereas the idea of a soul(even used as place holder) is mere conjecture without any evidence to show that it exists at all.
I don't intend getting into the subject of NDEs and OBEs, as we have discussed this subject in detail before.
However I do agree with your last sentence. Indeed it does seem to be a mindset problem. I take the view, expressed in a book I have read recently(Reality Is Not What It Seems):
It is the awareness of our ignorance that gives science its reliability.
And it is reliability that we need, not certainty. We don't have absolute certainty, and we never will have it - unless we accept blind belief. The most credible answers are the ones given by science, because science is the search for the most credible answers available, not for answers pretending to be certainty.
