Reddit reviews Glimpsing Heaven: The Stories and Science of Life After Death

> if I needed to, I could go to a school and learn all about such things and do experiments

But of course, you will not do that. You'd see it as a waste of time. There are people who claim that they've done so. And you trust them. Because your heuristics about people say so, not because you verified the science.

> use that in experiments and make reliable predictions. I do wish such things were testable and verifiable.

Try these:

Glimpsing Heaven

Extraordinary Knowing

These aren't proof in their own right, but they should give you ideas of what you could test if you wanted. Extraordinary Knowing could point you to research that has been done, is rigorous, and does favor the existence of psychic phenomena (though not about spirit life in particular).

You could take steps to try and test and verify this for yourself. One easy way might be to go to a good hypnotist and do several regressions. If the regressions are clear enough, details might come to you that you have no way of knowing, and which you can subsequently verify. Not proof of reincarnation, but subjectively strong evidence.

There are ways to test and verify, and it doesn't take much to come up with ideas how to do so. It's not even nearly as hard as measuring the electron, or finding the Higgs boson. We just don't want to.
