Hi, and welcome to the site and forum. When I first found this site i was having the same kind of feelings as you, it used to scare the living hell out of me, and it wasn't dying itself that did it, it was the idea of non-existance afterwards. After readings Bruce's books and other books on the subject I have started to discover my confidence and belief in an afterlife and that non-existance is nowhere near as scary or real a prospect as it used to be.

As to how the idea of an afterlife fits in with evolution, its funny as humans we are sometimes to intelligent for our own good, we like things to fit together like a jigsaw puzzle all in their place and all a perfect fit. Life however is rarely like that as we all come to learn. The idea of an afterlife, as I see it, isnt that human people go there and come back here but rather that our spirit comes back and forwards, therfore it wouldn't matter if we had never evolved or if we had evolved into giant orange headed turtle people we'd still be going and coming between here and the afterlife.
