I think that ‘it’ is a lot more crazy than true.

I don’t believe in spirits and I don’t believe in an afterlife. We come from nothingness and return to nothingness. We contribute, in a very small way, to the evolution of our species. In the blink of a Universal eye we will adapt, we’ll be replaced by our future species and ice ages will return so we’ll bundle up, eat blubber and take up crochet.

Interesting question. Mainline Christianity is largely silent about what goes on in ‘heaven’ (afterlife), right? Islam gives a few hints but I don’t think that most Jewish folks believe in an afterlife, either. No heaven, ya know?
