BOT...........
I'll say first that I am catholic (how 'true' is TBD), but the afterlife question really bugged me, I'll always been a simple, basics, facts sort of guy. The heaven thing get me because, A.)How big is heaven really? Can it really "fit" all of us in there for ever and ever? B.) If we are indeed waiting for judgement day, what will we look like in heaven? I would have a great fear about what freakshow we'd look like with our decomposing bodies. Or if we got to pick what we looked like, be it sometime earlier in our lives or something completely different, how would we know what are family and friends look like? I've seen pictures of my parents when they were younger, but I doubt I could pick them out of a lineup.
When I was younger, I had a completely weird train of thought, I was sort of mix of both Christianity and Buddistism, you were reincarinated till you were human, I was never sure how many times or what have you, but once you were human, and 'were able to get into heaven.' Bad people were sent back to 'start over again.' Sort of a earth's is heck, type thing.
Now, I dunno, I honestly really am unsure that there's anything after the last electrical pulse your brain shoots out. That doesn't mean life ain't worth living, but you always should make the most of what you got.
