And while we're on the subject of "what happens when you die", the answer is nobody on the face of the Earth, past or present, ever definitively had an answer to that. Many people believe they know, or have an intuition enough to commit to a belief that they know, but no one -really- knows.
Once this question comes up it seems to lead us to all sorts of other arguments of religion, philosophy, science, ethics, and similar. It really is difficult to consider "what happens when you die" without establishing your position within that larger framework. The problem is, of course, that large framework is tar baby (that is, you start arguing one thing and end up arguing another, and another, and end up exitricably bound up in a quagmire of exceedingly difficult epistemological positions), and usually is unpleasant.
I know when my family gets together it seems we never talk about religion or politics because it leads so easily to a shitty ttime. I may be the exception though because I enjoy it and would like to see more religious and political arguments at family gatherings. It's so much more interesting than the regular banter and small talk.
Anyway, my personal position on this question (a position that it seems to me is the -only- reasonable one) is agnostic. We simply don't know about if anything we can call God exists or if there is life after death. I should note that while I would have to label my beliefs here as agnostic, I tend toward atheistic-agnosticism. My leaning toward Atheism in this regard is my own personal intution and reason and my background. Thanks for reading.
