@Dabs:
I side with Jay on the afterlife part. I would even say that the odds of it existing are far fewer than 1%. Perhaps 0+% (the + is for being scientific). As for your bet on it existing or not and where it will land you after you die, it's an interesting argument that many people use (i.e., winning this life vs. an eternal afterlife), but, according to almost all religious texts, this mindset will not land you in a nice place after you die, so you'd better pray there's no afterlife...
Its a little bit more involved than that, I guess you could say it starts with that mindset, until you change your way of thinking and willingness to help other people and your fellow brothers in humanity. Whether the answer is yes or no, I would like to live a life where I am remembered by at least a few that I have had it okay or good or something along those lines.
Proof or evidence is a matter of faith. One can not really see it, but either you take the leap or you don't.
The mindset I prefer is one stemming from love, not fear. Criminals fear law enforcement. Good people are good just because they feel good when they do good.
