As others have said, it sure would be nice if our minds and spirits continued in some way. I'd like
to believe in that, just as I'd like
to believe that ETs have visited us and continue to do so. I'm not kidding, I'm a dedicated SF fan, trekkie, etc, and if aliens landed in front of the UN building tomorrow, I'd be dancing in the streets (unless they started shooting
But I can't
make myself believe in aliens because there's no evidence for it. Lots of anecdotal evidence, lots of people willing to berate me for not believing, but that's it. I consider myself lucky in that I'm the type of person who cannot be browbeaten into accepting something, but I can
change my mind if the facts go that way.
As with ET, if god did appear tomorrow to tell us we exist forever, I'd be pretty happy -- although if it was the christian/hebrew version I'd have some hard questions for him. The xian god as depicted in the bible is not an admirable being. If you accept biblical accounts as true then he is a psychopathic, vile, sadistic little shit of a troll. And the universe is too orderly, too predictable to have been created by such a low-life asshat. Therefore IMO at minimum
the bible has to be wrong about its depiction of god. Once you accept that, the question is not "is the bible wrong" but "how wrong is it". It's a steady logical slide from there to the question "do we even have any evidence at all of the existance of god" and the answer is no.
I'm still prepared to be convinced. But having grown up in the xian milieu, I know all the arguments, both catholic and protestant, and they really come down to variations on browbeating, playing on people's fears, and emotional appeals.
