We atheists hold a funny POV, because if/when we're "proven" correct, we won't be around to go "Ha! You see?!" to all the rest.
Properly processed, though, this should make us realize that we won't get the last word in most situations. I'll have my truth, you'll have yours, and we'll either live together as best we can with our convictions... or rush each other even faster to dust.
Proving that we were "right" isn't how we live well.
It's how we show up for each other in the fray that counts.
@MLClark it depends on one's definition of Atheist. Your post implies the "there isn't a god" position. An alternative that is present based is "there is no evidence to support the existence of god".
Agnosticism is the measure of one's capacity to "know" whether there is or isn't, so one can be an agnostic atheist, no problem, but the "proof" would still come at the same juncture, post-mortem.
The better challenge to what I wrote is to point out that one might believe in an afterlife absent the existence of a god - which is possible. The shorthand of a single post doesn't allow for those more Buddhist-atheist interpretations of a continuity of consciousness, but they exist.
May your delight in us mortal fools continue apace for many millennia to come. :)
