It's a rdiculous question was my point. Scratch that. I mean oh heavens yes I'd just gather my family and all my believing friends, go to a church and drink poisoned kool-ade on a Sunday and just end it all.

If I might ask the question in a sincere fashion, what would you do if it were sufficiently "proven" to you that there was no God or afterlife? (And didn't believe because of Pascal's wager, etc.) I'm curious about this because it often seems that Christians hold the mortal life in relative apathy (and justifiably so).

And ridiculous or not, this is a philosophy forum, and we should not be strangers to the impossible but interesting "what if" scenarios.
