... All cultures that I know have some sort of afterlife. Greek paganism had the underworld, Christians had heaven, hell, and purgatory. As being part of a culture, I believe in it's afterlife... That's all I've got to say.
so if i believe in Greek paganism i might go to Elysium,while if i believe in Christianity il go to paradise?and if i don't believe in nothing when i die il hear a voice saying "you imbecile!you will go to infinite darkness for not believing!you didn't go to church!you questioned god! darkness to you! "
so in ancient times,and that means before 2010 years,you would go nowhere just because you did not know god.
edit:do i need to tell you to see zeitgeist movie?
i think i do

That's what happens. Sensory input ends, brain is destroyed, and perception and experience ceases to exist. "You" disappear.
Anything else requires some very wild assumptions.
