I kind of disagree with you there. The atheist perspective on the human body is that we are, in some sense, extremely complicated and beautiful machines.<quoted text>
Atheism my friend has never stopped anyone from dying and it never will.
Yes, organic. Yes, ridiculously complex - to degrees that no human could ever fully grasp, but that's what supercomputers are for.
Anyways, if you get the tinkering just right, you could create renewable youth - and that would basically be the same as living forever. Provided you continuously had access to the tech.
Even then, nothing lives forever. Even if we had that tech, we'd die in unpredictable disasters or murder or other situations.
