Faith that our lives aren't pointless. If there's nothing after death, then we are little more than bipedal invasive creatures that destroy everything we touch.

I really don't understand that line of thinking. Why does something have to be eternal for it to have meaning? Meaning exists in the moments, in the experiences of everyday life. We create our own purposes, and personally I find that pretty awesome!

: Moral compass. If there's no point to life other than random spontaneous creation of life due to hydrocarbon stacking in an unique fashion, followed by eons of evolution, than why punish murders/rapists/thieves? They are following their genetic predisposition, after all, and in the end (the "big picture"), there's no repercussions if we live only to cease living.

Morality is a result of our socialization and evolution! Even robots develop altruism!
