Personally, I am a theist ( btw, sunnah, a theistic person does not believe that everything is God's will, the whole reason we are people and not machines is choice, which comes with the "soul" ). In a world where humankind is like my computerized characters in a game ( albeit with more complex coding ), and now this thought is hard to explain, we would not exist.
Look at the way we see, we don't just detect objects and react, we SEE, the world is laid before us. When you stub your toe, you feel in 3-dimensional coordinates, you don't just... okay, I cannot explain it, and you can explain it away using nerve positions, etc, but consciousness is not just a series of mathematical operations, it requires something non-mathematical, something different, to operate in this way. Here comes theism and souls. ( I am a biologos, words of life, DNA, it's obvious that the universe was started with a "goal" in mind. Next paragraph. )
God doesn't neccisarily have to be a man in the sky, God is a power beyond the universe, unrestricted by our physical bounds. The holy books written by various religions ( excluding Islam, since Muhammad just rewrote the Old and New Testament's 500 years later, I mean, the idiots that believed him! ) were written as a way to explain to earlier people, how things happened, take Adam and Eve as an example. It's a way of saying we all have common ancestors, whether that is two people ( I'm inbred? Fuck you! ) or a single-celled organism bubbling in a pool of minerals and protein.
To say that life is a low-entropy mass is just not good enough, and to end it is terrible. Any problem can be solved, we should look forward to what we have in-store, what is going to happen, not just how we feel at a moment. Teenagers slitting their wrists with a razor for attention = genes we don't need on planet Earth, so I rate suicide might just be a good thing. You know, if you are so stupid that you cannot see a use or future for yourself, society doesn't REALLY need you or the genes that make you that way. Lighten up and live, motherfucker!
