It's just depends on from what perspective you look at the world from(from that thing you wrote reminds me of just depressed people, the first post) There's no meaning of life and we live because we just happen to live. We evolved from monkeys to very smart species. Don't get stuck on those toughts you just wrote(the first post) just live the life in the way you want and in the way you can. To be completely honest here, when somebody believes in "god" i just ask myself "why?" There is really no point of believing in god anymore imo because this ain't the the -0-1500 centuries anymore. They had to believe in something to not lose hope in those rough times why to continue, that there is something good after you try your best. And i'm pretty sure that there is not any kind of "afterlife" when you die. Think it from this perspective: where you were when you weren't born yet? That's right, in nowhere. It's just how human mind thinks it all, it just depends on that i think.

I respect all the religions in the world but this is just my point of view.
