i think i posted earlier in this thread, but whatevs, my friends. bullshit there's no such thing as hope. Do you submit to the void or do you attack it? To paraphrase my earlier point: the void of set "purpose" in one's life is something to be grateful for, not something to angst about. It means that you can define purpose on your own, and that nothing is set in stone but stone itself. Humans are fated to die only because of the limits of our biological functions; we have the ability to concede to starvation if we wish, but we do not, except perhaps to make a political point--a point that is meaningful to us, God or not--or due to immense economic misfortune. Nihilism fails because to deny that something "is" means that it exists in some form, in thought or in being, and if thought exists, then something exists, don't it? You can say that that thought is temporary all you like but the thought still happened, to deny it is both stupid and cruel--see George Orwell's 1984 for the government that does that to perpetuate its existence. A lack of "God" does not equal a lack of spirit, whether that "spirit" is grounded upon biology or not, and it definitely doesn't equate to a denial that matter itself exists. The purpose of life is not merely to be happy, the purpose of life is a moot point: you have the freedom to live upon your own terms. Stop thinking about the purpose of individual life, focus upon the purpose of being-- to be, and by being, defy that boring, cold void. Even physical pain has a purpose--the brain's warning that the body must escape that source of pain, though the world's continuing destitution and irrational discrimination do not. But don't sit there and deny that you're sitting there, that you will have ever sat there, come the eons that may follow. The reason you feel it's pointless, that there is no hope, is because you're hopelessly deciding that it's pointless, and that's an error you shall most definitely live to regret.
Also Christianity isn't the only religion in the world, question some other ones now and then, or go ahead, make your own. Go ahead, start a cult. A cult which will exist and which will have existed. Atheism is actually quite a boring stance--we get it, there isn't a God, there's a hell of a lot else in the world to think about.
