I do believe there is evidence, but ultimately even if God didn't exist I'd rather pretend He did. Even if religion is devoid of warmth, it's still better than atheism which is devoid of even the idea of warmth.
Reality becomes nothing but a big game. What would I do, go on a drinking binge, have an open relationship, go psych myself up with a bunch of humanists at a rally, sit on the beach and masturbate about my own beautiful mortality? Still can't hold back that eternal night.
When there's no objective meaning, then nothing really matters.
I think you (and many other people) are using religion as a moral and existential crutch. Why should "nothing matter" if there is no god? It matters that I want to live my life to the fullest. It matters that I love my family. It matters that I am anticipating having a good breakfast tomorrow morning. It matters that I care about other people. I don't need religion or any higher philosophy for this. I don't know of many depressed, nihilistic atheists. As I said in a previous post, morality is a result of evolution. It comes from within us and not from some divinely ordained commandments. Your life is what you make of it. It's up to you to find meaning in life. You don't need to hold on to the apron strings of "God" in order to do so. It's sad that you feel you are so incompetent to find meaning in life on your own that you would rather believe in an untrue religion than go without religion. By saying so, you are implicitly admitting that morality and meaning can come from people rather than from God - the people who invented the religion you would believe in out of necessity would also invent the "meaning of life" you seek within that religion.
Well, the truth is that this argument about 'using your head' works as badly for religion as it does for politics. After all, most people will say that they use their 'heads' to decide what political party to join... and there are how many?
Even science goes through changes in terms of its theories and assumptions. My grandfather remembered when pharmacies routinely filled prescriptions containing mercury, and now we treat it as a high-level toxin. These changes are all made by men who, in their time, were very much using their 'heads' and also very wrong.
So, now we are told that there is no God and that the Big Bang started it all... except no one has figured out how the bang started and how a bang made atomic particles out of nothing.
Yes, that makes loads of sense to me! Cool story, bro!
If you want to be serious and really use your head, try this: remove Christianity from history, then close your eyes and think about how the world would be right now. If you look on the influence of Christianity on history, you will see that it has made far more positive contributions than negative.
Science does change, but it has managed to prove a great deal of things. A lot of theoretic models constructed by scientists (atomic theory, evolution etc) have been proven to be fact. You, on the other hand, don't seem to offer much by way of evidence that God exists, mainly questionable moral arguments that prove nothing.
The big bang didn't "create" atoms (or rather the elements that make up atoms). As I said in my first post, science believes that the substance of the universe was never created but always existed, and just changes its form (when you think about it, you exempt the creator that you believe in from the necessity of being created that you believe in, so why shouldn't I believe that something always existed and no new substance was ever created?)
As for the "positive contributions" of Christianity, that is a highly subjective issue. One way or another, I don't think you need a church or a religion to do good. Alcoholics Anonymous is not a religion, for example, nor are the United Nations. As society evolves away from religion, it will find, as it has been finding already, secular ways of organizing people for the greater good of society.
A note to Achronos - I don't follow atheism because it's a "fashion", just as I'm sure you wouldn't be Orthodox if it were "fashionable" just to be fashionable yourself. I simply believe that belief in God lacks substance in fact.
