Too many things to reply to...
Forgive my poor writing, it's quite difficult to discuss such topics in my third language. I don't want to be aggressive, but I'm not always sure about how my words sound to you.
Maybe religion is just a cultural thing (yes, I live in the country of Rome), but I don't think that lack of belief is a guarantee of one acting fairly. As being a religious has not prevented people from do horrible things. As a note, today the campain is against the Catholic church. As for the data I know, there is no proof pedophilia has been more frequent among priests than among common people. Which is really sad from both sides, BTW.
I'm not trying to preach. I'm just claiming my right to believe and not being judged as a stupid by default. And I think that, maybe, I don't know history and many other things, but maybe many of you haven't seen what some "believers" do every day, without asking for anything, in the silence, to help other people (without lookin at their religion, race or other). Whether they do this for a prize after Death, or just because it's right, it's hidden in their hearts. But this must make us ask why they do this. Just as I find it extraordinary how so many people (Dave for example) spend much of their time to spread their passion for technics, helping other people to learn.
I hope it's clear that for me it's impossible to proof the presence of God. Even the reasoning of going back to the origin of all (up to the Big Bang... and before) doesn't proof anything. One could however call "God" what you call chance (what is the physical law behind the random happening of Big Bang?). All I want to say is there is no prior incompatibility between reason and belief ("heart"). As a parallel, I think all of you have been in love. That's not a rational condition, if you think of it, but you do (of course, it has its evolutional origins), and it's one of the most beautiful things in the world.
And if science has shown us one thing, it's how incorrect "the world of god" (a.k.a the bible, a.k.a *insert any other holy book) actually is, and what a joke anyone is who actually tries to interpret it and take it literally.
The religious emperor has no clothes.
The holy books were written by people thousands years ago, using their own language. I only (little) know the Bible, and of course there are interpretations and, worse, people taking it literally, but a message is there. Again, it's not reason. If you don't want to use your heart, too, OK, no problem for me. Just let me use it, unless I dont' hurt you, of course!
