Atheism versus Theism

Alright, I want a good, clean fight.  Simply state your side, your argument/counter-argument/comment and whatnot.  I'm not trying to troll this, just wanting a good debate, so let's have one. (Atheist by the way)

atheism doesn't distinguish from religion in any appreciable manner.  'god' becomes the universe, 'religious rules' become scientific laws.  i mean if we're happy with that, kudos to us, but we're not really differentiating from religion.
