The Grand Canyon was created by a river. In that sense, it has a 'creator', but do you believe that the creator must have consciousness, will, and intent? Is 'god' another name for a non-living, unconscious, natural process that initiated the big bang?
Of course this all takes us away from the intent of the thread, which I was hoping would stay focused on the role that atheists have in the US government. I don't hold christian beliefs against someone who is running for office, I vote the issues. Can all of the religionists here say the same thing about an atheist up for election?
