Quoting scientists has as much value to me as quoting the Bible (or Harry Potter books). My atheist position isn't based on what people say (or are interpreted to saying), but on what they can prove. If Stephen Hawking tomorrow said "there is a God!" it would not matter to me one bit. He would still need to provide demonstrable evidence that is not personal revelation or a feeling or guess.
Lately, I have found that the key argument for theism seems to boil down to an the inability to be ok with "we don't know" and instead fill the gap of knowledge with "because...God". "We don't know" followed by "let's find out" seems to be more productive. Not sure how "because God" benefits anyone.
