The problem isn't a lack of belief in God, in Science....the problem is a lack of belief in "MY God". Or rather, the God of the society the scientist is operating in.
The way some people behave - even here at FR - is a perfect example. Hardcore Christian Fundamentalists often get on threads that discuss any question of science more than 6,000 years in the past, and paint them as Godless lunacy that will land the unbelievers in hell. Should scientists believe in Adam and Eve? The six day creation? A boat so huge it would hold two of every living thing on earth?
No. Of course not. That would end science. But not believing in their God means that to Biblical Literalists, every scientist is a "Godless atheist".
So when ConservativeMind said "automatically believe in God", who's God? God, in general? Fundamentalist's God? Why would they believe in that? How much of the Bible would a scientist have to believe in, for you to consider them a "believer"? Why shouldn't they believe in Allah? Or follow Hinduism?
The question of God in Science is relative to the society asking the question. And frankly, it's usually only a question for the non-scientists. Many scientists believe in a God but find any attempt to qualify God absurd and won't address the question. Thus, they sound like atheists when, in fact, they actually understand how ignorant they truly are.
Modern science began with St Augustine. Science in fact came out of the Church and is analogous in some fundamental ways, especially in adopting dogma as the starting point. No wonder some accuse Science of being a Religion. It has a family resemblance and could hardly be otherwise since there aren’t a lot of alternatives.
