There is a false dichotomy that most people believe in without even thinking about it: that either science is true, or religion (i.e. Christianity) is true, but not both. For example, according to reviews of "The Unbelievers," that movie implicitly assumes this false dilemma and rides that assumption throughout.
But that doesn't hold water. I am a scientist and a Christian, and far from internally being at odds with myself, the scientific (and engineering) knowledge I have strengthens my belief in God.
What's interesting is that oftentimes, atheists maintain their lack of belief in any god not for scientific or logical reasons, but for non-rational (emotional) reasons. Take the oft-quoted Aldous Huxley on Christian morals: "We objected to the morality because it interfered with our sexual freedom."
Or infamous atheist Thomas Nagel: "I want atheism to be true and am made uneasy by the fact that some of the most intelligent and well-informed people I know are religious believers. It isn’t just that I don’t believe in God and, naturally hope that I’m right in my belief. It’s that I hope that there is no God! I don’t want there to be a God; I don’t want the universe to be like that."
(Incidentally, these quotes support what I was saying a few days ago in regard to Objection 4.)
