Here's a quote, that I believe to be reasonably accurate, from Wikipedia: "Among the members of the National Academy of Sciences, 7% believed in God, 72.2% did not, and 20.8% were agnostic or had doubts" I don't really need to elaborate any more on that one, do I?
Yes, you do. The point you're trying to make is not clear. You seem to be offering this as evidence that "atheists flock to science" - but it's not evidence of that at all. It says nothing about atheists. However, it may say something about scientists. It may be evidence that scientists "flock" to atheism - but that's a totally different thing altogether, and has nothing to do with atheists flocking to science.
