Where Do Atheists Come From?

Whether you're a believer in God or not, this is a very good article. But in the end I believe it just leaves more questions.
A good compendium to this article recently released.

My exit questions are: If the original author of the second article/study surmises that liberals and atheists are so much more intelligent. How come a) They have never really proved evolution beyond a shadow of a doubt, even after centuries of science? b) The current U.S. liberal government can't solve any problems (especially with their administration filled with "whiz-kids?" and c) How come all the scientists and Nobel laureates can't convince most people that climate change is actually caused by man? Even with their cherry-picked "evidence" and cover-ups?
