Religious children have harder time between fact and fiction

Yea I caught this article. It's pretty darn subjective to me and far from being a "controlled experiment". But the thing that made me laugh the most is that this article's roots stem from trying to prove that God doesn't exist. The exact same thing as trying to prove He exist's. What is that about trying to prove a false negative? So to me this study is just as bogus as creation science, i.e. NOT science at all.
