I won't dignify it with a link, but recently some scientists put some religious people in an fMRI machine and had them pray. Believe it or not, the "I'm interacting with someone" parts of their brains lit up (i.e. had increased blood flow).
Well, duh. What did they expect? Their brains to light up in the shapes of angels? Golden halos to appear on their screens?
It really doesn't matter what you believe, you should have expected this. If god exists, people interact with him as if he is a person. If god doesn't exist, but people think he does, they will interact with him as if he were a person. So when you stick people in an fMRI and find that they interact with him as if he were a person, why the hell do you think that is news? Now I have to listen to moronic atheists saying that god doesn't exist because science proved that people interact with him as if he were a person, AND I have to listen to moronic Christians saying god must exist because science proved they interact with him as a person.
BTW, they also had the people "pray" to Santa Claus, and those parts of their brains did not light up. Whoop-dee-freakin'-doo.
