I read this one article once about how there is a part of the brain that registers religious experiences; basically lights up like a winter festival when people "feel god" and stuff. It is, not surprisingly, more developed in super religious or spiritual people. A few scientists were saying that this explained feelings of god, as it were.

Hm, I wonder how they got to that conclusion. I'd heard about the religious activity christmas tree but not about those particular implications. Brain lights up during activity, regardless of the activity's nature. For example in my synesthesia, when I am reading, my limbic brain would light up in perception of the different colors of letters but that doesn't mean that the letters aren't only black and white.

Do you have a link to that article?
