Did we evolve to believe in God?

Religion and evolution mix like water and oil, they just don't seem to get along. But is it possible, we evolved to have religion?

Recently, a study published in the Journal, Social Cognitive and Affective Neuroscience, examined how a certain part of the brain is linked to belief in God. The study used 39 college undergraduates who were all religious and politically moderate. They were split into two groups. The first group had their posterior medial Frontal Cortex(pmFC) temporarily inhibited with pulses from a transcranial magnet. The second group got a similar treatment but with the magnet turned down, so it didn't actually affect how their brains worked.

The participants were first primed with the discussion on death and then asked whether they believed in various aspects of religion(the devil, hell, heaven, God etc). Those who had their brains inhibited, reported believing in all that almost a third less often than the students in the uninhibited group.

The conclusion the researcher drew, is religion Could be a method for overcoming an ideological problem. According to the researchers, the pmFC they were tinkering with, is used for solving concrete problems. The pmFC keeps us making choices that are consistent with ones made in the past. Maybe this part of the brain along with helping us solve problems, preserves how we've learned to solve them before and so keeps religious beliefs rigid. What are your thoughts?
