I think the next foray into the realm of science is to determine why religion is needed at all. If scientific testing is done in this capacity, then there is a religion vs. science because the goal would be to question religion as to its efficacy. The existing anthropological studies show that the evolutionary benefit of organized religion accrue to the priests/practitioners/intercessors between their personification of the unknown ("god(s)"), rather than to the believers, and that such benefits are large. Evolutionary psychology sees personification as a normal developmental stage in human cognition, so the institutionalizing of such inevitable beliefs as our intelligence grew up, so to speak, to the levels we now consider average for adults, was advantageous compared to societies where such beliefs weren't institutionalized. Thus it allowed for the development of the large city-state we now also call average for humans, despite its relative novelty. The problem is, we really aren't city folk, and we do much better in far less crowded conditions, but then nobody would make any real money.
