If religions are a human construct our task is to find out why that might be the case. There is, after all, no agreed method by which its competing truth claims may be settled and the damaging divisions brought about in humanity by adherence to differing religious belief systems ameliorated.
Fortunately, as this presentation from Andy Thomson suggests, we are getting much much closer to an understanding of the cognitive mechanisms that have evolved in the human brain over evolutionary time that help to explain why humans are prone to (and will continue to), adhere to religious ways of thinking.
Knowing yourself is half the battle. The other half is changing it. I hope we can.
