Si Dieu n’existait pas, il faudrait l’inventer. (If God did not exist, we would have to invent him).
-Voltaire
Yes, I believe one of the ramifications of the development of abstract reasoning capabilities by humans was the emergence of a whole slew of questions that were (and are) psychologically difficult. When a man can take a step back and contemplate the results of his observations, that he will one day die, too, and be no more, it’s a crisis. One of the most undeniable truths about reality is one of the most frequently and strenuously denied, that we will die, and that will be the end of the self, so far as we can tell.
Combine that with another aspect of our physiology – our stance of intentionality – and you have the hydrogen and oxygen needed to make the water of religious imaginations. Man has survived by seeing the world through the lens of intentionality; he hears a rustle in the bushes, and is alarmed, alert, given to bias his reaction toward a possible agent, predator or prey, rather than just a rustling of the wind. The penalties of a ‘false negative’ – thinking there’s no intentional threat there when there is – are severe; that’s an easy way to die. The penalties for a ‘false positive’ – thinking there’s a threat in the bushes when there is not – are relatively small, and so man is inclined to be “better safe than sorry” in detecting intentionality and design in the world around him.
That teleocentric disposition, combined with an ability to step back and imagine, to conjecture in the abstract, makes God and gods, demons and fairies, inevitable, even if there is a God (or gods).
I understand your point, and grant that of course, if God exists and creates man with a “God shaped hole in his heart” (I think that’s the phrase) that that would be a predicate for thinking about God, or at least being ready to hear about God or receive revelation from him. But many Christians I know, including myself in younger days, just could not fathom the idea that this huge facet of our collective psychology would be fundamentally illusory. Not just mistaken about particulars, but false from square one as a matter of existential reality. But the more evidence and analysis comes in on this, the more compelling the explanation that yes, the imagination of God is an emergent phenomenon from the develop of abstract reasoning and imagination itself.
