I think "god centric" cultures in the dawn of humanity had better survival chances
First of all, I am more an atheist than a believer I am only a believer when my fears take control of all my thinking.
Funny that I found this thread since I was looking information to supports my theory that gods are hardwired in the brains of our ancestors, then somebody creates religion.
Imagine that you were in that times when you have so little control over nature, if you have a way to pass control of that elements to someone almighty then you can relax and function better that is why I think those who had the "god gene" survive.
