Why do you say "scam", when I am sourcing statistics from secular governments? You wont find any country in the entire world where nonbelievers have enough children to atleast replace their own numbers. In such cases evolution theory prescripts extinction, no?

Indeed, atheist scientists do believe there is such thing as "religious gene", thats what you are asking right? You do not care for what I think. So let atheists speak for themselves and how they admit, that religious will inherit the Earth.

Already wrote, that I see convergence between science and religion as both complement each other in description of natural phenomena and Gods will. One from material, the other from spiritual perspective.
