FACT: If evolution(per say) is true then humans could have evolved from more primitive creatures[lifeforms] (with no concept of God) to ultimately believe in GOD(s)... therefore the "meme" and memetic(Dawkins) of GOD is an evolutionary product.. Conflated to non belief in "a God" is memetically more primitive.. and under evolved..
The concept of God seems to be too abstract for Apes and many scientists.. God bless them they are doing the best they can evidently..
