Are you an atheist? If so, you are a living, breathing counterexample challenging the claim that humans need religion. You don't need religion, do you? You don't have a "god-sized hole in your heart" making you incomplete without god belief, do you? Of course not! Your very existence suggests that religion is not a basic human need, as least not a universal one.
Could it be true that some humans need religion? Sure it could. I am absolutely convinced that some humans think that they need religion; I'm far less certain that some actually need religion, but I am willing to consider the possibility. Maybe some humans do need religion. Do you? I didn't think so.
I'm not sure exactly how many atheists are alive today. One recent poll suggests that 13% of us identify as atheists. Given the stigma associated with atheism in some countries, I'd guess that there are far more of us than most people realize. I have no idea how to estimate how many atheists have lived throughout human history, but I'd guess the number would be a fairly big one. Lots and lots of counterexamples.
