I'm just pointing out the curious situation wherein both atheism and theism have been live menu options for roughly the same length of time in the history of human thought and yet atheists have never had much luck persuading their fellow primates, sitting around the campfire, that the God conclusion should be renamed the God delusion.
But they have. Not in most of the world, where powerful men made belief in gods compulsory, and persuading your fellow primates would get you put to death. But there's a quarter of the world by population where for thousands of years the ruling ideology has been secular -- focused on man's duties not to supernatural beings but to his fellow man -- and the officials who were empowered to put men to death for speaking unapproved ideas typically cared not a whit whether their subjects believed in gods. Today we can see the result.
