According to various surveys, the numbers of religious nonbelievers alive today fall into a ballpark of 800 million to 1 billion, or a percentage of the world's population in the teens. This demographic explosion of nonbelief has only happened in the last century, whereas before the 20th Century humanity was nearly 100% religious.

You can look at it in another apposite way: The number of nonbelievers alive today is comparable to the population of the world about 200 years ago, so that the demographic standards of the early 19th Century, the planet is full of "infidels." This trend throws considerable doubt on the claim that we have "god genes" which make us crazy under the influence of certain kinds of myths.
