Se non ci fosse Dio non ci sarebbero gli atei. Chesterton

Atheism is the supreme example of a simple faith. ... The truth is that the atmosphere of excitement by which the atheist lives, is an atmosphere of thrilled and shuttering theism, and not of atheism at all; it is an atmosphere of defiance and not of denial. Irreverence is a very servile parasite of reverence; and has starved with its starving lord. After this first fuss about the merely aesthetic effect of blasphemy, the whole thing vanishes into its own void. If there were not God, there would be no atheists. ("Where All Roads Lead," Collected Works, vol. 3 [San Francisco: Ignatius Press, 1990] 37-38).
