Christopher Hitchens, writing in The Portable Atheist: Essential Readings for the Nonbeliever:
Religion invents a problem where none exists by describing the wicked as also made in the image of god and the sexually nonconformist as existing in a state of incurable mortal sin that can incidentally cause floods and earthquakes.
How did such evil nonsense ever come to be so influential? And why are we so continually locked in combat with its violent and intolerant votaries? Well, religion was the race’s first (and worst) attempt to make sense of reality. It was the best the species could do at a time when we had no concept of physics, chemistry, biology or medicine. We did not know that we lived on a round planet, let alone that the said planet was in orbit in a minor and obscure solar system, which was also on the edge of an unimaginably vast cosmos that was exploding away from its original source of energy. We did not know that micro-organisms were so powerful and lived in our digestive systems in order to enable us to live, as well as mounting lethal attacks on us as parasites. We did not know of our close kinship with other animals. We believed that sprites, imps, demons, and djinns were hovering in the air about us. We imagined that thunder and lightning were portentous. It has taken us a long time to shrug off this heavy coat of ignorance and fear, and every time we do there are self-interested forces who want to compel us to put it back on again.
By all means let us agree that we are pattern-seeking mammals and that, owing to our restless intelligence and inquisitiveness, we will still prefer a conspiracy theory to no explanation at all. Religion was our first attempt at philosophy, just as alchemy was our first attempt at chemistry and astrology our first attempt to make sense of the movements of the heavens. I myself am a strong believer in the study of religion, first because culture and education involve a respect for tradition and for origins, and also because some of the early religious texts were among our first attempts at literature. But there is a reason why religions insist so much on strange events in the sky, as well as on less quantifiable phenomena such as dreams and visions. All of these things cater to our inborn stupidity, and our willingness to be persuaded against all the evidence that we are indeed the center of the universe and that everything is arranged with us in mind.
