Sex was pleasurable, sure, but survival was sweeter still.

Most of the monotheisms were tribal, pastoral, retributive religions that committed holocausts and built pyramids of skulls and conducted organized murder for a few thousand years, so there were lots of opportunities for one guy's god to fight some other guy's god. Each tribal religion claimed that its god was the One True God. Every prophet had his own idea about what that meant, of course, and as a result man was always being jerked around between different people's ideas of god, depending on who'd won the most recent war, or palace coup, or political battle.
"This meant mankind was always being asked to accept deities foreign to his own nature. I mean, if your prophet was sexually insecure, or if his later interpreters were, that religion demanded celibacy or repression or even hatred of women; if the prophet was a homophobe, he preached persecution of homosexuals; and if he was both lecherous and greedy, he preached polygyny. If he was luxurious, he preached give-me-money-and-God-will-make-you-rich; if he felt put upon he preached God-of-Vengeance, let's kill the other guy; and no matter how much well-meaning ecumenicists pretended all the gods were one god under different aspects, they weren't any such thing, because every prophet created God in his own image, to confront his own nightmares."

"Well, why didn't the silly Bloomians think of that?"
"Religion, I imagine, friend Chance. Religion serves to prevent thought in many cases, and I'd say it had done so here. They started with the presumption that anything as complex as the mill must exist for a good reason. Then they spent all their time inventing a good reason—and some god to be responsible for it—rather than looking for a sensible solution to their problem."
