" The emergence of the first large settlements triggered a seismic shift in religious life. Seeking to explain the catastrophes suddenly befalling us, we began to believe in vengeful and omnipotent beings, in gods who were enraged because of something we’d done. A whole clerical class was put in charge of figuring out why the gods were so angry. Had we eaten something forbidden? Said something wrong? Had an illicit thought?37 For the first time in history, we developed a notion of sin. And we began looking to priests to prescribe how we should do penance. Sometimes it was enough to pray or complete a strict set of rituals, but often we had to sacrifice cherished possessions–food or animals or even people. "
