Life, unlike stories, has no theme, no formal unity, and (to unbelievers, at least) no readily apparent meaning. That's why we want stories. No art form can hope to exactly reproduce the sensations that make up being alive, but that's OK: life after all, is what we already have. From art, we want something different, something with a shape and a purpose. Any departure a story might make from real-world laws against talking animals and flying carpets seems relatively inconsequential compared to this first, great leap away from reality. Perhaps that's why humanity's oldest stories are full of outlandish events and supernatural beings; the idea that a story must somehow mimic actual everyday experience would probably have seemed daft to the first tellers. Why even bother to tell a story about something so commonplace?
