Susan Reynolds said this quote

Storytelling began as a way for humans to relay information, from where to find food sources to the benefits of familial bonding, because fictional stories were the easiest way to memorize and communicate a complete set of information. We remember information best when it is delivered in the form of a plot, which is called 'semantic memory.' Stories still serve a definitive purpose and the stronger the purpose, the clearer the story.Fire Up Your Writing Brain
