Language and storytelling arose as a means of creating and maintaining social ties. Tribes then spread across the planet, trading materials, goods, technology, information and stories, so it should not come as a surprise that our narratives are similar worldwide. As humans, we make up stories habitually in order to understand the universe, ourselves and others, but we can only do so within established narrative language (as we have seen) and (this is the new part) preexisting forms and genres.
