Fantasy is make-believe. We make something up and then we believe it in order to make it exist. However, in some contexts, the make-believe is relegated to the realm of mere ‘play’ (as opposed to the ‘real’), but there’s no denying that make-believing is a crux of human civilisation – children naturally play make-believe games that steer them in their growth, adults use the hypothetical in their thought to make everyday decisions, and both children and adults rely on fantastical stories and myths to construct a common meaning that contributes to creating the world as we know it.
