Dawkins selects these myths from throughout the world, including Babylonian, Judeo-Christian, Aztec, Maori, Ancient Egyptian, Australian Aboriginal, Nordic, Hellenic, Chinese, Japanese, and other traditions. Chapter 9 ("Are we alone?") includes contemporary alien-abduction mythology; Chapter 4 ("What are things made of?") omits mythology altogether as Dawkins says that really small phenomena were unknown to primitive peoples prior to the invention of advanced optical magnification equipment, any texts they believed to be divinely inspired having failed to mention such useful knowledge as beyond human experience at the time. Dawkins also revisits his childhood and recalls his initial thoughts on these various phenomena or those thoughts expressed by his young contemporaries.
