"Mythology is the study of whatever religious or heroic legends are so foreign to a student's experience that he cannot believe them to be true....Myth has two main functions. The first is to answer the sort of awkward questions that children ask, such as: 'Who made the world? How will it end? Who was the first man? Where do souls go after death?'...The second function of myth is to justify an existing social system and account for traditional rites and customs."
