What do each of the myths in the nonfiction book, The World of Myth, have in common?

In every myth mentioned in "The World of Myth: An Anthology," there is an element of Earth Meets Sky. The basic premise behind the concept is that through myth, the mere mortal can reach into the heavens and be a part of the divine. It can also be seen as the potential meeting of the eternal and the temporal. This can be viewed in many different ways, but the basic idea remains the same.
