A world parents story is a type of creation myth that sees the world or universe as the original creator. It uses symbolic narrative to establish the world and nature as the origin of life. The sky and earth, or the sun and moon, are examples of main characters in this kind of origin story.
If I’m understanding the question it uses both metaphors and alliteration in the poem which is uncommon because most poetry uses typical one literary device and not multiples at the same time
