The Guaraní people live in south-central part of South America, especially in Paraguay and parts of the surrounding areas of Argentina, Brazil, and Bolivia.
There exist no written records of the ancient myths and legends associated with the Guaraní people. The Guaraní language was not a written language until modern times, and, as such, the entirety of their religious beliefs is passed down through word of mouth only. As such, accounts of the various gods and related myths and legends can vary from one locale to the next, and the regional differences may be so extreme as to completely redefine the role a specific deity plays in the Guaraní belief system.
Although a large number of the indigenous Guaraní people have largely been assimilated into modern society and their belief system altered or replaced by Christianity (due in large part to the work of Jesuit missionaries in the 16th century), several of the core beliefs are still active in many rural areas in the Guaraní region. As a result, the myths and legends continue to evolve to this day.
The primary figure in most Guaraní creation legends is Tupã, the supreme god of all . With the help of the moon goddess Arasy, Tupã descended upon the Earth in a location specified as a hill in the region of Aregúa, Paraguay, and from that location created all that is found upon the face of the earth, including the ocean, forests, and the animals. It is also said that the stars were placed in the sky at this point.
