The Urantia Book (sometimes called the Urantia Papers or The Fifth Epochal Revelation) is a spiritual and philosophical book that discusses God, Jesus, science, cosmology, religion, history and destiny. It originated in Chicago sometime between 1924 and 1955. The authorship remains a matter of speculation. The authors introduce the word "Urantia" as the name of the planet Earth and are self-described as superhuman personalities delivering the book as a revelation.
The Urantia Foundation, a U.S.-based non-profit group, first published The Urantia Book in 1955. In 2001, a jury found that the English book's copyright was no longer valid after 1983. The English text is a public domain work in the United States.
