Creation "ex nihilo" (Latin "out of nothing"), also known as "creation "de novo"", is a common type of mythical creation.
"Ex nihilo" creation is found in creation stories from ancient Egypt, the Rig Veda, the Bible and the Quran, and many animistic cultures in Africa, Asia, Oceania and North America.
The Debate between sheep and grain is an example of an even earlier form of "ex nihilo" creation myth from ancient Sumer.
In most of these stories the world is brought into being by the speech, dream, breath, or pure thought of a creator but creation "ex nihilo" may also take place through a creator's bodily secretions.
The literal translation of the phrase "ex nihilo" is "from nothing" but in many creation myths the line is blurred whether the creative act would be better classified as a creation "ex nihilo" or creation from chaos.
In "ex nihilo" creation myths the potential and the substance of creation springs from within the creator.
Such a creator may or may not be existing in physical surroundings such as darkness or water, but does not create the world from them, whereas in creation from chaos the substance used for creation is pre-existing within the unformed void.
The best-known example of a creation myth is the one found in the Hebrew Bible.
