Creatio ex nihilo

Creatio ex nihilo (Latin, 'creation out of nothing') is the doctrine that matter is not eternal but had to be created by some divine creative act. It is a theistic answer to the question of how the universe came to exist. It is in contrast to creatio ex materia, sometimes framed in terms of the dictum ex nihilo nihil fit or 'nothing comes from nothing', meaning all things were formed ex materia (that is, from pre-existing things).
