Creatio ex nihilo
Creatio ex nihilo (Latin for "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 Ex nihilo nihil fit or "nothing comes from nothing", which means that all things were formed from preexisting things; an idea by the Greek philosopher Parmenides (c. 540 – c. 480 BC) about the nature of all things, and later more formally stated by Titus Lucretius Carus (c. 99 – c. 55 BC).
