Creation ex nihilo

Ex nihilo is a Latin phrase meaning "out of nothing". It often appears in conjunction with the concept of creation, as in creatio ex nihilo, meaning "creation out of nothing", chiefly in philosophical or theological contexts, but it also occurs in other fields.

In theology, the common phrase creatio ex nihilo ("creation out of nothing"), contrasts with creatio ex materia (creation out of some pre-existent, eternal matter) and with creatio ex deo (creation out of the being of God). Creatio continua is the ongoing divine creation.

The phrase ex nihilo also appears in the classical philosophical formulation ex nihilo nihil fit, which means "Out of nothing comes nothing".

When used outside of religious or metaphysical contexts ex nihilo also refers to something coming from nothing. For example, in a conversation, one might raise a topic "ex nihilo" if it bears no relation to the previous topic of discussion.

Ancient Near Eastern mythologies and classical creation myths in Greek mythology envisioned the creation of the world as resulting from the actions of a god or gods upon already-existing primeval matter, known as chaos.

An early conflation of Greek philosophy with the narratives in the Hebrew Bible came from Philo of Alexandria (d. AD 50), writing in the context of Hellenistic Judaism. Philo equated the Hebrew creator-deity Yahweh with Aristotle's primum movens (First Cause) in an attempt to prove that the Jews had held monotheistic views even before the Greeks. However, this was still within the context of creation from pre-existing materials (i.e., "moving" or "changing" a material substratum.)
