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 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).
Creatio ex materia refers to the idea that matter has always existed and that the modern cosmos is a reformation of pre-existing, primordial matter; it sometimes articulated by the philosophical dictum that nothing can come from nothing.
In ancient near eastern cosmology, the universe is formed ex materia from eternal formless matter, namely the dark and still primordial ocean of chaos. In Sumerian myth this cosmic ocean is personified as the goddess Nammu "who gave birth to heaven and earth" and had existed forever; in the Babylonian creation epic Enuma Elish, pre-existent chaos is made up of fresh-water Apsu and salt-water Tiamat, and from Tiamat the god Marduk created Heaven and Earth; in Egyptian creation myths a pre-existent watery chaos personified as the god Nun and associated with darkness, gave birth to the primeval hill (or in some versions a primeval lotus flower, or in others a celestial cow); and in Greek traditions the ultimate origin of the universe, depending on the source, is sometimes Oceanus (a river that circles the Earth), Night, or water.
Similarly, the Genesis creation narrative opens with the Hebrew phrase bereshit bara elohim et hashamayim ve'et ha'aretz, which can be interpreted in at least three ways:
Though option 1 has been the historic and predominant view, it has been recently suggested (since the Middle Ages) that it cannot be the preferred translation based on strictly linguistic and exegetical grounds. Whereas our modern societies see the origin of matter as a question of crucial importance, this may not have been the case for ancient cultures. Some scholars assert that when the author(s) of Genesis wrote the creation account, they were more concerned with God bringing the cosmos into operation by assigning roles and functions.
Creatio ex nihilo is the doctrine that all matter was created out of nothing by God in an initial or a beginning moment where the cosmos came into existence. It has been suggested that ex nihilo creation can also be found in creation stories from ancient Egypt (the Memphite Theology), the Rig Veda (X:129, also known as Nasadiya Sukta), and many animistic cultures in Africa, Asia, Oceania, and North America. The third-century founder of Neoplatonism, Plotinus, argued that the cosmos was distinct from God but was instead an emanation from God. This idea was rejected by Christian thinkers of the time on the basis of the creatio ex nihilo concept, and was also later rejected by Arabic and Hebrew philosophers.
Although ancient near eastern cosmology is widely seen as invoking a process of creatio ex materia, occasional suggestions have been made that the concept of creatio ex nihilo can be found at least in some texts, including the Egyptian Memphite Theology and the Genesis creation narrative. Hilber has rejected these interpretations, viewing both as consistent with creatio ex materia, but instead suggests some passages in the Book of Isaiah, the Book of Proverbs, and the Psalms might indicate a notion of creatio ex nihilo. The cosmogonical doxologies of the Book of Amos also present a view of creation ex-nihilo.
One view is that the earliest statement articulating the concept of creatio ex nihilo is attributed to a Jewish text from ~100 BC, 2 Maccabees: "I implore you, my child, observe heaven and earth, consider all that is in them, and acknowledge that God made them out of what did not exist, and that mankind comes into being the same way" (2 Macc. 7:28). Others, however, have argued against interpreting Maccabees in this way. Other historians have disputed the presence of the doctrine of creatio ex nihilo among pre-Christian Jewish authors, on the basis of the sparsity of possible relevant texts in Jewish later to the concept, the large number of Jewish texts from this period which unambiguously posit creatio ex materia, and the general disinterest in creatio ex nihilo prior to medieval rabbinic writers.
In the first century, Philo of Alexandria, a Hellenized Jew, lays out the basic idea of ex nihilo creation, though he is not always consistent, he rejects the Greek idea of the eternal universe and he maintains that God has created time itself. In other places it has been argued that he postulates pre-existent matter alongside God. But other major scholars such as Harry Austryn Wolfson see that interpretation of Philo's ideas differently and argue that the so-called pre-existent matter was created.
Saadia Gaon introduced ex nihilo creation into the readings of the Jewish bible in the 10th century CE in his work Book of Beliefs and Opinions where he imagines a God far more awesome and omnipotent than that of the rabbis, the traditional Jewish teachers who had so far dominated Judaism, whose God created the world from pre-existing matter. Today Jews, like Christians, tend to believe in creation ex nihilo, although some Jewish scholars maintain that Genesis 1:1 allows for the pre-existence of matter to which God gives form.
Jewish philosophers of the 9th and 10th century adopted the concept of "yesh me-Ayin", contradicting Greek philosophers and Aristotelian view that the world was created out of primordial matter and/or was eternal.
Mainstream Christians believe that originally there was nothing except for a single, infinite and eternal God and that God alone brought all matter, energy, time, and space into existence out of nothing. That belief developed in the second century of the Christian era.
The doctrine of creation ex nihilo was also widely adopted in Christian circles from an early period. It received its first explicit articulation by Theophilus of Antioch in a work of his known as To Autolycus in a chapter titled Absurd Opinions of the Philosophers Concerning God.: "As, therefore, in all these respects God is more powerful than man, so also in this; that out of things that are not He creates and has created things that are" (2.4). Creation ex nihilo had become a fundamental tenet of Christian theology by the 3rd century. In late antiquity, John Philoponus was its most prominent defender.
In modern times some Christian theologians argue that although the Bible does not explicitly mention creation ex nihilo, it gains validity from the tradition of having been held by so many for so long; and others find support in modern cosmological theories surrounding the Big Bang. Some examine alternatives to creatio ex nihilo, such as the idea that God created from his own self or from Christ, but this seems to imply that the world is more or less identical with God; or that God created from pre-existent matter, which at least has biblical support, but this implies that the world does not depend on God for its existence. The notion of creatio ex nihilo also underlies modern arguments for the existence of God among Christian and other theistic philosophers, especially as articulated in the cosmological argument and its more particular manifestation in the Kalam cosmological argument.
Members of The Church of Jesus Christ of Latter-day Saints do not believe, as do traditional Christians, that God created the universe ex nihilo (from nothing). Rather, to The Church of Jesus Christ of Latter-day Saints, the act of creation is to organize or reorganize pre-existing matter or intelligence.
Most scholars of Islam share with Christianity and Judaism the concept that God is a First Cause and absolute Creator; He did not create the world from pre-existing matter. However, some scholars, adhering to a strict literal interpretation of the Quran such as Ibn Taimiyya whose sources became the fundament of Wahhabism and contemporary teachings, hold that God fashioned the world out of primordial matter, based on Quranic verses.
The Chandogya Upanishad 6.2.1 says before the world was manifested, there was only existence, one unparalleled (sat eva ekam eva advitīyam). Swami Lokeshwarananda commented on this passage by saying "something out of nothing is an absurd idea".
Stoicism, founded by Zeno of Citium around 300 BC, includes the belief that creation out of nothing is impossible and that Zeus created the world out of his own being.
The Big Bang theory, in contrast to theology, is a scientific theory; it offers no explanation of cosmic existence but only a description of the first few moments of that existence.
