The cosmological argument is a metaphysical argument for the existence of God, or a first mover of the cosmos. It is traditionally known as an "argument from universal causation," an "argument from first cause," and also as an "uncaused cause" argument and sometimes referred to as the Kalam cosmological argument. Whichever term is used, there are three basic variants of this argument, each with subtle but important distinctions: the argument from causation in esse, the argument from causation in fieri, and the argument from contingency. The cosmological argument does not attempt to prove anything about the first cause or about God, except to argue that such a cause must exist. This cause is known in Latin as "causa sui."
Plato and Aristotle both posited first cause arguments, though each had certain notable caveats. Plato (c. 427–c. 347 BCE) posited a basic cosmological argument in The Laws (Book X).
He argued that motion in the world and in the cosmos was "imparted motion" that would have required some kind of "self-originated motion" to set it in motion and to maintain the motion. Plato also posited a "Demiurge" of supreme wisdom and intelligence as the creator of the cosmos in his work Timaeus.
For Plato, the demiurge lacked the supernatural ability to create ex nihilo or out of nothing. The demiurge was only able to organize the "anake." The anake was the only other co-existent element or presence in Plato's cosmogony.
Aristotle (c. 384–322 BCE) also put forth the idea of a first cause, often referred to as the "Prime Mover" or "Unmoved Mover" (the πρῶτον κινοῦν ἀκίνητον or primus motor) in his work Metaphysics. For Aristotle too, as for Plato, the underlying "stuff" of the universe always was in existence and always would be (which in turn follows Parmenides' famous statement that "nothing can come from nothing"). Aristotle posited an underlying ousia (an essence or substance) of which the universe is composed, and it is the ousia that the Prime Mover organized and set into motion. The Prime Mover did not organize matter physically, but is instead a Being who constantly thinks about thinking itself, and who organized the cosmos by making matter the object of "aspiration or desire". The Prime Mover was, to Aristotle, a "thinking on thinking," an eternal process of pure thought.
Cosmology, from the Greek: κοσμολογία (cosmologia, κόσμος (cosmos) world + λογια (logia) discourse) is the study of the universe in its totality, and by extension, humanity's place in it. Though the word cosmology is recent (first used in 1730 in Christian Wolff's Cosmologia Generalis), the study of the universe has a long history involving science, philosophy, esotericism, and religion (see cosmological argument, kalam cosmological argument). 
The Kalam cosmological argument is a version of the cosmological argument derived from the Islamic Kalam form of dialectical argument. It attempts to prove the existence of God by appealing to the principle of universal cause. Similar arguments are found in the theologies of Judaism (for example, in the work of Maimonides) and Christianity (for example in Thomas Aquinas's Summa Theologiae), where it is known as the "uncaused cause" or "first cause" argument.
