An attempt to prove that God exists by appealing to the principle that all things have causes. There cannot be an infinite regress of causes, therefore, there must be an uncaused cause: God.
one of the three types of 'theoretical' proofs for God's existence, arguing that 'experience' in general provides us with 'knowledge' that God exists.
One of the traditional proofs for the existence of God. Derived from the word “cosmos” (world), the argument attempts to prove that the world requires the existence of God as its ultimate cause.
The cosmological argument is a metaphysical argument for the existence of God, traditionally known as an "argument from universal causation," an "argument from first cause," and also as an "uncaused cause" 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.
