Thomas Aquinas adapted Aristotle and Avicenna's thinking to form his cosmological argument in which he states that the universe is the result of a 'first cause' that is itself uncaused, and this ultimate cause according to him, is God. The premise of his argument basically states that every thing that was once non existent has a cause. Since, according to the second premise -something that is finite and dependent (contingent) cannot create itself. In his third premise Aquinas stated that a causal chain cannot stretch back into eternity. This is why Aquinas argues --there must be a first cause-(God)-or there must be something that is not an effect. Other cosmological veterans speculating about God's existence - (like Aquinas) take the 'first cause' to be 'God'. Aquinas's argument is based on the fact that God has to exist due to the fact that the universe needs a cause to explain its existence. This cause is furnished by the concept of the creation of the universe by a supernatural being outside it, and this being is assumed to be God.
