This claim is based on the ancient kaläm cosmological argument, which has been used in recent years by theistic
philosopher William Lane Craig during his frequent debates on the existence of God and by many other theistic debaters who follow his lead. Craig states the argument as a simple syllogism (Craig 1979):
(1) Whatever begins has a cause.
(2) The universe began to exist.
(3) Therefore, the universe has a cause.
