1. Cosmological Argument: Also called the argument from universal causation or the argument from contingency, the cosmological argument is probably the most well-known and well-loved among theistic apologists. The basic argument is that all effects have an efficient cause. The universe, and all that is in it, due to its contingent (dependent) nature, is an effect. Therefore, the universe has a cause…but that cause cannot be an effect, or one would have to explain its cause. Therefore, there must be an ultimate cause, an unmoved mover, an uncaused cause that began the process. This cause must transcend time and space in order to transcend the law of cause and effect. This transcendent entity must be personal in order to willfully cause the effect. This ultimate cause is God.
