Cosmological Argument

Aquinas's argument for the existence of God. Says that God is the First Mover (someone had to set things in motion, i.e. celestial bodies) and First
Cause (causation in general), and uses Contingent Existence (continued existence is always dependent on something else, nothing is self-existent except
God), Gradation (hierarchy, morals, levels of good
and bad), and the Teleological argument (if there is
a design, there must be a designer).
