Averroes lays out his views on the existence and nature of God in the treatise The Exposition of the Methods of Proof. He examines and critiques the doctrines of four sects of Islam: the Asharites, the Mutazilites, the Sufis and those he calls the "literalists" (al-hashwiyah). Among other things, he examines their proofs of God's existence and critiques each one. Averroes argues that there are two arguments for God's existence that he deems logically sound and in accordance to the Quran; the arguments from "providence" and "from invention". The providence argument considers that the world and the universe seem finely tuned to support human life. Averroes cited the sun, the moon, the rivers, the seas and the location of humans on the earth. According to him, this suggests a creator who created them for the welfare of mankind. The argument from invention contends that worldly entities such as animals and plants appear to have been invented. Therefore, Averroes argues that a designer was behind the creation and that is God. Averroes's two arguments are teleological in nature and not cosmological like the arguments of Aristotle and most contemporaneous Muslim kalam theologians.
