The religious philosophers, over the centuries have tried to establish the existence of God and have come up with numerous arguments .Major arguments about His existence are Cosmological, Ontological, Teleological and the Moral Law Argument. The Cosmological Argument comes from the Greek word ‘cosmos’, which means the world. The Cosmological argument states that the universe could not have existed by its own, there must have been some cause that would have made the universe and that cause is God. The Teleological argument is from the word ‘teleo’ that means design or purpose. As the universe evidences great complexity of design, the great designer, the God must have designed it. The Moral law argument proposes that the moral Law and Order in this world is alive and exists because of God who has bestowed human beings with this understanding of morality.
According to the Ontological Argument, the God is the greatest being, imaginable, one of the aspects of greatness and perfection is his existence or in other words as God can be conceived that means he exists. Twelfth century theologian and philosopher Anslem developed this argument about God’s existence. This argument proves about the existence of God through abstract reasoning. Descartes in his Meditation 3 proposes about the Ontological existence of God .His Meditation 3 questions about the existence of God and his analysis is devoid of any scientific proof and religious arguments.
