paragraph_text: Existence
  
  The existence of God is a subject of debate in theology, philosophy of religion and popular culture. In philosophical terms, the question of the existence of God involves the disciplines of epistemology (the nature and scope of knowledge) and ontology (study of the nature of being or existence) and the theory of value (since some definitions of God include "perfection").
  
  Ontological arguments refer to any argument for the existence of God that is based on a priori reasoning. Notable ontological arguments were formulated by Anselm and René Descartes. Cosmological arguments, such as those described below, use concepts around the origin of the universe to argue for the existence of God.
  
  The Teleological argument, also called the ‘’argument from design’’, uses the complexity within the universe as a proof of the existence of God. It is countered that the fine tuning required for a stable universe with life on earth is illusionary, as humans are only able to observe the small part of this universe that succeeded in making such observation possible, called the anthropic principle, and so would not learn of, for example, life on other planets or of universes that did not occur because of different laws of physics. Non-theists have argued that complex processes that have natural explanations yet to be discovered are referred to the supernatural, called god of the gaps. Other theists, such as John Henry Newman who believed theistic evolution was acceptable, have also argued against versions of the teleological argument and held that it is limiting of God to view him having to only intervene specially in some instances rather than having complex processes designed to create order.
  
  The Argument from beauty states that this universe happens to contain special beauty in it and that there would be no particular reason for this over aesthetic neutrality other than God. This has been countered by pointing to the existence of ugliness in the universe. This has also been countered by arguing that beauty has no objective reality and so the universe could be seen as ugly or that humans have made what is more beautiful than nature.
  
  The Argument from morality argues for the existence of God given the assumption of the objective existence of morals. While prominent non-theistic philosophers such as the atheist J. L. Mackie agreed that the argument is valid, they disagreed with its premises. David Hume argued that there is no basis to believe in objective moral truths while biologist E. O. Wilson theorized that the feelings of morality are a by-product of natural selection in humans and would not exist independent of the mind. Philosopher Michael Lou Martin argued that a subjective account for morality can be acceptable. Similar to the argument from morality is the argument from conscience which argues for the existence of God given the existence of a conscience that informs of right and wrong, even against prevailing moral codes. Philosopher John Locke instead argued that conscience is a social construct and thus could lead to contradicting morals.
  
  Atheism is, in a broad sense, the rejection of belief in the existence of deities. Agnosticism is the view that the truth values of certain claims—especially metaphysical and religious claims such as whether God, the divine or the supernatural exist—are unknown and perhaps unknowable. Theism generally holds that God exists objectively and independently of human thought and is sometimes used to refer to any belief in God or gods.
  
  Some view the existence of God as an empirical question. Richard Dawkins states that "a universe with a god would be a completely different kind of universe from one without, and it would be a scientific difference." Carl Sagan argued that the doctrine of a Creator of the Universe was difficult to prove or disprove and that the only conceivable scientific discovery that could disprove the existence of a Creator (not necessarily a God) would be the discovery that the universe is infinitely old. Some theologians, such as Alister McGrath, argue that the existence of God is not a question that can be answered using the scientific method.
  
  Agnostic Stephen Jay Gould argued that science and religion are not in conflict and proposed an approach dividing the world of philosophy into what he called " non-overlapping magisteria " (NOMA). In this view, questions of the supernatural, such as those relating to the existence and nature of God, are non - empirical and are the proper domain of theology. The methods of science should then be used to answer any empirical question about the natural world, and theology should be used to answer questions about ultimate meaning and moral value. In this view, the perceived lack of any empirical footprint from the magisterium of the supernatural onto natural events makes science the sole player in the natural world. Stephen Hawking and co-author Leonard Mlodinow state in their 2010 book, The Grand Design, that it is reasonable to ask who or what created the universe, but if the answer is God, then the question has merely been deflected to that of who created God. Both authors claim, however, that it is possible to answer these questions purely within the realm of science and without invoking divine beings.
