God is the principal or sole deity in religions and other belief systems that worship one deity.[1]

God is most often conceived of as the creator and overseer of the universe. Theologians have ascribed a variety of attributes to the many different conceptions of God. The most common among these include omniscience, omnipotence, omnipresence, omnibenevolence (perfect goodness), divine simplicity, jealousy, and eternal and necessary existence. God has also been conceived as being incorporeal, a personal being, the source of all moral obligation, and the "greatest conceivable existent".[1] These attributes were all supported to varying degrees by the early Jewish, Christian and Muslim theologian philosophers, including Augustine of Hippo,[2] Al-Ghazali,[3] and Maimonides.[2] Many notable medieval philosophers developed arguments for the existence of God,[4] attempting to wrestle with the apparent contradictions implied by many of these attributes.


As of 2000, approximately 53% of the world's population identifies with one of the three Abrahamic religions (33% Christian, 20% Islam, <1% Judaism), 6% with Buddhism, 13% with Hinduism, 6% with traditional Chinese religion, 7% with various other religions, and less than 15% as non-religious. Most of these religious beliefs involve a god or gods.[29]
