WHO AND WHAT IS GOD

God is often conceived as the Supreme Being and principal object of faith. In theism, God is the creator and sustainer of the universe. In deism, God is the creator (but not the sustainer) of the universe. In pantheism, God is the universe itself. The concept of God as described by theologians commonly includes the attributes of omniscience (infinite knowledge), omnipotence (unlimited power), omnipresence (present everywhere), omnibenevolence (perfect goodness), divine simplicity, and eternal and necessary existence. Monotheism is the belief in the existence of one God or in the oneness of God. God has also been conceived as being incorporeal (immaterial), a personal being, the source of all moral obligation, and the "greatest conceivable existent". 

There are many names for God, and different names are attached to different cultural ideas about who God is and what attributes possessed. In the ancient Egyptian era of Atenism, possibly the earliest recorded monotheistic religion premised on there being one "true" Supreme Being and Creator of the Universe, this deity is called Aten. In the Hebrew Bible "He Who Is," "I Am that I Am", and the "Tetragrammaton" YHVH are used as names of God, while Yahweh, and Jehovah are sometimes used in Christianity as vocalizations of YHVH. In Arabic and other Semitic language, the name Allah, "Al-El," or "Al-Elah" ("the God") is used. Muslims regard a multitude of titular names for God, while in Judaism it is common to refer to God by the titular names Elohim or Adonai, the latter of which is believed by some scholars to descend from the Egyptian Aten. In Hinduism, Brahman is often considered a monistic deity. Other religions have names for God, for instance, Baha in the Bahá'í Faith,[Waheguru in Sikhism, and Ahura Mazda in Zoroastrianism.
