A deity or a god is a postulated or existent supernatural being, usually, but not always, of significant power, worshipped, thought holy, divine, or sacred, held in high regard, or respected by human beings. They assume a variety of forms, but are frequently depicted as having human or animal form. Sometimes it is considered blasphemous to imagine the deity as having any concrete form. They are usually immortal. They commonly have personalities and possess consciousness, intellects, desires, and emotions much like humans. Such natural phenomena as lightning, floods, storms, other "acts of God," and miracles are attributed to them, and they may be the authorities or controllers of every aspect of human life (such as birth or the afterlife). Some deities are asserted to be the directors of time and fate itself, to be the givers of human law and morality, to be the ultimate judges of human worth and behavior, and to be the designers and creators of the Earth or the universe. Some of these "gods" have no power at all—they are simply worshipped.
