World is a common name for the whole of human civilization, specifically human experience, history, or the human condition in general, worldwide, i.e. anywhere on Earth. In a philosophical context it may refer to: (1) the whole of the physical Universe, or (2) an ontological world. In a theological context, world usually refers to the material or the profane sphere, as opposed to the celestial, spiritual, transcendent or sacred. The "end of the world" refers to scenarios of the final end of human history, often in religious contexts. World history is commonly understood as spanning the major geopolitical developments of about five millennia, from the first civilizations to the present.
