The world is the planet Earth and all life on it,
including human civilization.[1] In a philosophical context,
the "world" is the whole of the physical Universe, or an ontological
world (the "world" of an individual). In a theological context, the world
is the material or the profane sphere, as opposed to the celestial, spiritual,
transcendent or sacred spheres. "End of the world" scenarios refer to the end
of human history, often in religious contexts.
