Inaccurate. For example, a location on the perpetually-dark side of an object is shrouded in “night”, whereas the opposite side is always “daytime”. The argument there is simply: does day/night depend on axial rotation of said object, or does it include the personal transit of a viewer across the boundary and thus cause the rising/setting of the dominant light source by that alone?

Regardless, darkness is the default state of the known universe.
