What does nonexistence mean?
Nonexistence is the state or condition of not existing or being present. It is most often used in formal, academic, philosophical, or legal contexts, especially when discussing whether something—such as a deity, a proposed species, an undiscovered object, or matter itself—has any real existence. In ordinary speech, “does not exist” or “absence” is usually more natural, so nonexistence can sound abstract or argumentative. The word can refer both to a general condition and to a specific claim that a thing is unreal: one may speak of “the nonexistence of matter” or of “the nonexistence of a particular object.” Its uncompromising tone makes it useful for precise discussion, but it should not be treated as a synonym for insignificance. A nonexistent thing is absent, whereas an unimportant person may still exist. Overall, nonexistence is a compact noun for turning the existence of something into a subject that can be denied, proved, or debated.

Where does nonexistence come from?
Nonexistence was formed in English from the prefix non- and the noun existence, with the negating sense developing in the seventeenth century. Existence comes through Latin existentia from the present participle existens of existere, meaning “to stand out” or “to exist.” The same Latin root underlies forms such as existent, entity, and essence.
