In c.485BC, Parmenides, in his On Nature, amid his debates with Heraclitus and his "flux, fire, and change philosophy", argued that "being" was unbegotten and indestructible, and therefore a "void" (or vacuum) did not not exist.
In c.460BC, Leucippus, in reaction or opposition to Parmenides no void hypothesis, invented "atomic theory", which postulated that everything in the universe is either atoms or voids.
In 350BC, Aristotle renamed Parmenides unbegotten being and no void logic, into the "nature abhors a vacuum" idiom.
