Zeus spent his days walking the earth, indulging in his depraved desires with many mere mortals.
"Zeus" is merely the moniker for a particularly notorious fallen angel--part of the group that, flung down from Heaven, proceeded to make themselves gods amongst men and couple with humans at a whim. The Olympians fashioned the myth of Chronos, the father they sought to kill, as part of a propaganda campaign against God the Father. Note that Chronos' eventual fate--hurled well below Earth and into the Underworld--mirrors that of their own vanquished mentor, Lucifer.
Tbf if Al Pacino is to be believed, John Milton is the Devil.
