In Greek mythology, for example, everything began when Uranus the Sky-Father and Gaia the Earth-Mother produced offspring; Uranus, however, turns out to be a tyrannical sort of father-god and is eventually overthrown by his son Kronos, who once again turns out to be a bad sort, and is overthrown in turn by his son Zeus, who is not much better, though about as good as most Greek gods were liable to get.
