There is no proof that Zeus exist. I do agree with the first answer that there is no proof that he exists but in Roman times Zeus was Jupiter. (he was not named after the planet, the planet was named after him.)
Dinosaurs first appeared during the Triassic period, approximately 230 million years ago. This era marked the beginning of the Mesozoic Era, often referred to as the "Age of Dinosaurs." The earliest known dinosaurs include species such as Eoraptor and Herrerasaurus.
The first non-avian dinosaurs appeared around 230 million years ago, give or take a few million years, and they became extinct 65.5 million years ago. But another group of dinosaurs (avian dinosaurs or birds) still exist.
