According to a PBS website, about 165 million years
(From about 230 million years ago to about 65 million years ago ... for a duration of 165 million years.)
"Dinosaurs existed between 230 million years ago and 65 million years ago, but none of the known dinosaur species existed for this entire time period. Throughout the group's existence, individual dinosaur species were evolving and going extinct. Some species diverged and gave rise to other species, while others disappeared. A mass extinction event at the end of the Cretaceous period, 65 million years ago, ended the reign of dinosaurs on Earth. Recently, many scientists have come to the conclusion that, while dinosaurs may have disappeared, one dinosaur lineage had evolved into birds long before the extinction event that wiped out the other dinosaurs -- and so, in a sense, dinosaurs are still around today.

The last dinosaur died about sixty-five million years ago. The first human came into existence less than 200,000 years ago. Adam and Eve are fictional characters who never actually existed - a literary device, nothing more.

Actually in 2014 the scientists started saying that it was the dinosaurs death anniversary So now instead of 65 million years ago it is now 66 million years ago.

Clearly birds are dinosaurs in any objective analyses, so they lived from about 250 million years to present.
