WHOSE BEEN ON EARTH THE LONGEST - DINOSAURS OR THE HOMO GENUS?

So who has been on this planet longer, dinosaurs or the human genus? Dinosaurs came about 230 million years ago and lived on Earth for 165 million years, becoming extinct 65 million years ago. The human genus came about 2.5 million years ago.


To understand who has lived on Earth longer, play with the idea that the time period from the beginning of the dinosaurs to today is compressed into a period of 365 days. In this context, the dinosaurs have lived from the 1st of January to about the 3rd week in September. Humans on the other hand have existed for only 1 day, the 31st of December. We have not occupied this planet for very long, and it is fascinating how much life has been here before us.
