65 million years ago - Extinction of the Dinosaurs
Why was the extinction of the dinosaurs so important?
I think that the extinction of the dinosaurs was a vital event in history because if they hadn't died, we may not be here. Even if humans did fill the earth while dinosaurs were alive, humans would not have been around for too long. Of course, nobody actually know why dinosaurs lived on the earth, but their extinction was a very important event in history.
