REALITY
Dinosaurs died out 65 million years ago. Fully modern humans (Homo sapiens) have existed for about 100,000 years and they have occupied the Americas for about 12,000 years. Humans missed the dinosaurs by 64.9 million years! The first people in the Americas hunted big animals such as mammoths and mastodons, and they also gathered plants.
