Flexi Says: Pangaea existed and broke up long before humans evolved. Homo sapiens, the human species, have only existed for about 200,000 years. In fact, the oldest hominids date back only as far as 6-7 million years ago. Pangea existed between about 299 million years ago to about 180 million years ago, during the Paleozoic and Mesozoic eras. During this time, dinosaurs and other reptiles were the dominant animal groups.
