It’s an interesting question, but it’s also a question that’s not currently ok. Based on human fossil speculation, humans may have a history of 3 million years on Earth. At present, the earliest biological fossils discovered on the earth may be retrieved to 4.28 billion years (found in Quebec, Canada), which is more than 3 billion years ahead of the previous life of the Earth. Based on current research, there have been many great life booms and extinctions on the planet. Everyone knows recently that it was the great prosperity of the dinosaurs in the Jurassic period and the extinction at the end of the Cretaceous period.

The history of the Earth is relatively well-known and is taught at universities. I used to teach this course. The Earth formed about 4.55 billion years ago and life started soon afterwards. The oldest fossils found so far are about 3 billion years old, but new information becomes available almost daily from many investigators world-wide and this date may change. The oldest human skeletons, artifacts, etc are about 5 million years old. The development of humans passed through many stages, all supported by actual human skeletons found in many places. Our species, Homo sapiens (smart human) started about 100,000 years ago in Africa and spread around the world.
