When did the first people appear on earth?

In fact, there is no exact definition of when a person appeared. Scientists today argue about this. One thing is clear that “Homo sapiens” appeared about 50 thousand years ago. Before that, there were species that resembled something in between monkeys and humans, but it was still difficult to name a person. Primitive people had a distinctive gait from modern people, a more convex skull shape and much more body hair.
