When does a person begin to explore the planet?

Man began to explore the planet 3 million years ago. That is, a distant human ancestor, Australopithecus, began to do this. At that time, Australopithecus lived in Africa. Australopithecus themselves were engaged in gathering. In fact, they were still primitive and looked more like animals than intelligent creatures. But with the course of evolution, man developed. So about 40 thousand years ago, Homo sapiens appeared. At that time, he continued to develop the land.
