How long have humans been on Earth?

Answer: Modern humans that is Homo sapiens have been on Earth for approximately 200,000 years.

The oldest hominins are thought to have appeared as early as 7 million B.C.E., the earliest species of the Homo genus appeared around 2 million to 1.5 million B.C.E., and the modern humans Homo sapiens appeared around 200,000 years ago.

The emergence of Homo sapiens is associated with the Middle Paleolithic period, marking the beginning of anatomically modern humans. The exact timeline of human evolution involves the transition from earlier hominin species, such as Homo erectus and Homo habilis, and the development of Homo sapiens.

Evidence suggests that Homo sapiens first appeared in Africa and gradually migrated to other parts of the world. Archaeological findings, including tools, artwork, and skeletal remains, contribute to our understanding of human evolution and migration patterns.

While Homo sapiens have existed for around 200,000 years, the span of human civilization, characterized by agriculture, written language, and organized societies, is relatively recent, with the earliest civilizations emerging around 6,000 to 7,000 years ago in areas like Mesopotamia and the Indus Valley.
