Prehistory is the time before writing was invented, which ended around 3000 BCE in some regions. It covers a very long period of human history. This time is studied using physical evidence instead of written records.

Archaeologists examine fossils, tools, and cave paintings to learn about early humans. Famous examples include cave art in Lascaux, France, and stone tools found in Africa. Prehistory includes early human development and migration across continents.

This period lasted millions of years and is studied in archaeology and science. It helps explain how humans lived before recorded history began.
