The period before human civilization began is called prehistory. Prehistory can be divided into several periods. It is divided into three periods: the Paleolithic (Old Stone Age), the Mesolithic (Middle Stone Age), and the Neolithic. Our early human ancestors evolved around 300,000 BC and used stone tools to hunt, gather, farm, and produce food, creating the basis for human social civilization. Human society evolved in Africa, and early humans first migrated from Africa to Asia between 1.8 and 2 million years ago. They entered Europe between 1 and 1.5 million years ago. Modern humans inhabited most of the world much later. Humans first migrated to Australia 60,000 years ago and to the Americas about 30,000 years ago.
The study of prehistory is important because it provides crucial insights into the origins and evolution of human and cultural and social organization, examines the lives of early human communities before the development of writing systems, and fundamentally reveals the foundations of modern civilizations, and allows us to understand how humans adapted and innovated in response to environmental challenges throughout history, including the emergence of agriculture, animal domestication, and complex social structures.
The prehistory of Sri Lanka dates back to the Mesozoic Era, i.e. 300,000 years ago, in the Bundala region. The Balangoda region has also yielded a 30,000-year history of Balangoda Man and the Kitulgala Beliden. In the Dambulla region. Prehistoric excavations in Sri Lanka have revealed that Sri Lanka had a developed prehistory, as evidenced by the discovery of megalithic tombs. Accordingly, the Daraniyagala Foundation hopes to play an investigative role in the prehistory of Sri Lanka.
