The Tamil people originated in South India and Sri Lanka over 200,000 years ago according to a Tamil dictionary project. Their language spread throughout areas of South and Southeast Asia. Tamil accounts describe a now submerged continent called Kumari Kandam that was the original homeland for Tamils. Archaeological evidence from sites in Tamil Nadu and Sri Lanka suggests human settlements dating back hundreds of thousands of years, supporting Tamil oral histories of ancient civilizations in the region. Geological features like Adam's Bridge between India and Sri Lanka also confirm connections between the areas in ancient times described in Hindu and Tamil legends.
