The document discusses the lost continent of Kumari Kandam, which was located south of present-day India extending from Kanyakumari to parts of Madagascar and Australia. Rising sea levels due to melting ice sheets submerged the continent around 12,000 years ago. Archaeological evidence suggests the Tamil civilization in Kumari Kandam predated the earliest known civilizations of Mesopotamia and the Indus Valley, making it one of the earliest in the world. However, most evidence of this lost civilization was swallowed by the rising seas.
