Answer: Kanniyakumari
Notes: The Archaeological Survey of India recently found one of the earliest rock grooves in Kanniyakumari district, made during the Neolithic Age to sharpen weapons. The Neolithic Age, also known as the New Stone Age, was the last phase of prehistoric human development. It marked the shift from hunting and gathering to farming and animal domestication. This period began around 10,000 BCE during the Holocene Epoch. The Neolithic Revolution started in the Fertile Crescent in the Middle East and later spread to India and other regions.
