Context: Evidence of human colonization in Sri Lanka appears at the site of Balangoda. Balangoda Man arrived on the island about 125,000 years ago and has been identified as Mesolithic hunter-gatherers who lived in caves. Several of these caves, including the well-known Batadombalena and the Fa Hien Cave, have yielded many artifacts from these people, who are currently the first known inhabitants of the island.

Balangoda Man probably created Horton Plains, in the central hills, by burning the trees in order to catch game. However, the discovery of oats and barley on the plains at about 15,000 BCE suggests that agriculture had already developed at this early date.

Several minute granite tools (about 4 centimetres in length), earthenware, remnants of charred timber, and clay burial pots date to the Mesolithic. Human remains dating to 6000 BCE have been discovered during recent excavations around a cave at Warana Raja Maha Vihara and in the Kalatuwawa area.


Question: Given this paragraph about the prehistory of Sri Lanka, what are the evidence for prehistoric human colonization in Sri Lanka?

The oldest prehistoric evidence of human colonization in Sri Lanka goes back to about 125,000 years to a man named Balangoda Man. He was a Mesolithic hunter-gatherer who lived in caves. Furthermore, human remains dating back to 6000 BCE have also been found in several cites in the country.
