What is the differences between old and new stonage?

The oldest culture of the world is Samma Soan Valley ( Salt Range & Kashmir ) in South Asia 0.5-2.5 million B.C. old. I had detailed discussion with aminent Scholar and liguistic expert Dani during the interview for decryption of Matured Harappan Scripts 1900-1300 B.C. bronze age civilization in South Asia. We have peking man bones and Ijwaka in Japan 0.1 million years old. The old stone age culture had humalike creatures living in caves using stone tools. The dress of tree leaves , the invention of fire and find the settlement may be termed as new stone age. In near east and far east , we have a old city under the sea at the coast of Indian Gujrat , a city near dead sea and Margarh sttlement in Gedrosia ( presenrt Baluchistan) , some settlements of Kotdiji culture in Indus Valley and old settlement in snake vallley Taxila belonging to Naga tribe.Most of the cites remain hidden due to lack of fund , high water level and other reasons hence true difference can not be outlined.
