Indus

Explanation:

Palaeolithic sites have been discovered in the Indus Valley in Pothohar, near Islamabad, the capital of Pakistan, with stone tools from the Soan culture. In the ancient region of Gandhara, also near Islamabad, evidence of caves inhabited 15,000 years ago has been discovered in Mardan.

It was also developed between 2300 and 1750 a. C. the culture of the valley of the Indus, a prehistoric culture that apparently did not get to know the culture of the Aryans and that knew several stages, from the 7000 a. C.

Most scholars believe that Gandhara tomb culture settlements of the first Indo-Aryans flourished in the Gandhara region from 1700 BC. C. until 600 a. C., when Mohenjo-Daro and Harappa had already been abandoned.
