The official establishment of the Indus Valley Civilization was during 3000 BCE where the northern part of Pakistan and India are located now. The evolution of civilization started with the farmers and the trading of the farmed goods, which was done around the river.
With the advancement in the field of agriculture and trade, the major cities and towns started being built. The most cities and towns built were on the central part of the river, where they were located in an agriculturally favourable way.
The people of this civilization started growing crops with the help of the water, and suitable landforms staying around the river and traded the grown crops and made their daily life run smooth.
