Re: Pakistan: The True Heir Of Indus Valley Civilization – Analysis
Good Question. How do you know that the Indo-Gangetic plain was inhabited before the collapse of IVC? This is all I found… In the aftermath of the Indus Civilization’s collapse, regional cultures emerged, to varying degrees showing the influence of the Indus Civilization. In the formerly great city of Harappa, burials have been found that correspond to a regional culture called the Cemetery H culture . At the same time, the Ochre Coloured Pottery culture expanded from Rajasthan into the Gangetic Plain . The Cemetery H culture has the earliest evidence for cremation ; a practice dominant in Hinduism The earliest anatomically modern human remains found in South Asia date from approximately 30,000 years ago.[SUP][18]](India - Wikipedia )[/SUP] Nearly contemporaneous Mesolithic rock art sites have been found in many parts of the Indian subcontinent, including at the Bhimbetka rock shelters in Madhya Pradesh .[SUP][19]](India - Wikipedia )[/SUP] Around 7000 BCE, the first known Neolithic settlements appeared on the subcontinent in Mehrgarh and other sites in western Pakistan.[SUP][20]](India - Wikipedia )[/SUP] These gradually developed into the Indus Valley Civilisation ,[SUP][21]](India - Wikipedia )[/SUP] the first urban culture in South Asia;[SUP][22]](India - Wikipedia )[/SUP] it flourished during 2500–1900 BCE in Pakistan and western India.[SUP][23]](India - Wikipedia )[/SUP] Centred around cities such as Mohenjo-daro , Harappa , Dholavira , and Kalibangan , and relying on varied forms of subsistence, the civilization engaged robustly in crafts production and wide-ranging trade.[SUP][22]](India - Wikipedia )[/SUP]
During the period 2000–500 BCE, in terms of culture, many regions of the subcontinent transitioned from the Chalcolithic to the Iron Age .[SUP][24]](India - Wikipedia )[/SUP] The Vedas , the oldest scriptures of Hinduism,[SUP][25]](India - Wikipedia )[/SUP] were composed during this period,[SUP][26]](India - Wikipedia )[/SUP] and historians have analysed these to posit a Vedic culture in the Punjab region and the upper Gangetic Plain .[SUP][24]](India - Wikipedia )[/SUP] Most historians also consider this period to have encompassed several waves of Indo-Aryan migration into the subcontinent from the north-west.[SUP][27]](India - Wikipedia )[/SUP][SUP][25]](India - Wikipedia )[/SUP][SUP][28]](India - Wikipedia )[/SUP] The caste system , which created a hierarchy of priests, warriors, and free peasants, but which excluded indigenous peoples by labelling their occupations impure, arose during this period.[SUP][29]](India - Wikipedia )[/SUP] On the Deccan Plateau , archaeological evidence from this period suggests the existence of a chiefdom stage of political organisation.[SUP][24]](India - Wikipedia )[/SUP] In southern India, a progression to sedentary life is indicated by the large number of megalithic monuments dating from this period,[SUP][30]](India - Wikipedia )[/SUP] as well as by nearby traces of agriculture, irrigation tanks, and craft traditions.[SUP][30]](India - Wikipedia )[/SUP]
Source:wikipedia. Not sure if Gangetic plains were populated before Vedic period. In most places in India history begins with Iron age/Vedic period since historians and archeologists have not found remains to significantly conclude otherwise. It is almost as if humanity began with the Iron age here.
During recent excavation in Karachi, Sindh, many artifacts have been found much older than Moen Jo Daro. Karachi is a coastal area like Mumbai and they are not far from each other.
