Edited sentence: Among the settlements were the major urban centres of Harappa, Mohenjo-daro (UNESCO World Heritage Site), Ganweriwala, Kalibangan, Dholavira, Lothal and Rakhigarhi.Rao (Shikaripura Ranganatha Rao) suggested that Indus Language has roots in proto Indo-Iranian Language groups and he has tried to read the language as old Sanskrit.Renowned Indian archeologist, S.Reserches indicate that Sarasvati River dried up around 2000BC due to sesmic activity resulting major tributaries like Sutlej and Yamuna changing their path and it is argued that due to this, the Civilisation started declining, as several hundreds of villages and towns were forcibly deserted and people started migrating towards southern and eastern places, especially towards Gangetic plains.The civilization is sometimes referred to as the Indus Ghaggar-Hakra civilization or the Indus-Sarasvati civilization by certain Hindutva groups as well as some researchers/writers, which is partly based on theories of Indigenous Aryans and the Out of India migration of Indo-European speakers.The fact that more than 1000 Harappan sites are found on the dried up river bed of Gaggar-Hakra (which is also called Sarasvati River) also gives credence to this theory
