The Indus River begins at the Tibetan Plateau near Lake Mansarovar and ends at the Arabian Sea. The Indus River is 1,980 miles long.
the above is answer is not at all correct. its true that aryans came in 1500bc and they were very destructive in nature not like indus valley civilization who were always had constructive minds. the indus valley civilization existed from 2500bc to 1750 bc. that means before aryans came the indus valley civilization was already finished 250 years ago. there are some historians that say that the indus river was flooded and due to that the indus valley civilization came to an end but in reality it was not possible that a flood destroys the whole civilization which was extended from uttar pradesh in the west to jammu and kashmir in north and to maharashtra in west. the actual reason which is more relaible answer than any other is that the indus valley civilization got extinct due to ecological factors. environmental and climatic factors like drying up of rivers,deforestation,soil sanity etc led to the decline of the greatest civilization.

there are many theories on this like aryan invasion,drought,famine e.t.c but there are no proofs for these,they are just rumors.but according to UN's statement a powerful flood attacked indus valley civilisation bringing end to the world's first and most advanced civilisation.and i too have similar ideas as this is a place of powerful rivers like indus,ravi,saraswati,chenab,satluj,yamuna and according to some theories even ganges was flowing here.
It is a difficult question...looking at the records we can find three civilizations which existed about 7000-5000 BCE they were:Egyption or Nile valleyIndian or Indus valleySumerianIn all these three, Indus valley was most advanced ... trade existed between Indus and Sumerian. The Indus valley civilization mainly expanded around the Indus river. However if you look at Indian texts we will find that due to a gigantic explosion or fire(at the end of Mahabharata) all the civilizations died and river Saraswati also dried up.It is a difficut question...looking at the records we can find three civilizations which existed adout 7000-5000 BCE.
