Sindhu-Saraswati civilization and Vedic Age
However, as the latest research on the presence of the Saraswati river shows, the nomenclature “Indus Valley or Sindhu Saraswati” Civilization is backed by serious evidence, further bolstered by the latest research on the existence of a mighty river Saraswati as described in the Rig Veda.
In a recent research paper, four scientists from different institutes in India published their findings after studying changes in sediment provenance over time along a 300 km stretch of the Ghaggar river basin. The researchers conclude that 80,000 to 20,000 years ago and 9,000 to 4,500 years ago (9-4.5 ka) the river was perennial and was receiving sediments from the Higher and Lesser Himalayas.
By a matter of sheer luck, the first site of the civilization was discovered in Harappa in the present day Pakistan, and led to the initial digs being focused on the Indus Valley.
However, as the exploration increased, it became clear the a significant number of the sites were present in the Saraswati valley and to its east.
