Harappan Civilization and Rigveda

A careful consideration of the evidence of the Rig Veda will lead to the conclusion that references it contains about people and their civilization may be taken to refer to the Harappan
The Discovery of Boghaz-Koi inscription (of 14^th century B.C.) mentioned Rig Vedic deities that the Rig Veda existed earlier and the culture migrated from India to Asia Minor in that early age.
The time period of the Rig Veda in its final form should be placed not later than about 3,000 B.C.

The geographical distribution of the Harappan sites can be seen in the light of Rig Vedic geography as well.
The geographical features, mentioned in the Rig Veda, confirms the extension of Vedic Civilization from Afghanistan in the north to Gujarat in the south, Ganga in the east to Kubha (Kabul) in the west.
The Rig Vedic culture was flourished in the area around the Saraswati river and its tributaries; more than 80% of the Harappan settlements are found around the Saraswati valley thus it was the main area of Harappan
The animals known to the Indus people are also known to the Rig Veda, including sheep, dog, buffalo, bull, etc.
The animals hunted by the Rig Vedic people were antelopes, boars, buffalos (gaur), lions, and elephants most of them were also familiar to the Indus people.

A Terracotta Figurine of Horse found from Lothal. The horse was an important animal in the Vedic period. Horse bones and terracotta figurines have been found at some Harappan sites as well.
Some of the religious practices of the Harappan people like worship of Pipal trees, bull, Siva-lingas are still followed by the modern Hindus.
Some terracotta figurines of women found at Nausharo still have vermillion in their hair-parting. Vermillion in the Hair Parting is the most precious and sacred symbol of married Hindu women even today.
A terracotta tablet from Harappa depicts the scene of Mahisa sacrifice, reminding us of Mahisasuramardini.
The Harappan people were aware of using ornaments like earrings, necklaces, bracelets, anklets, garlands, and jewels.
Rig Veda mentions the use of gold and ayas (copper). Ayas was used in making of vessels.
The above-discussed similarities found between the Rig Vedic and Harappan civilization have led to the conclusion that the Harappan civilization is the same as the Vedic civilization and the Aryans did not come to India from outside.
