I think one of the most clinching of the evidence for OIT is how the Rig veda describes the geography of India, including the Indus-Saraswati river as a thriving and mighty river, which dried up in 2000BCE. Therefore strongly suggesting the Vedic people were already present in India before 2000BCE, long before the proposed invasion, and thus putting the Vedic people in the same phase as IVC.
Now this makes a lot of sense to me because the traditional Indian texts which date back history going back 10,000 years and beyond, record in 3000BCE an urban civilisation that matches the description of the IVC. This is the period when the Mahabharta war took place and Krishna was said to live.
Finally, we have evidence of astronomical configurations described in the Vedas, some which could not have taken place any earlier than 6000BCE.
Another very important point that needs to be discussed is the translation of the Rig Veda itsef, which will tell us a lot about the culture of the Vedic people. According to the Aryan invasion theory, the Vedic people are nomadic, barbarian people who worship nature gods that spread through invasions, and the Rig Veda has been translated using this assumption. In order to translate therefore the Vedic Sanskrit, a comparative linguistic method is used, by comparing Sanskrit words to other Indo-European words to translate it historically. However, even when you use this method, many hymns in the Rig Veda are strongly consistent with the later mystical and yogic philosopphies.
However, if you use the the standard translation methods of the Vedic people, using their etymologies, grammar and dictionaries, the Vedas are perfectly consistent with mystical and yogic philosophies, and everything that we find later is found is germinal form in the Vedas. It is also clear that the Vedic authors practice Yoga, because the Vedic mention the practices of “tapasya” which can mean meditation.
In summary, if we look at the empirical evidence, the history as recorded in Indian texts and the readings of the Veda as it was read by Indians for thousands of years, there is a convergence of evidence. This strongly suggests Indian history as recorded by the Indians is accurate. Now, what is most interesting, is how colonial scholars decided to disregard India’s historical records and its traditional scholarship, just because it contradicted the historical narrative they wanted to construct. I thus think Aryan invasion theory is basically a myth that European colonizers fabricated for political agendas. They have to a large part been very successful in rewriting Indian history, as this myth has been represented as fact for 200 years. However, current scholarship, which is based on secular, objective and global standards, can see Aryan invasion theory for what it is now, and are revising Indian history to represent it more accurately.
