A migration happened. Genetics is proof. The Rakhigarhi DNA studies proves this rather than discredit it. IVC started collapsing due to monsoon failures and possible death of river Saraswati. The "Indo Aryans" came and mixed with the IVC people.
@Shaitan people get triggered because some folks have a
"Unlike other places there is no such thing as Indian civilisation. Its just some place where a bunch of invasions took place" argument.
This leads to emotional folks on our side swinging the opposite way and coming up with theories based on nonsensical interpretations of Vedas. Move on. A better use of resources would be deconstructing cuckoo Dravidian theories involving lemuria. I mean there are friggin political parties based on that.
Man, that is what I am trying to say The mainstream Indian academia have already moved on, and they are moving on fast!! They are on to different topics now in relations to these movements, etc.. Many Indians on the web think there is some sort of conspiracy against India, etc. The most propaganda I've been seeing of late is from Indians themselves.
The migration and the mixing that occurred is unlike any in Indian history, the movement of people that occurred also is unlike any in Indian history - it completely dwarfs the affects of the Indo-Pak border migration that occurred. We, the whole subcontinent have shared lineage from these events and it's mind boggling.
And it's not as simple as they gave us civilization, but it was the blending of peoples coming together that made Indian civilization. All of the successful Indo-European civilization - Rome, Greece, Persia, and India were a blend of outside and local forces.
By the time Alexander the Great invaded Indo-European peoples of Persia, Scythia, and India all these groups diverged in significant ways. That was due to the mixing with local peoples, extreme adaption to the locality.
