I do not want to start a flamewar but Indians should most certainly come out of the shoddy colonial scholarship and their control over Indology.
Horse,
Early British researchers claimed Harrapans (aroun 3500 BC) did not know horses and since Vedas rely so much on horses, clearly Vedas were much later inventions. This theory was repeated so many times that a lot of people assume this to be true. It gets quoted again and again. In reality this is as false as Trump's claim of re-election victory. The oldest domesticated horse bones in India were found in Rajasthan around 4500 BCE. However the white researchers have not bothered at all to revise any of their theories despite new evidence. There are over 15 different instances of domesticated horse bones ranging from 2500 BCE to 3000 BCE have been found. Please read Srikant Talegari's paper on the topic.
Linguistic evidence:
This is actually pretty lame evidence to begin with and can very easily be repudiated. Early white christian researchers believed that Aryans invaded India killing native people (to justify why British rule of India) and they claimed these Aryans came from Russia 3000 BCE. How did they arrive at this conclusion ? Linguistics shows that all 12 branches of Indo-European languages were together sometime around 3000 BCE. It was not clear when, but the "south russia" claim is completely random and unsubstantiated. During these times Avesta, the holy book of Zorostrasians was the only non Hindu text that would talk about Vedic culture but it was orally transmitted and hence had not physical artifacts. Much much later, Mittani treaty was discovered in Syria which was around 1500 BCE old which clearly indentified itself as Indo-Iranian. So many western scholars took this as contemporary of Rigveda without analyzing both books in details.
Rigveda which has 10 books is generally classified as core and non-core. It is unanimous opinion that core is much older than non-core. It turns out Mittani shares a lot of words and linguistic traits with the non-core where as nearly none with the old core. Mittani's own languages is a "residue" of old vedic languages which they picked up centuries earlier. Hence some of the researchers think that Rigveda predates Mittani by significant amount of time.
Note: I am not emotionally involved in any of the dates, other that pure academic curiosity I think it is irrelevant if it s 3900 years old or 5000 years old. The only point I am trying to make is that Rigveda dating is not a "settled" matter as some claim and we will see more interesting research in future.
