If they never went to India, why do they have such similar, and rather unusual burial customs between India and Russia? And why are there similarities in language between Russian and Indian languages? The original reason for the proposed existence of Aryans and their travels is due to language similarities between European, Asian, and Indian languages, not any particular archeological sites.
Thirty or so kilometres off the southern coast of India lie drowned cities made of stone, some with pyramids.
These cities would have been above sea level 18,000 years ago. The Aryans didn’t invade India; the movement of people northerly as the sea levels rose has been corroborated genetically.
Those peoples from southern India were ver dark skinned, and the prejudice in believing they had anything to do with spreading Indo-European languages is strong. I suspect Sanskrit is quite a bit older than most historians would acknowledge and dates from before the end of the Ice Age.
