Where are the horses that the Aryans rode into India, hmm?
Because they never went to India, that’s why.
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.
