The Aryans came into India from the North-West around 2000 BC. Their homeland was somewhere in that direction but they weren't natives of India. The basic Nazi idea was rooted in a linguistic observation still accepted today, that many existing languages have a common root that is referred to as "Proto-Indo-European" (https://en.wikipedia.org/wiki/Proto-Indo-European_language) because no name survives for that hypothetical-but-believed-to-exist language or the people who spoke it. Hitler referred to them as Aryans because it's a plausible thing they might have called themselves, since several of their terminal offshoots in different locations called themselves variants of that.
