Hitler didn't think up the "Aryan race" myth, it was around way before him. It was created by British scholars to try and justify Indian colonialism. It latched on with the Theosophical community, amongst others.
I'm also pretty sure that the Persians were not thinking of a race of blonde-haired, blue-eyed Nordic superhumans who mysteriously colonized and disappeared from the Middle East, when they used "Aryan."
