How did the Nazi Aryans come from? What about the Indian Aryans? Can they have the same ancestor?

It is an ancient tribe in Caucasus and Central Asia, which uses Indo-European language family. Aryans were originally an ancient people on the grassland in the southern Urals Mountains of Russia, from which Aryans migrated to Europe and Asia in several branches. Among them, an Aryan settled in the plain between the Amu Darya and Syr Darya rivers in Central Asia. This Aryan is called the Indian Iranian. About14th century BC, a branch of the Indo-Iranian went south into the South Asian subcontinent and was called the Indian Aryan, which was called the Aryan in ancient Indian literature. Another Indian Iranian entered Iran, called Iran-Aryan. In Iran, they merged with ancient people to form later Persians, Medes, Skettians and so on. In India, they expelled the Dravidians to the south, created the Vedic culture, established the caste system and brought the Indian Aryan language to India. After Hitler came to power, the German Nazis changed the original definition of "Aryan" and used this word to refer to "noble purebred", proclaiming that the blond Germans were the model of Aryan. In fact, classifying Germans as Aryans was just a propaganda method with no scientific basis for the Nazis. The so-called "the most perfect and purest Aryan image" by the Nazis is actually a shape that can only be formed after long-term evolutionary screening in northern Europe, northern Russia and other areas near the Arctic Circle, which is far from the birthplace of Aryans that historians and biologists have long proved. Aryans, as nomads, may have a considerable pedigree in Germany, but Germany, a world-class scientific and technological power, is indeed a "crazy era" for the Aryans to be branded with blond hair and blue eyes.
