Why did the Aryans come to India

Aryans came to India, with the British, in the 19th century. Many British Indologists and a German one, created the Aryan invasion theory, by giving racist meaning to a Sanskrit word 'arya' which meant nobleman, at a time when race was used to justify colonialism. So, Aryans entered India, not by land, not by sea, nor did they land from the sky. They came through the textbook route.
