The Nazi racial theories were adopted by 'science' which then set about "proving" them. They even corrupted archaeology in their attempts to create a scientific basis for these theories.
I know I sound rude, but it's okay to stop talking when you don't know what you are talking about, and it is (painfully) evident that you've got no idea.
Nazi racial theories were built upon Darwinian theories of evolution. There was a whole branch of pseudoscience dedicated to this sort of thing, beginning in the 1860s/1870s, which also fed into the eugenics movement and into places like Australia.
The Nazis married these ideas with their own myths about the German fatherland, with an added twist which suggested that the Jews were the natural enemy of the Aryan.
