It was very common for archaic people to call themselves Humans. Many aboriginal peoples had a name for themselves that simply meant “people” or “humans.” Adam means human or more specifically, red human. The Ainu were an aboriginal people and the word “Ainu” (Annu) means human. It appears that the earliest populations self-identified as human, as distinct from other animals. Even the names given by paleoanthropologists to archaic populations work like this. For example. “Sahelanthropus tchadensis” simply means the humans of the Sahel and Lake Chad basin.
The metal working caste of Anatolia (Turkey) called themselves the Nes (NS) which means Human. They called their language Nesli. In Serbian nas means us, naš means our, naši means our people, naški means our language.
