By definition, any person born in America is a Native American. The Aboriginals however, AKA American Indians, were here first.

Of all the Native Americans in the U.S. the Aboriginals have been here the longest.

Indian-Gaming has been a large source of funding for the educational system of the Aboriginal American population.

It is true that Aboriginal Americans are also Native Americans, but it is also true that every other person born here is a Native American as well.
