DNA shows that others were here before todays third or fourth Americans. Todays natives or those with a little native blood are not related to the real first Americans. They also got off a boat or walked here like everyone else who lives here. They moved here just like the rest of us. What did they provide for us anyways. It is quite the opposite. In thousands of years what did they accomplish? Others still have to take care of their feces for them as they can not do this on their own.
