The proper term should be First Peoples, or First People

I find that "Indian" works as well today as it did for the first 600 years in the New World.

"First Peoples" is just as PC as "Native Americans."

I never really considered “First Peoples” to be PC, because their ancestors were the first humans to reside in the Americas.

Ironically, I have heard the members of various tribes refer to themselves as “Indians,” which is what I call them.
Or I call them Navajos, Chumash, Nez Perce, Sioux, Penobscots, Seminoles, Pequots, or whatever their respective tribes are named.
