Indigenousness is Wobbly
The Maori and Aboriginal peoples claim New Zealand and Australia's land as theirs. Probably many native Americans in the USA do the same for North America. 'Indigenous Peoples' Conferences" have taken place in South Sea Islands. But many anthropologists take them to task. Can you really "own" land because you were there before another race? Whether or not those claiming to be 'original' races is open to question. An example I once read about was that a race of humans inhabited Japan long before the Japanese 'race': the Ainu people. And it's said that a race different from the Maoris inhabited New Zealand long before the Maoris.
