It seems to me that indigenous means that you claim your culture originated on the land... my ancestors came from Ireland in the 1930. I don’t behave or speak like those in Ireland do — I’m indigenous to Indiana.
Besides, the original Clovis culture died when North America was hit by a comet 12,900 years ago... Everyone here is an immigrant.
check that... my ancestors came in 1830, not 1930...
In the meantime the Sa'ami continued to exist in Europe, and I'm sure if they could have gotten here they would have ~ and probably did right down to about 8500 BC when there was another serious rise in the sea level.
For all we know they may have continued to come in from Asia ~
