By definition “indigenous” people never got off their ass and went anywhere, let alone sailed to any new lands.
People who stole the land from the previous “indigenous” people.
Actually the “indigenous” ancestors colonized the land. The all migrated from somewhere. I don’t think there’s evidence of an independent rise of human creatures all over the planet. We have no idea who murdered whom in prehistoric times. All we have is tradition and folk tales by the conquerors. History is written by the victors they say.
