Well yeah, the groups of people that presumably traveled across an ice bridge from Asia typically referred to as The "Native Americans" if they somehow did overpower European settlers then it would've been their right to tell them to return to Europe.

The Natives Americans were Native to the America contintent but were a tribe, not a Nation, The Nation of The United States is Descended primarily from Anglo, and Germanic individuals, so it is fair to say That there were Tribes on The American Contintent but The Nation of The United States is Anglo-Saxon, or European.

Also supposedly Nordic Vikings went to The America's well before Spanish exploration.

So who knows.
