>Some end up on Easter Island, and build giants to mock their enemies
Genetics have implied the original settlers were pacific islanders rather than injuns. Sure enough it fits to the t pacific islanders/war escapees being master sailors.
>white explorers make landfall on many of the islands and witness whites
I lost trace there, pacific islanders were white, the race war in the crescent/caucasus area had the dark skinned ones run away and become white all of the sudden, i don't get it, doesn't link the genetics done in Easter Island and your story
>all the whites died off from disease, presumably spread by the explorers
Everyone and their dogs died of disease, that's true and same with south america elites being known to be clear eyed and light-haired, along with some injuns having those traits but with their red skin.
I can easily believe the race war and migration of highly skilled groups, because there's plenty of evidence of both, but the pearly white thing always seems odd to me if a bit wewuz. Those guys are most probably not the same stock of white as the one we know, and many do describe them by eyes and hair but with different skin, nor pink or white but reddish (sunburn or a different one).
By description they might as well be also light-haired koryaks in the case of the native american tales, grey aliens in the case of the olmecs and toltecs and some sort of heavily sunburned vikings in the case of the incans. Fucking injuns and their lack of subject description skills.
Very well put, also worth adding around the context of the discussion (30,000 or 12,000 years) that Qing is the dude who invaded most states and killed tons of men, banging all the locals with what can be considered han troops, around 2000 years ago to accomplish some sort of pax qink
that ended up with the guy never sleeping at ease due to the amount of plots against him.
A massive mongreling scheme that contrasts with the Shanghai phenomenon of various different races "originating" from a small area in the northeast of said China territory.
