>>39842652We have mummies with red hair in south america, that's different from mummies being "white". AFAIK, There are some indigenous groups in South America that have red and blond hair has mutations even though there's no genetic link between them and euros
That being said, South America =/= Meaoamerica, and i'm less informed on South American shit then Mesoamerican shit.
>we don't know who built the pyramidsJust because YOU don't know shit about Mesoamerican history and don't understand it's different cultures or eras or the progression of them doesn't mean we all do.
Pic fucking related. We have sites clearly belonging to specific cultural groups such as the Maya dating back to like 2000BC and you can see the gradual development of stuff like monumental archtecture, class systems, etc at sites over time; sites which have burials that have people which, guess what, we've tested genetically; and we can also see the gradual spread of specific archtectural and art motifs, the gradual change in iconography, etc across various towns and cities over time, such as evolution of rain gods from the intial Olmec ones to Maya, Aztec, Zapotec, etc ones:

In general we have a pretty fair amount of specific political records of stuff like this for dozens of Maya cities, such as births or deaths of memebers of royal families, alliances, marriages, wars, construction projects as I just noted, etc; while for the Aztec we have more detailed historical accounts down to specific statements down to specxific political officials.
You might as well be saying that some random site in greece or china might have been made by spics even though the sites in question totally fit within the broader Mediterranean and chinese archreological framework and it's cultural trends.
