Comparing achievements using the same old world timeline for the Americas is the best indicator for sub 70 IQ retards, the Americas were the last continent to be populated, not to mention it was populated by a bottleneck of a few hundred people while the old world obviously always had much more people and land mass faciliting multiple civilizations interacting with on another, even considering all of this, Teotihuacan was contemporary to Rome, Romejeets were unironic brown streetshitters with intestinal parasites that loved killing each other with machetes in an arena like retards, I don't even have to mention nordcucks from this era since they were literal mudhut dwelling apes, amerindians were playing on hard mode and still managed to mog europeans by creating civilization by themselves
