Maybe the Indians were the madeup stuff, sure some. I'm thinking Phonesian society was possibly there and the marble was real buildings they left and then the US blew the shit up so they could push the fake we discovered america when in fact the Chinese and Phonesians and the vikings had already discovered the US the american indians and a lot of other shit and they couldn't cover it up anymore so the world fair to protect our made up history was concocted to push the oldest narrative there is. Hell they covered up the giants so why not this and everything else. It's all bullshit, we just realize it now unlike the average NPC out there that believes everything they are spoon fed.
