Sorry to push the issue, but that is is the elephant in the room. Until it's solved, AA proponents will insist and quite rightly so that PP is far more ancient than the Inca.
The stones say so, the technology says so, and the folkore (or lack of) says so.
These represent serious discrepancies with mainstream findings.
So we still have evidence of alien construction; not indians.
Yeah, if only those people would stop telling us about their origins and start telling us about their origins.
There are ethnic groups in the Americas who've only existed for well less than 1000 who can't speak accurately about their origins. Others in other parts of the world we wouldn't know about if somebody hadn't written about it and still others we've had to piece together. You're expecting way too much.
