Why this site. Teotihuacan was one of the largest cities on Earth in its time and left behind no name of any ruler, no royal tomb securely identified, not even its own name for itself. Teotihuacan is what the Aztecs called it centuries later. Its geometry test comes in above chance without clearing significance, and the control ratio scored 1.22 against phi's 1.38, close enough that we are not claiming anything. The Avenue of the Dead is genuinely off true north by about 15.5 degrees, deliberately, and why remains open.
