Were they charting the world thousands of years ago at Nazca? ls this the answer? The Nazca lines extended out over the earth look like a modern day map or globe. Angkor Wat is the key.

And do any converge at the other end of the earth at a very ancient sacred temple? Case Closed. l need a new mic. Don't sit on your headset/mic.
