It seems to be based on a conspiracy theory called "the great circle of ancient sites". It claims that a lot of ancient sites are aligned on a great circle on earth, close to the equator, and that is a sign of all these ancient civilizations secretly communicating and being more advanced than we thought.
However, it boils down to simple statistics abuse, as a lot of ancient sites exist and you can draw various great circles through many of them.
You could do the same thing if you'd randomly scatter dots around a sphere and after the drawing of a circle assign significance to all dots on the line.
Looking forward to see how this game interpretes it
