Giza the ancient's prime meridian

Mind blowing to think of how previous civilizations drew a map where the line of zero longitude, instead of running through the Greenwich Observatory in London, ran through the desert, just adjacent Cairo. 

The Great Pyramid (the Pyramid of Khufu, or Cheops in Greek) at Gizeh, Egypt,

demonstrates the remarkable character of its placement on the face of the Earth.

The Pyramid lies in the center of gravity of the continents. It also lies in the exact center

of all the land area of the world, dividing the earth's land mass into approximately equal quarters.

The north-south axis (31 degrees east of Greenwich) is the longest land meridian, and the east-west axis (30 degrees north) is the longest land parallel on the globe. There is obviously only one place that these longest land-lines of the terrestrial earth can cross, and it is at the Great Pyramid! It means that Egypt, the Great Pyramid at Giza to be precise, lay at the centre of the last world. Incredible.
