The height of the Great Pyramid in Egypt is 149.4 meters and the distance between the earth and the sun is 149.4 million kilometers and the direction of its door towards the polar star. The angles of the pyramid are also pointing to the four original directions.
Al-Ahram was only 20 years old.
The number of stones from which the Great Pyramid was built is 2.3 million.
The building of the pyramids dates back to the fourth family that ruled Egypt from 4000 BC.
