The Great Pyramid of Egypt is a marvel of engineering and design. It is 149.4 meters high and made up of about 2.6 million stones, some of which weigh up to 70 tons. The pyramid is perfectly located in the middle of the five continents and has corridors that align with the North Pole star and the star Sirius. Plants grown inside the pyramid grow larger than those grown outside, and the king's chamber has a mathematical relationship with the ocean's rise. All of these facts suggest that the pyramid was not built by accident but by design, using knowledge that the Egyptians had available to them.
