Great Mystery of the Past: The Great Pyramid of Giza
Many theories have been proposed regarding the Great Pyramid of Giza and its construction techniques. The Pyramid of Giza (also known as the Pyramid of Khufu or the Pyramid of Cheops) is the oldest and largest of the three pyramids in the Giza pyramid complex bordering present-day Giza in Greater Cairo, Egypt. It is the oldest of the Seven Wonders of the Ancient World, and the only one to remain largely intact. Was there once a time where there were people or something more advanced and intelligent then we are today? The Great Pyramid of Giza is one good example of a lost great knowledge.
