5. Pyramid of Giza
The Great Pyramid of Giza is the biggest and the oldest one among the three pyramids forming the Giza Pyramid Complex. The tomb of Khufu, the Fourth Dynasty Egyptian pharaoh, rests in this pyramid. Researchers believe it to have been built over a period of 10 to 20 years and completed by around 2560 BC.
Before the development of modern-day skyscrapers, The Great Pyramid of Giza had been considered to be the tallest structure in the world and has continued to baffle egyptologists and engineers with its methods of construction during those limited times.
Even though we have proof that UFOs exist now, however, we still don’t know the hacks that went into play to create the legendary masterpieces that still puzzle us up until today. But can the mystery of man-made objects come close to the mystery of the mother nature?
