This documentary-style video explores the mysteries of the Great Pyramid of Giza. It begins with a dramatic aerial view and poses the central question: how was such a monumental structure built 4,500 years ago without cranes, concrete, or computers? The video dives into engineering theories, including the use of sleds on wet sand, spiral ramps, and skilled labor—not slaves. Viewers are taken through the step-by-step construction process, from site planning and stone transport to worker life and precise assembly. The film also examines the pyramid’s symbolic role as a bridge to the afterlife, aligned with stars like Sirius and Orion’s Belt. Ten astonishing facts are revealed, including the polished limestone casing, a mysterious hidden chamber, and the discovery of a 43-meter solar boat. Common myths—like alien involvement and "power plant" theories—are debunked with science and humor.
