Imagine finding an ancient artifact so strange that even experts can't agree on what it was used for! That’s the Sabu Disc, a mysterious 5,000-year-old object discovered in an Egyptian tomb. Made of fragile metaschist stone, it looks like a modern machine part with curved blades and a precise circular shape—something you wouldn’t expect from an ancient civilization. Some believe it was a ritual object, while others think it might have had an advanced practical purpose, like a spinning tool or even a lost technology! The mystery deepens because nothing else quite like it has ever been found.
