The ancient Egyptians were a highly advanced civilization, and it has been suggested that they may have had help from ancient astronauts. One theory is that the ancient Egyptians used drones to build the pyramids. The theory goes that the Egyptians could not have built the pyramids without the help of sophisticated machinery, and that the only way they could have acquired this technology is if it was given to them by aliens. There is some evidence to support this theory, such as the fact that the pyramids are perfectly symmetrical, which would be difficult to achieve without the use of advanced technology. Additionally, there are ancient hieroglyphs that depict what appear to be flying machines. However, there is no conclusive evidence that the ancient Egyptians used drones or any other advanced technology, and many scholars believe that the pyramids were built using more primitive methods.
