Reported UFO Shapes over the years. Some are alien/Nephilim made, Earth Gov made and some are not solid but are spirits that shape shift into the image of a UFO. If you've ever seen one that can't hold it's shape lol I have!
28 Large Stone Boxes in the underground Serapeum at Saqqara are made of granite, presumably brought from Aswan which is 500 miles away. The lid was cut from the same block as the box itself, and the two combined weigh more than 80 tons
