There are plenty of theories out there regarding as to why the ancient Egyptian civilization had access to these advanced technologies in the past. Many believe that they were only able to build the ancient structures such as the Great Pyramid only thanks to the technology they received from the aliens all along.
This recent discovery might actually clear up a lot of fog regarding it, as many believe that the ancient pyramids of Egypt and specifically Giza were meant to be doors to the stars all along. This 4,600-year-old papyrus scrolls that were discovered near the Great Pyramid tell us the story of Merer and how he worked at the Great Pyramid, to begin with, in ancient times, around 2560 BC
He talks about how he took 2,3 million granite stones and transported them from the Gulf of Suez all the way to Giza on a ship. This is a 13-17-kilometer trip that they needed to undertake constantly, as they couldn’t fill the boat up with all 2,3 million stones in one go. He talks about how he needed a 200-man crew from Tura or Maaasara in order to get the work done on time and about how he was working directly under the half-brother of Khufu, Ankhhaef.
