The pyramids of Egypt are fascinating mind puzzles. The claim that Egypt had technology or knowledge that would be advanced even by modern standards is interesting and curious. The theory seems to rely on ideas that the pyramids and other Egyptian objects show signs of manufacture with advanced equipment and engineering. But, not being an engineering specialist, this is not clear to me. I know Egypt had the workforce at Giza to accomplish the pyramids in their scale, but the design, intent, engineering of the pyramids is unclear to me in its nature. Adding to this difficulty is the fact that those who propose theories of ancient astronauts, supernatural technology or other advanced knowledge or equipment rarely seem to have their work published in serious publications. I understand that the scientific establishment is very very skeptical of such theories, but it seems nonetheless that there should still be occasional publications on this among the many journals available in the last 30 years or so if the proposition of ancient advanced engineering technology were true and real. With that in mind I wish to ask: 1. What is the best evidence of such advanced technology in Egypt? 2. Can you recommend scholarly articles within a few pages that are persuasive on the topic, the kind that you could actually use in a real research paper? 3. What is the best evidence, if any, that the pyramid was used as something other than a tomb? 4. Do you think potential excavations could reveal new amazing finds like we had with the Rosetta stones and pyramid texts, or like Edgar Cayce imagined/claimed with the Hall of Records?
