The first people to break into the Great Pyramid found nothing. They tunneled in because they could not find the actual entrance and were looking for gold on the orders of the Calif. Very disappointed, they were on finding the structure empty except for a stone sarcophagus. No gold, no jewels, no inscriptions, no robots.
Yes, that’s one account, that they didn’t find anything. There are other traditions, claiming they found quite a few weird things. That’s why I brought it up.
