Ancient Civilizations

Still a good listen.

Most interesting part is the he confirms the void above the current opening of the Pyramid used as the main door is real. This void contains a long hallway and who knows what else. I saw it posted around in here earlier but didn't know if it was substantial at all.

Guess it is. The guy says that a big issue is that the entrance used today was never meant to be an entrance at all and it makes accessing such a space very complicated. So they haven't figured it out yet.
