The pyramids have always been more than what we know today. These were not Tombs and temples but something far more advanced than we are today.
Our modern science still hasn't figured it out yet for many reasons. But one of them is the lack of understanding of Consciousness. These civilizations mastered the knowledge of consciousness while we are still looking for a book definition.
These pyramids were made with extreme precision. Not only the outside but also the Inner chambers. In ancient times, these were used as multipurpose buildings. They were healing centers that were connected to the universal consciousness. It allowed people to heal their body, mind, and Spirit complex. They used portals, and they were connected to different stars.
