It was Thoth, the Atlantean Priest king who was said to have constructed them. He says in the Emerald Tablets of Thoth, “I have structured these stones with earths natural forces to withstand the test of time.” Through super advanced ancient technology, vibration, sound. They were portals, star gates, spiritual ascentian chambers, giant power plants of energy. There are 24 located throughout the earth, all with the same structurally design at the base, aligned similarly, meaning it was the same architect. Thoth. Have heard they were built about 40,000 years ago or something. So fascinating. The recent align podcast with Aaron Alexander and Robert Edward Grant talk some good wisdom about it, Robert is super advanced with this stuff.
