 So whoever built a pyramid before the Egyptians came, they had technology that was more advanced than we are privy to today. And it could be some kind of technology based on frequencies, like there's one theory that they were using frequencies in order to levitate things. That's a possibility. Or anti-gravity using some kind of frequency or some kind of a, some kind of energy which is highly possible, right? But yeah, there's, I think back then they were more in tune with, I guess these, I would say geometry, definitely. Because geometry is also frequency, right? Because if you try and go, they have angles and each angle is a frequency, right? And like if you have a cube, you have 90 degrees in each corner. So geometry actually is in itself actually frequency. So they understood that a lot more than we do now in the way that they build structures, in the way that they create even music is very different from how we build things and create music these days. Yeah, interesting.
