Energy weapons could be feasible, given the existence of nuclear glass and the Vimanas.

Healing chambers I’m not sure about. That explanation comes from anecdotal “past lives” stories and channeling, right?

Beacons? Maybe.

Multiple uses for pyramids sounds plausible.

Regardless, I think everyone can at least agree that an intelligence more advanced than our own has existed thousands of years before the industrial revolution.

The hows and whys may as well not even matter when the accomplishment speaks for itself. We can’t replicate the great pyramid with modern machines.

I suppose the biggest question is to ask what mind produced the original idea for the great pyramid. Was it human or non-human in origin? Being that there are no records of how such structures were built, it then falls into:

a) lost knowledge or b) knowledge we never had.

The Coral Castle does suggest “lost” (human) knowledge, but the scale of the pyramids (and the interior) suggest something beyond human capability.

Have you thought about tying in the idea of Atlantis into the construction of pyramids? Or the purpose of them being to establish a Christ consciousness grid?

Fringe ideas for sure, but there has to be an explanation somewhere that makes perfect sense. Although I’m not crazy about having to believe in ley lines and grids. The rabbit hole just keeps getting deeper and weirder the more this subject is explored.
