I wouldn't discount the ley line theory, but I can't 100% support it either. It's possible that there's something scientific to it even though it can't be measured by publicly available scientific instruments.
Scalar Energy isn't accepted by mainstream science, but from my research seems very legit and links to the work of Tesla. The Cabal has access to a lot of knowledge and science that we don't know about. Entire histories are stored within the Vatican and kept from the public.
I believe the Egyptian pyramids were part of a larger planetary energy involving ley lines (obviously can't prove).
With all the secret work being done with scalar energy + cabal's secret knowledge,this ley line theory is entirely plausible to me.
It's hard to give sauce for advanced and classified technologies. I don't think anyone can conclusively prove or disprove ley lines with publicly available info.
