Imagine we wanted to make an exact copy of the pyramids in Egypt, the great pyramid specifically.
Never mind building them without machines. Do you think mankind, not just the current residents of Egypt, but do you think in this world there exists the technical know how and political will to even be able to do it?
This perspective prevents building, because it specifies artifice over nature.
Technic/techno/tekhnē - "art" tempts one to ignore natural knowledge. Look into how Schauberger was being smeared as "water wizard" by the scientific community, because he told them that water cannot be measured in a lab, only felt within nature.
If one discerns to reside (life) within current (inception towards death); then one can shape anything within everything provided.
Build.
There's no way we can accomplish this today. 2 and half millions stones placed perfectly line up with astrological alightment and the fibonacci sequence. Can't even fit a single sheet of paper in between the stones with no mortar.
The eight sides from above that's only revealed on the solstices is pure genius beyond man's capabilities.
