The guy who put up the money for this called himself R.C. Christian. That has been since been determined to be a false name. Additionally, how does anyone know if he was the one really responsible? He may have been a front man working for someone else.
The Guidestones were put up in the late 1970s. The threat of nuclear war was on everyone’s minds. One of the things the stones say is to keep the world’s population under a half billion. No one is saying we should kill six and a half billion people. Well, about five and a half billion at the time the stones were laid. This was probably erected for post nuclear war survivors. The world’s population would surely be less than a half billion. It was a warning never to let it get this high again.
I don’t believe this was put up to help bring about the New World Order. It was to guide what’s left of humanity after WW III.
