How close to true north could you pinpoint a line by only what you know about the path of the sun? That is how the uniformitarian biblephobes would have us believe the Great Pyramid was built aligned to true north with a .05% accuracy, which actually was done by the rate of precession of the earth’s polar axis (72 years/degree) with the stars as the backdrop, a measuring sphere, a 3D clock, like a GPS system by what could be called astro-geometry (see Page at right Great Pyramid for Navigation).
