The Great Pyramid is just too precise for me to believe that ancient groups of peoples could have built it. Either people not from earth built it or God did it. Architectural, mathematical, geometrical, astrological... it lines up in near perfection with all of the above. Todays top engineers say they could not build something that accurate in the above using todays technology. They all chalk it up as an unexplained mystery. Were the Egyptians far more advanced than todays civilization?
