Pyramids of Ghiza - the alignment being within (apparently) 3/60th's of a degree within True North. Here's an idea about that (and the age of the Pyramids): Given that the precision of the Pyramids is soooo remarkable, I wonder if perhaps, when they were built, they were in fact even more precisely aligned - maybe even exactly perfectly aligned. If this was the case, how long ago would they have to have been built for the current offset (3/60th's of a degree) to have been produced by the movement of the techtonic plates??? anyone?
