Quite remarkable how we are supposed to accept the 2.5 ton solid granite blocks used to construct the pyramids were perfectly carved using basic copper hand tools with no electricity and the accuracy of the whole pyramid would have been difficult to achieve today using modern lasers. Then they tunnelled through solid granite to make up to 150' long tunnels with less than 1/50th of an inch deviation along the whole tunnel.
People have no idea what accuracy and precision mean. As a finish carpenter I've had to trim residential construction that was literally more than 3 inches out of square over sixteen feet. While that makes my work difficult, that's why I get the big bucks.
