"you should also consider that mankind must be devolving rather than evolving."
" "I personally think that humans were quite advanced at one time in history, but about three or four thousand years ago we were set back a bit (think "big flood")."
OK, I will think big flood. The climate and atmosphere would have changed greatly. If there was a higher percentage of oxygen in the air, and the air pressure was greater, everything would have been bigger. Plants and animals, and humans. And we have found XL giant fossils. Add the extra strength per pound multiplied by the added size of the humans, and the pyramid would have been easier to build as far as moving huge stones around.
As far as the precision of the stones, and the angles of the various features pointing to stars and cities, the rich atmosphere would have let humans live longer, and be more intelligent. They would have learned more for both reasons.
Lots of info here...
