In any case, the original Giza-area pyramids were absolutely spectacular, IMO. We moderns see basically thousands-year old rubble and make judgements upon all that.
Au contraire, those suckers were absolutely unreal for the time. Truth. Facts & reality.
they were actually constructed as defence against aliens, ironically enough.
It’s the same principle as modern drivers with 5 billion lumen LED headlights aimed directly into your rear mirror, and was particularly effective since Greys have such big sensitive eyes.
