The idea was to have a quarry where stone was broken into reasonable sizes, nothing much bigger than a volleyball more or less, hauled to the build site in wagons by elephants or whatever, dumped into formers, and then whatever mortar they were using poured into the formers to fill out the space. That’s how they got the unreal tight fits. I mean if you think about it, trying to carve blocks at the quarry would waste 2/3 of the material if it could be done at all which is doubtful. That would be if you only needed five or ten such stones; no way in hell is anybody going to produce millions of perfectly carved stones that way.
So do you think the Great Pyramids are older than the mainstream says they are?
