Right, as if no real person believes that slaves built the pyramids.

Just chiming in with another golf clap, well played sir.
In fact Herodotus only mentions the number of workers on the pyramids, he did not identify them as either Jews or slaves.
I’m not sure about tempering copper, but It is evident that the level of competance at the time was individually, and collectively very high. While we can easily imagine engraving a stone with a harder object, we mustn’t forget all the other tools and accessories. Very good quality ropes, pullies (rolls) made without lathes, mesuring techniques, even the planning itself must have been daunting. (no paper, no post its, no cell phones) must have been sort of difficult to leave a note for the foreman.
They had lathes.
It should be noted that by modern standards, wrought iron is a fairly soft metal. Yes, harder than ordinary copper, but that’s not saying much.
Actually, I think there have been found some examples of screw-ups - the example I recall was an obelisk that was broken during cutting out at the quarry and was left there, still joined to the bedrock.
