Properties of elements are very well known. Elemental copper cannot be hardened beyond a specific point. It must be in alloy in order to have different properties.

People who claim the ancients were more knowledgeable than we just don't know any better. I used to hang out with "New Age" people. Their knowledge of physics or chemistry was non-existent. They also had no idea what the current state of the art had achieved. They had delightful imaginations, and were frightfully gullible.

And so its child’s play for modern sculptors to carve Ramses Statues and the ornate columns found at Karnak as well as the granite boxes of the Serapeum of Saqqara using just the tools found in the archaeological record? Which set of stone and copper tools achieve a consistent 4 mm corner radius over and over again?

Building the complex at Giza to scale takes merely a few months or so for modern engineers?

So building the Giza Complex based on the Golden Mean, Fibonacci numbers, and the Coma of Pythagoras was just a fortuitous accident? As was the alignment with the stars of Cygnus?

I think you have vastly underestimated what the ancients actually achieved - likely based on casual glances. The more those few artifacts are studied, the more complex they become to actually build or carve; the more unlikely that the assumed tools and methods used, as further assumed by archaeologists, become.

You also understand that anything like advanced knowledge of physics and chemistry found by Egyptologists (Hawass & Lehrer) would be immediately suppressed and hidden, if not destroyed, because it would contradict the current lucrative meme?
