How can Egyptologists still perpetuates the pseudoscientific belief that copper tools had been used by the ancient Egyptians to carve granite?
Simply put from a chemical point of view, it is highly inefficient. A honest scientist must agree that copper’s hardness is lower than granite on the Mohs scale, there’s no debate on that claim. And for that reason working with copper would be impossible.
Then how can this dogma still prevail in modern Egyptology?
Some people will claim that no archeological evidences for highly advanced machining has been found but again that’s utterly wrong. In fact an enormous amount of saw and drill marks is being found. What Christopher Dunn found was enough to prove the advanced tools the ancient Egyptians used for their times.
How can Egyptologist pretends to do correctly their work if they dismiss primordial informations?
The video below will show you first hand evidence.
Instead, rather than admitting the obvious incoherence, fanciful theories have been propagated to keep intact a dogma that profiled these people without any other tools. In an effort of always bringing down ancient civilisations compared to our modern ones. As if acknowledging these obvious problems in the copper tools theory was finally breaking down an old paradigm. The copper tool theory should be long gone by now.
