Anything the ancients have done we could also do. Name one artifact that we couldn’t produce.
Let me find the source videos again and I will get them to you, there are several on this exact topic. But all my bookmarks are in the old computer. There are indeed some examples of stone work so fine and exact that they are deemed by the stone experts it would be impossible for us to reproduce even now with power tools. The only thing close would be lasers.
I don't think this is true. I've watched many of these documentaries on ancient civilizations, and modern engineers say they can't duplicate many of the things done back then. Our largest construction vehicles couldn't lift and install the massive stones in ancient structures, and couldn't be fitted with the same precision. Many ancient carvings appear to have been cut with finer precision than modern computer-driven lasers, impossible to do by hand-carving to be symmetrical (left and right facial images for instance).
