People who claim the ancients were more knowledgeable than we
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?
How many people worked on building those statues and pyramids, and how long did they work? Serving a lifetime for a "god" even to partially complete something that was passed on to the son would be a source of dedicated labor.
I never said they didn't have an understanding of math. I never did say that they weren't patient and tenacious workers. I merely said that they did not do anything that we cannot do right now. The cathedrals of Europe prove that post-ancient people can make some spectacular things. On the other hand, we aren't working for gods. We work for pay; and, nobody wants to pay for immense works of art these days. We have no god-kings who make such demands.
We do have hobbyists who spend a lifetime making incredible model railroads or ships. We even have people who work with hand tools making tiny gasoline engines that actually run. If they were gathered together on a project of some sort, imagine what they could do. The point is, we just don't need to make Egyptian-like stuff anymore. The god-kings no longer rule. Nobody else wants a tomb like those.
