As I said, your assuming that it has to be like todays tech and devices. It would be rediculous to say that there was machines and computers like today everywhere. Yes we would definitely find it. We should have found something as its not small and the works are wide spread counting other signatures in blocks ect.
It may have been something similar to a modern machine but made of basic components of stone and copper. Or as some have said a copper cutter embossed with diamonds or some or very hard stone. Maybe aqua power. Most of the components will have been reused, melted down by later people.
Or it could be something completely outside the box like stone weakening or softening. Then hardly any tools or machines are needed. Am ordinary spatula or shovel can dig out or shape the stone. More about changing the material than needing powerful tools to cut such hard material. To me this makes the most sense.
The point is not to assume any particular tech or device was used and especially that it worked like modern tech. Their modern tech may have been in a completely different ball park. Something more natural perhaps and toying with the structures and makup of rocks themselves perhaps.
But I am not saying this is a fact. Only that we should not assume that over 100s of thousands of years and especially say in the last 12 to 14,000 years that knowledge and tech did not peak several times and was los. Then people began again. Some continue and others disappear. All sorts of alternative knowledge could have been around and lost.
THis is the exact testimony the peoples of the later cultures were saying. That their ancestors or people that came before them had advanced knowledge and it was lost. That they found their works and inherited them. Don't you believe them.
An absolute load of bunk and bull.
I don't give a flying fig if the tech is the same as it looks now or if it looks totally different but functions the same way or looks totally different and functions a totally different way, the bottom line is that when you and others like you who claim that the ancients had advanced tech greater than anything we say they had, you present NOTHING of said tech existing. You always go with just saying "Oh, they created these things! That's evidence enough!", but when pushed by any skeptic to present evidence for the tech that created the so-called evidence, you suddenly go deaf, blind and dumb.
I don't give a care about groups who said that their ancestors had advanced knowledge and lost it, because it's just a 'just-so' story to explain something they couldn't explain back then. And it's such a brilliant example of hypocrisy from you, especially since you've shown that you ignore the traditional workmanship of others who actually know their craft and just go "But they couldn't do it!"
Why couldn't they do it? Simple: because your entire argument is nothing more than an argument from incredulity. You can't personally imagine how it could be done, therefore no-one knows how it could be done, so you have to use such extraordinary claims to fill in the gaps in your own knowledge and ignore what other more intelligent people, are telling you time and again.
Again: you want to make the claim that the ancients had advanced technology? Then present the evidence of the technology existing; either the technology itself or actual contemporary artistic depictions of said technology. Because the fact that the latter fails to exist is suspicious, but coupled with the fact that in over a century of exploration and discovery in Egypt and other places linked to so-called 'advanced ancient cultures', we have not found a single shred of actual advanced tech existing, it's pretty damning that your claims are bunk.
Graham Hancock must be someone you look up to, I bet.
