No there are not. Have you ever seen a dry-stone wall? Here's an example:
Walls like this are found all over the world. Some are thousands of years old, some are centuries old, and some were just built last year. This isn't high-technology, this is just the patient use the human ability to organize their memories (of shapes and sizes) and their metaphorical ability (imagining what would go where) to accomplish the task. They're called dry stone walls because they don't use any mortar. Many have stood for thousands of years. At Glendalough in Ireland. . .
. . . monks built such buildings over decades, and used them over centuries. Sure the roof fell in when it was no longer maintained, but you could put a roof up and use the building again tomorrow.
Claims about high technology beyond the abilities of "primitive" humans are always based on an implied assumption that humans thousands of years ago were somehow not too bright. That they didn't have the intellectual abilities which we have. That's horseshit. (Maye you think your ancestors were stupid, but I don't think mine were.) Homo sapiens sapiens
(it means man who knows he knows, and refers to self-conscious intelligence) has been around for many tens of thousands of years. Humans weren't a bunch of plodding dopes who suddenly got smart a few centuries ago. Maybe you're OK with this inferential insult, but it doesn't appeal to me at all.
Monumental architecture does not require high technology. It requires the patient application of intelligence, time and labor--like dry stone walls--on a larger scale than a farmer building a wall. Naked-eye astronomy (which you mentioned elsewhere) is not evidence of any technology at all, and it has almost always been wrong throughout the ages--such as not understanding the "stars that go backwards" which the Greeks called planētēs
, meaning a wanderer. They simply had no frame of reference to see how those "stars" moved in relation to earth and the sun. As soon as they had reliable telescopes, humans began to connect all kinds of dots.
All this crap about high technology is a dog and pony show from people like Erich von Däniken. He was convicted of theft at age 19, and published a bullshit story about ancient astronauts in a minor publication in German before being convicted of fraud and embezzlement. Then he got smart and published his ancient astronauts bullshit in English, and made a fortune. Now he didn't need to defraud and steal. Plenty of other people since that time have picked up that ball and run with it. Our ancestors were not a pack of stupid, clumsy monkey-men who needed ancient astronauts to accomplish big things. They needed time, patience and a lot of labor.
The usually got the latter by suckering people with religious bullshit.
