Have you ever heard of Naupa Huaca - one of the ancient monuments located in Peru. It is believed to have been built during the Inca era. This complex consists of two "portals", processed with amazing accuracy.
Between them are the remains of an ancient stone structure. The "portals" were made so precisely that it seems as if ancient builders used some technological tools that were clearly ahead of their time to create them. Here are just a few of the features of these "portals":
1) Their corners are very even.
2) The lines are perfectly straight.
3) The surface is polished so well that it is hard to believe that such an effect can be achieved with the help of improvised tools.
The first "portal" is like a false door and does not lead anywhere at all. Some researchers believe that the Incas really could have some kind of technology for traveling to parallel worlds, and in ancient times there could be a real portal.
Surprisingly, the niche for it is made very well and conveniently - a modern person will easily stand in it in full growth. Unfortunately, scientists have not been able to understand when this ancient complex was built.

And most importantly, for what purposes was it intended? Such buildings once again remind the official science of how little it knows about the history of the planet and mankind.
Not far from here there is another miracle created by the masters of antiquity - a stone that is made so smoothly and precisely that it seems as if it was passed over it with a powerful laser. It has a perfect geometric shape.
The most interesting thing is that this complex was built by Indians high in the mountains - about three thousand meters above sea level. It's very difficult to get here.
Why the ancient masters chose this particular place is not clear. However, modern researchers have discovered deposits of blue stone here. This stone contains certain crystals that have excellent piezoelectric properties.
Even in the last century, they were widely used in radio engineering. Also, in some cases, these stones may have magnetic properties.
Looking at all these straight lines, right angles and a smooth surface, one gets the impression that not hand tools were used to make such structures, but some ancient 3-D printers - all this was carved from monolithic rock, in fact by ancient craftsmen there was only one attempt and there was no room for error.
And similar things are found not only in Peru - throughout the entire territory of our planet. Take at least the same India with its famous Kailash temple, which is also carved from a single piece of rock.
It is unclear if they really used hand tools, then how did the ancient craftsmen manage to avoid mistakes?
The answer, it seems to me, is only one - their construction processes were pre-programmed and automated, i.e. this already indicates that they have some devices that have not come down to our time. Perhaps they have yet to be found.
