I'll start from the very beginning. For me, the most striking example of holes in stones is Egypt, although in other places, of course, there are many similar finds.
In Egypt, a lot of both ordinary megaliths were found with holes that just roll around, and holes in various ancient structures around the world.
Of course, there are holes actually made with brass tools, sticks, etc. But such a minority and I can explain why.
It is worth saying that in stones all over the Earth, holes have a wide variety of diameters from very small (1 centimeter) to large, about 20 centimeters, and sometimes even more. They were made in the same way, of very different depths up to 4 meters, which is already difficult to explain with primitive tools.
But back to Egypt. If you consider many of these holes, they are often made in very hard stone. However, each of these even holes is internally machined along the entire diameter.
That is, it says that the holes were not made with primitive tools, but with something that rotated at great speed and perfectly polished the hole from the inside, that is, something like a drill.
Also, ancient civilizations somehow made shaped holes. 7 or 11-angle hole, for the civilization of the past it did not matter, and this was done in stones that are now lying around without any necessary use.

Moreover, some of the holes were made about 10,000 years ago, but traces have survived, and even parallel grooves inside the hole, which obviously cannot be made with primitive tools.
But now I want to touch on the official version of creating holes in stones. Allegedly, ancient people did this with sticks and sand, or other primitive tools, for a long time, but in the end they succeeded.
And if I say that many stones, both in Egypt and in other places, are now lying around without any use. That is, they spent a lot of time and effort on them, and then threw them? - It sounds stupid and I imagine the picture quite differently.
If this was a difficult process for the ancient people, they would use everything they could, but this is not so. Stones were often thrown as if they had made a hole in a couple of seconds, the stone did not fit and was thrown, that's how it all sounds much more believable.
Official historians, of course, can continue to tell these tales further and many, no matter how sad it is, believe in them. But to the simplest question, where there are ideally even furrows with the same pitch inside the holes, it is unlikely that someone will find an explanation, like a stick with sand or something else.
This is just one of the examples of high technologies of civilizations of the past, and they did it all over the planet and for many thousands of years, which means that then in many respects technologies allowed much more than official history says.
