Puma Punku is considered to be a complex of ritual buildings dating back to the 5-6th centuries AD. Accordingly, scientists believe that it was built by the ancient and primitive Indians. However, many facts point to a very high level of development of its real builders.
During the construction of the complex, slabs were used, the weight of which often exceeded tens of tons. The largest of them have an approximate weight of 131 and 85 tons (I cannot find them from photographs (they are not signed anywhere), but information is from Wikipedia).
That is why the ancient Indians used such huge monolithic slabs? There was no need for this. They could not cut and move them normally. But the complex stands, and this is a fact.
I found an interesting photo on the Internet of how, in theory, this complex should have looked initially. In the article, along with this photo, you can find information about slabs weighing 400 tons!

Now it is impossible to determine the exact weight of many objects, since the complex is badly destroyed. By the way, no one knows who destroyed it and when.
Briefly about the most important
It is highly probable that the complex was built by an unknown highly developed civilization long before the Indians who found it. This is directly evidenced by the highest quality of processing of its elements and the complexity of the architecture.
If the primitive Indians could build in this way, then there are clearly some huge gaps in our history. Take a look at the photo.
Here are some more illustrative examples of block processing.
I cannot miss a moment with the nature of the destruction of the complex. There are hundreds of multi-ton blocks scattered around like small bricks. Who or what is capable of causing such damage?
I assume that this complex was an important building in ancient times, because of which it was destroyed as a result of the war of the gods.
I forgot to add, the reconstruction of the complex in the photo above may not be accurate, so we cannot exclude its more complex and sophisticated form for unknown purposes. Probably, this required such huge slabs of several tens of tons.
