We are not talking about 1 stone, we are talking about a temple site that, according to Wikipedia:

"At its peak, Pumapunku is thought to have been “unimaginably wondrous,”[2] adorned with polished metal plaques, brightly colored ceramic and fabric ornamentation, trafficked by costumed citizens, elaborately dressed priests and elites decked in exotic jewelry. Our understanding of this complex is limited due to its age, the lack of a written record, the current deteriorated state of the structures due to treasure hunting, looting, stone mining for building stone and railroad ballast, and natural weathering."

I do not understand your question about "who is the eyewitness".

I think it is undeniable that whoever quarried, cut, polished, tooled, and transported these stones had far better tools than the indians living there today, the question is, why do we have not archaelogical evidence of them? Where did these tools go?

By way of comparison, there is an obelisk in Rome that came from ancient Egypt. It weighs 230 tons. It was erected in the 1500s. It was shipped by boat, and erected using cranes. It was a very big undertaking at the time. Puma Punku preceded this by at least 2,000 years, and whereas the stone in Rome is near sea level, these stones in Puma Punku had to be taken up a steep slope, 10km. There were no ships to transport them. No doubt, putting them in place would require cranes, but how did they transport the stones?

As for cutting, polishing and tooling in place. If we were to do this today we would need huge machines. I have a diamond tipped wet saw for cutting tile, that could not have made these marks, you would need a much bigger machine. We would probably need robots. The stones were designed to be interlocking like legos.

The stones are made of granite and diorite, which are very hard stones and would require a diamond tipped saw to cut.

So somehow, to explain this site you have to explain how a civilization in the Andes at least 2500 years ago had the ability to build this site.

The gives the following hypothetical explanations:

"Archaeologists argue that the transport of these stones was accomplished by the large labor force of ancient Tiwanaku. Several theories have been proposed as to how this labor force transported the stones although these theories remain speculative. Two of the more common proposals involve the use of llama skin ropes and the use of ramps and inclined planes."

Since those explanations don't rely on supernatural or unknown alien beings, everything else being equal, they appear more plausible.
