We do not claim to know how the heavy lifting and exquisite masonry was accomplished at Pumapunku, but that's a far cry from saying we believe the Tiwanaku were incapable of it. We simply don't have a record of what tools and techniques they used. All around the world are examples of stonemasonry from the period that is equally impressive. The Greek Parthenon, for example, was built a thousand years before Pumapunku, and yet nobody invokes aliens as the only explanation for its great beauty and decorative detailing that more than rivals Pumapunku's angles and cuts. At about the same time, the Persians constructed Persepolis with its superlative Palace of Darius, featuring details that are highly comparable to Pumapunku. Stonemasons in India cut the Udayagiri Caves with megalithic doorways that are very similar to those in Pumapunku. The Tiwanaku did magnificent work, but by no means was it inexplicably superior to what can be found throughout the ancient world. It is unnecessary to invoke aliens to explain the structures.
I hope I did this right.
*sticks fingers in ears* I can't hear you!!! La la la la la la! Aliens!
