Editing Ancient Aliens — Puma Punku and Tiwanaku (section)

=== The H-Blocks and Precision Cuts ===
The most dramatic physical evidence cited at Puma Punku:

* '''H-blocks''': A series of H-shaped andesite and red sandstone blocks with precise geometric cuts, smooth surfaces, and interlocking channels
* '''Drill holes''': Some blocks feature holes and channels that appear to require precision drilling
* '''Identical shapes''': Multiple apparently identical blocks suggest either industrial-scale template manufacturing or advanced machining
* '''Tight tolerances''': Blocks fit together with minimal gap, suggesting precision fitting comparable to modern masonry
