Megalithic Precision Engineering

At Puma Punku in Bolivia, you find andesite blocks cut with tolerances of 1/100th of an inch. Surface flatness that rivals modern machining. With bronze tools? The mainstream explanation doesn't match the physical evidence.

I analyzed photos of the H-blocks at Puma Punku. The standardization suggests modular design - like ancient LEGO. Identical dimensions across multiple stones means they had precise measurement systems and possibly templates or molds.

But absence of evidence isn't evidence of absence. Just because we haven't found advanced tools doesn't mean they didn't exist. What if they used organic tools that decayed? Or techniques we haven't considered?

Christopher Dunn proposed ultrasonic drilling and precision sawing. His book "Lost Technologies of Ancient Egypt" documents tool marks that match modern machining patterns, not ancient copper chisels. It's controversial but the evidence is worth examining.

What humbles me is how little we know about human capability. Every few decades, archaeology pushes back the timeline of "firsts." Perhaps advanced knowledge is less about steady progress and more about rediscovery of what was once known.
