I understand your conclusion...just comes down to whether one comes to believe one or the other. What is your opinion on Puma Punku stones Martin? As per a different thread, I wonder if some of those blocks weren't indeed some kind of poured mold. ? Your 'side' if I can call it that, would have us believe that it was done with some kind of pounder/abrasive sort of tool to create. If I understand you anyways...

I take it you've watched Dunn's video's. Interesting how we came to such vastly different conclusions ie:

yours: Dunn is clearly wrong and completed with low tech etc.

mine: Dunn completed 3 different types of tech and viewed under high power'd magnification and conclusion was cut by a saw.

Dunn's a great thinker...hard to think out of the box and rare to find someone who does - and with logical/scientific supported reasoning.
