Prehistoric High Technology
Claims that ancient structures display evidence of advanced machining, precision and technology beyond known historical capability.
Sites like Puma Punku, the Serapeum and Baalbek show stonework requiring tools or techniques unknown in their period.
Precision-cut andesite at Puma Punku, the Serapeum's granite boxes, and core-drilled artefacts in Egypt are cited as evidence of advanced methods.
Experimental archaeology has demonstrated that stone, copper and bronze tools can achieve remarkable precision with sufficient time and skill. No machine tools have been found.
The absence of any tool or machine remains is a significant gap. Marks attributed to power tools can often be reproduced with hand tools and abrasives.
The exact techniques used at some sites remain uncertain, but no evidence of machine technology has been confirmed.
