Large ancient monuments did not require lost supernatural technology. Archaeology reveals ramps, sledges, levers, ropes, water management, skilled labour and careful surveying. Different cultures developed different combinations of techniques.
What we found
Ancient engineering was impressive because people organised knowledge, labour and materials with great precision. Tool marks, unfinished structures, workers’ settlements and experimental archaeology show plausible construction methods. Some details remain debated, but uncertainty about one step is not evidence for aliens or vanished machines. The strongest explanation combines surviving evidence with methods that can actually be tested. The Ridbusters then compare the wording with the original sources, look for the conditions of each observation and check whether another explanation could fit. That turns a surprising headline into a trail a young investigator can follow: claim, test, result and remaining uncertainty. Large ancient monuments did not require lost supernatural technology.
