Another “anomaly” is that Puma Punku shows perfectly drilled holes, showing patterns that we are all familiar with in modern times. But the precision, shapes and accuracy of those stoneworks are barely imaginable without computer-assisted machinery. This is not speculation. It is simply admitted by archeologists or engineers who visited Puma Punku.
It is true that there are existing drilling techniques which could allow drilling in stones like andesite (7/10 on the Mohs scale of hardness) but as long as techniques remain hand-driven, they can’t reach Puma Punku’s level of precision, let alone on son many occasions.
For any type of activity, if the goal is reaching a certain level of precision, there is a need for appropriate tools required to assess whether the end result is reached. Meaning that they had to have similar equipment to what we use today to demonstrate how flat, precise, and regular their end work is.
The flatness of stones and the straightness of cuts are almost immaculate. According to engineer Chris Dunn, some surfaces of Puma Punku megaliths are within 2/10,000 of an inch of being laser flat. Such precision is not reachable with hand tools. Only highly advanced powered systems, deep geometrical and mathematical knowledge can allow such results.
