Scattered across ancient sites in the Andes, from the cyclopean walls of Sacsayhuamán to the forgotten quarries of Ollantaytambo, lie granite and diorite stone blocks that bear a silent, yet deafening, testament to a lost chapter in human history. These are not just the familiar, perfectly fitted megaliths of the Inca; these stones are marked by a technology that seems to defy the accepted timeline of human development. They are scarred by deep, precise drill holes that, according to some geological and archaeological analyses, may be as old as 12,000 years.

The holes themselves are the heart of the mystery. They are not rough, percussive pits, but clean, cylindrical bores that sink inches deep into some of the hardest stone on Earth. In some instances, the drill bit appears to have plunged into the rock with astonishing ease, as if the granite had the consistency of soft wood. Even more baffling are the cores that were sometimes left behind—solid, stone cylinders that would have been sheared off from the inside of the hole. The spiral groove etched into the sides of these holes and cores suggests a drill bit of immense power and consistency, applying steady, relentless pressure.

To stand before these stones is to confront a puzzle that orthodox archaeology struggles to solve. The conventional narrative tells us that at the end of the last Ice Age, humanity were hunter-gatherers, only just beginning to experiment with agriculture. They wielded tools of bone, wood, and chipped stone. They did not, by any known account, possess machinery capable of drilling into granite with such surgical precision.

This discrepancy gives rise to profound questions. What civilization, or what knowledge, existed in a forgotten prelude to our known history? Was there a culture with a technological prowess that was later lost to cataclysm or time? The nature of the holes suggests a process beyond mere manual labor—perhaps ultrasonic drilling, advanced abrasive techniques, or a technology we have yet to rediscover.

These drill holes, therefore, are more than just curiosities. They are permanent question marks carved into stone. They challenge the linear progression of history and force us to consider the possibility of rises and falls of civilization long before our own. The smooth, spiraling grooves are like fossilized whispers, hinting at the hum of ancient machinery and the shadow of engineers whose names and world have been utterly erased. They remind us that the past is not a neatly written book, but a landscape riddled with deep, unexplored holes, leading into the darkness of our own forgotten origins.
