>>40868501I'm pretty convinced about the existence of lost advanced ancient civilizations, but I think a lot of the speculative theories about how things fit together simply don't have a wide enough scope, or get too stuck into weird schizo nonsense like aliens.
The convincing evidence I have seen for advanced ancient tech are high precision stone objects, like Egyptian hard stone vases and other precision cut stone boxes, the pyramids themselves, the Barabar caves in India, and a few anomalous mesoamerican artifacts that seem precision cut from obsidian (spool like shapes)
The megalithic walls in your picture are interesting but seem to be different in technique and style to the precision cut objects I mentioned previously, they also seem to me to be the product of a more advanced ancient culture but one that is significantly different than the precision objects and truly monumental stone blocks like in the pyramids and various underground Egyptian sites.
Alfredo Gamarra categorized the Andean stone ruins into three groups, Ukun Pacha, the dry stone construction with smaller stones constructed on top of older polygonal megalithic walls, like your pic, which he called Uran Pacha, and then the third group, Hanan Pacha, refers to absolutely massive stones that have intricately cut sections, and usually lie underneath Uran Pacha, often sort of protected by it, and these massive stones usually have a lot of damage to them, are sometimes flipped over or misaligned, or out of place. Other similar megaliths have been found in Portugal, Turkey, Mexico, Israel, Japan (see the Nara megaliths), China (Yangshan monolith), but these regions also often have the polygonal masonry walls (Uran Pacha) from a later phase of civilization.
