Is it possible an ancient civilisation capable of shaping stones using advanced power tools existed in the distant past? Could this civilisation have predated all known cultures associated with megalithic sites around the world to this day? According to a Russian researcher the answer is most definitely “yes”: That’s the conclusion of Andrej Sklyarov, a Russian researcher who – like Christopher Dunn – has a background in mechanical engineering and inspected various tool marks and other peculiar features exhibited in stonework currently attributed to cultures who are said to have fabricated these mega structures using copper chisels, stone balls and other primitive tools. The video below provides an overview of his findings: Although the clip has been around for some time (and has been mentioned on ATS before) it has never been subject of a thread of its own, as far as I know. Interestingly, Sklyarov first introduces the hardness scale of different stone types, explaining that tools need to be harder than the materials they are applied to. However, he also points to the fact that copper tools would require an abrasive like quartz sand in order to work a harder material such as granite. Yet, the alleged use [...]
