Ancient "Stone-Cutting Machine" Links India & China?

While perusing the many perplexing sites we are yet to cover on our channel, we stumbled across something which could quite possibly be a massive clue, evidence left as to the method of construction of many ancient sites found all over earth. Our channel has, for a long time, put forward the hypothesis that a highly advanced, world wide, civilisation once flourished here on our planet. We believe that many of the ancient sites which display unexplained architecture, were left by this lost people placed far within our distant past. And once one begins to investigate these ruin with this possibility in mind, you start to notice some compelling things regarding these amazing sites. For example, the metal clamps we have previously covered, often created using impressive mixes of alloys and somehow poured molten, could now be seen as earlier architectural examples than the mortar-less, mysteriously notched stonework, also found in similar area all over the world, with the more precise, and thus more impressive stonework, seen as a later, more sophisticated method of construction. Whats more, not only their ancient stonework using bricks can be found still existing, although virtually all ancient sites have been dated to the most convenient suspects within known, taught history, there also exists the numerous caves and temples, hewn from the solid bedrocks, carved with such accuracy and vision, they elude recreation even by our modern-day technology. And while looking at an amazing rock cut cave within the site of Mamallapuram, India, a site we are now convinced was left by this same civilisation, a curious piece of evidence seemingly presented itself. Upon the roughly finished roof of this ancient cave, is evidence left by the same technology used to not only cut the astonishingly huge Longyou caves, but also the abandoned Yangshan Quarry both in China! This discovery, we believe, is only just the beginning of a realisation that these tell tale signatures are present at many other, unexplained sites around the world We have long stipulated that many of the ancient ruins claimed by our more modern day ancestors, are most likely, not their actual creations. If the structure does date to this more recent age, they are usually found to be sitting upon the tell-tale remnants of highly precise, ancient foundations, originally left by this illusive group.
Who were these amazing people?
When did they flourish here on earth?
What happened to them?
Why did they never record how they created such wonders?
Although it is easy for sceptics to argue that the caves and architecture, were merely created through excruciating hard labour, any practical demonstration of this has eluded us for many centuries...
Furthermore, many of the extensive cave excavations found all over the world, presumably dating back to this by gone age, are all absent any waste, its as if the machine tasked with creating these underground labyrinths, turned the stone to dust. And although the technology, and or possible machinery tasked with the job, has evaded modern archaeology to this point, it is clearly another piece of evidence which takes us one step closer to unravelling the true history of our planet!
