Ancient "High-Technology" Found In India?

There are a number of seemingly impossible ruins, and even still functioning temples, which can be found dotted all over India. Most of these structures, somehow conjured from solid bedrock or stone hillside with such accuracy, they baffle all who explore them. Whats more, there is also evidence left upon some of these structures, mysterious scarring, which not only suggests some form of machining actually having been involved in the construction, but these same mysterious marks can also be found upon ancient sites in other parts of the world. And while researching any other compelling fragments of evidence, that may have been left upon these ancient Indian temples, we have stumbled upon yet another ancient site. Also within India, which is displaying the same compelling, tell-tale signs of ancient machining, which was possibly responsible for the construction of these sites...The Hoysaleswara Temple in Halebidu is an incredible structure. Apparently built a mere 900 years ago, yet possesses columns and other features, created with such precision, they actually indicate the existence of advanced ancient technology. Discovered by Praveen Mohan, symmetrical grooves found upon many of the multi-ton, complex designed, temples columns. These grooves would be impossible to achieve using a hammer and chisel, thus they are a remnant left by another, unknown construction process, most likely a lathe. Additionally, although turning lathes were indeed in existence as far back as the 900 years ago, the accuracy of the grooves when they were made, the precision and symmetry visible,,, makes the columns seemingly impossible to have been created with such primitive technologies. Another curious discovery at the temple, is the curious gearing mechanism carved into one of the many decorative details upon the structure. In the hands of a god known as Masana Bhairava. is a clear representation a type of gear mechanism called “planetary gears.” As Praveen puts it, Quote, “The outer Gear has 32 teeth and the inner gear has exactly half the number or 16 teeth, which is precisely how we use reduction gears today. If this were just an imaginary tool, how could the ancient sculptors come up with this gear ratio of 2:1? Even more interesting, we can also see a fastener that goes around this mechanism and is locked in at the centre. Today, we use the exact same technology, we use something called a circlip lock or a snap ring to keep these things in place. If historians are right, how could primitive people, working with chisels and hammers imagine such a mechanism? End quote. It seems that the more we understand about the history of our planet, the more people begin to notice regarding the secrets of our past.
