This very curious stone shows evidence of highly sophisticated alien technology. The stone is estimated to be millions of years old and yet it has perfectly round holes that were obviously created by someone who had access to advanced drilling technology. The dolerite stone was discovered near the Kitoy River in Russia. A dolerite is a volcanic rock. While similar to basalt, it contains crystals which can be seen with a hand lens. It is very hard and yet someone used impressive cutting-holes-in-stone technique that reveals our ancestors were familiar with an extremely advanced technology we have long been unable to use.As you can see on the images, the holes are perfectly round.Similar stones have been found in different parts of the world. Stones were drilled for architectural, ritualistic or symbolic functions..In 1996, this tube-drilled piece of granite was on display in the Cairo Museum without any associated identifying information. The image (below) clearly shows spiral grooves on the visible portions.The grooves can be seen to be of regular depth and spacing, and occur in all of the holes in this piece. As the holes overlap, were these grooves caused by abrasive slurry, they would not be expected to be so consistent.”These holes indicate a technology not developed for just this purpose, but for many earlier and easier purposes; generations of development over many projects, over hundreds of years. The craftsmen who did this had mastery of the principles of drilling round hollow holes in any material, soft or hard: wood, stone, or metal, and could have drilled virtually any naturally occurring material on Earth,” said W.M. Flinders Petrie (1853-1942), an English archaeologist and a noted Egyptologist.
