There appear to be signs of ancient machinery and engineering that equal and sometimes even surpass the capabilities we have today. All around the world we find signs of high-tech precision hole drilling into hard rocks such as basalt, limestone and granite.These cannot be explained with the tools that were supposedly used by the ancients. What follows are a few examples from ancient Egypt. Note the spiral grooves:
According to conventional Egyptology the ancients responsible for these structures were only equipped with simple chisels and manually turned tube and bow drills. Is that really possible by hand? Not to mention the countless perfect squares, rectangles, circles, smoothly polished surfaces, contoured angles also found at these sites.
Many books and websites out there explain how it was supposedly done, but, as far as I can tell, fail to replicate the procedure with those tools in real life. Here, for a typical example, we find a picture of one of the Egyptian bow drills:
Quoting from some of the accompanying (and quite typical) text:
In Egypt, a number of carpentry bowdrills have been found that were used by the ancient Egyptians (Fig. 1, Petrie 1974a). The bow was much wider at one end to allow for a handhold, and the drill-stock was made of wood, and sometimes contained a discharge hole to help eject the drill bit (Petrie 1974a, image). The capstone bearing was of wood or hard stone, and had a hole in one end for the insertion of the drill-stock. An example of a modern experiment in fire making using a replica of a small ancient Egyptian bowdrill is presented in the following website.
But the website linked to does not show the results of this type of drilling. Where are the exact and tight spiral grooves? And how a rock attached to the drill going to cut a perfect circle through granite? The site admits:
Copper and bronze are insufficient in terms of indentation hardness to cut by abrasion the majority of minerals in hardrocks such as basalt, diorite, granite, metagreywacke(slate/schist), and siliceous sandstone (quartzite). A harder material than the metal itself is required as an abrasive in order to cut these rocks.
My point exactly. So where is the evidence of a harder material having been used? They go on to say:
Stocks (2001) constructed a partial rotary-motion coring drill powered by a wooden bow (Fig. 20). The coring barrel was made of copper and was 8 cm in diameter, 1 mm in thickness, and was partially forced fitted to the wooden drill-shaft. A capstone bearing was carved out of a hard sandstone with flint chisels and punches, so that the rounded cone end of the drill-shaft could rotate with reduced friction when aided by grease, as well it acted as a weight. The wooden bow was made from a curved tree branch that applied enough tension to the bow rope to prevent slippage of the wooden drill-shaft during the coring experiment.
And where can we find pictures of the results that at least match those of the ancients? My point is: This and many other documents claim that experiments were conducted to replicate ancient drilling with manual tools, but having searched the Internet I couldn’t find a single sample or result that equaled those of the ancients. I am no expert (on anything, for that matter:-)), but my guess is that no photographs of the results can be obtained because the results are insufficient. I’d like to go out on a limb here and say that it’s not possible to drill these kind of holes into granite with manual tools!
I looked up “how to drill a hole into granite” on the Internet and found a WikiHow page describing the process (bolding mine):
Granite counters and flooring are popular among homebuilders and homeowners because of the material’s attractiveness and durability. Granite comes in a wide variety of colors and finishes and, despite being somewhat more expensive than most alternatives, it continues to be among the most popular materials in high-end building and remodeling projects. Because of its hardness and relative brittleness, however, granite can be a tricky material to work with: You need special saws to cut granite tiles and industrial-level saws to cut counter-thickness pieces. It also takes special care and tools to drill through granite. The wrong method or drill will likely result in either ruined drill bits or cracked granite.
The page then continues to show how relatively small holes can be done with high-speed diamond heads, in addition to several warnings about the rock chipping. So even with industrial-style drills and on small holes, it`s a difficult task.
Unless I am mistaken, that would leave us with the conclusion that someone with high-tech equipment drilled them. Maybe the Egyptians knew more than we suspect. But if they did, the knowledge was lost, otherwise Egyptians would have become the foremost experts on drilling. Knowledge that was clearly present in the distant past had become lost over time. The first pistol grip, portable electric drill was invented by Black & Decker in 1917.
I asked questions about hole-drilling to a curator at the Egyptian Museum in Cairo ten years ago. He didn’t even know the holes existed. Then I asked a professional Egyptologist. He was aware of the holes but said they haven’t been explained yet. “Just because there is no explanation yet, doesn’t mean it was aliens” was his casual reply. And I agree. I don’t automatically assume that anything unexplained = aliens. It could have been humans. An unknown method could have been employed. Nonetheless, even if no aliens were involved it does raise the question who was. As I demonstrate in my book “Atlantis and the Garden of Eden”, high-tech appears to have been available before the flood and become lost post-flood.
Here are some ancient hole-drilling feats from Peru (Puma Punku) and Bolivia (Tiahuanaco):
The following piece (image below) is attributed to Celtic Ireland. It is not quite as mysterious as the pieces already shown, but still raises questions. I quote from an external article (bolding mine):
This ceremonial macehead, found beneath the eastern chamber tomb at the great passage tomb at Knowth, in the Boyne Valley, is one of the finest works of art to have survived from Neolithic Europe. The unknown artist took a piece of very hard pale-grey flint, flecked with patches of brown, and carved each of its six surfaces with diamond shapes and swirling spirals. At the front they seem to form a human face, with the shaft hole as a gaping mouth.
If it was made in Ireland, the object suggests that someone on the island had attained a very high degree of technical and artistic sophistication.
The archaeologist Joseph Fenwick has suggested that the precision of the carving could have been attained only with a rotary drill, a “machine very similar to that used to apply the surface decoration to latter-day prestige objects such as Waterford Crystal”. If this is so – and it is hard to understand how the piece could have been made otherwise – the technology predates that used in the classical world by 2,000 years.
The following was found on a site of the Hittites (described as Atlantis-descendants in my book) of Anatolia. Archaeologists report that these holes have been found all over Hittite sites and that their contours are so smooth that they look as if made through modern precision drilling.
As explained in my book, until about a hundred years ago, the Hittites, were considered “mythological” – until their remains were discovered. They reigned 3000 to 4000 years ago. Searching the Internet I could find no sensible explanation of their drilled holes.
There seem to be a lot of holes in our conventional theories of ancient History though.
