The Evidence is Cut in Stone: A Compelling Argument for Lost High Technology in Ancient Egypt

Most people know of the great construction achievements of the dynastic Egyptians such as the pyramids and temples of the Giza Plateau area as well as the Sphinx. Many books and videos show depictions of vast work forces hewing blocks of stone in the hot desert sun and carefully setting them into place. However, some of these amazing works could simply not have been made by these people during the time frame that we call dynastic Egypt.

Up until the 7th century BC there was very little iron present in Egypt, as this material only became commonly used once the Assyrians invaded at that time; in fact, the ancient Egyptians regarded iron as an impure metal associated with Seth, the spirit of evil who according to Egyptian tradition governed the central deserts of Africa. A few examples of meteoric iron have been found which predate the Assyrians, but this consists largely of small ornamental beads.

The very basic problem that arises is that we find at many of the ancient sites in Egypt finely crafted works in basalt, granite, quartzite and diorite which are very hard stones that can't be shaped efficiently even by hardened iron tools. For most of the history of Egypt, the tools used to shape stone consisted of hardened bronze, which is much softer than iron. In this article, we will see examples of ancient hard stone workmanship which simply could not have been created during the dynastic Egyptian time frame of about 2500 to 1500 BC, when most academics believe they were made. Only a few examples will be discussed, and far more can be seen and read about in my Lost Ancient Technology Of Egypt book.

A Famous Unfinished Obelisk

We start in Aswan, which is close to the border of Sudan, and it is here that we find the famous unfinished obelisk, and another smaller one, still attached to the granite bedrock.

Archaeologists claim the female ruler known as Hatshepsut, who came to the throne in 1478 BC sanctioned the construction of the bigger of the two. It is nearly one third larger than any ancient Egyptian obelisk ever erected. If finished, it would have measured around 42 m (approximately 137 feet) and would have weighed nearly 1,200 tons. The greatest questions that arise are: what tools could have been used to shape this massive stone monument, and how were the Egyptians planning on raising it out of the pit in which it sits, taking into account its immense size. To the former, most Egyptologists believe that round and hand-held stone dolerite pounders were the main tools being used.

In basic terms, any tool should have a greater hardness than the material being cut or shaped. The pink granite of which the unfinished obelisk is composed has a Mohs hardness that sits between the scale of 6 and 7, (the maximum being diamond at 10) and thus is more or less the same hardness as dolerite, making the latter a poor material for shaping the former. And bronze, the other tool substance known to and used by the ancient Egyptians is much softer, being on average 3.5 on the Mohs scale.

Other problems encountered at the unfinished obelisk is that there is very little room inside the trench to be able to create a hard blow, and such repeated efforts could also break the dolerite tool. According to engineer and expert machinist Christopher Dunn, author of Lost Technologies of Ancient Egypt: Advanced Engineering in the Temples of the Pharaohs:

'The unfinished obelisk offers compelling indirect evidence regarding the level of technology its creators had reached – not so much by indicating clearly what methods were used, but by the overpowering indications of what methods could not have been used.'

What Tool Did the Shaping?

The idea that hand held pounders were responsible for the shaping of the unfinished obelisk has to be dismissed, and yet, what kind of technology could possibly have been responsible? Chris Dunn's opinion is that if one observes the pattern left by the tool which did the actual shaping, especially in the walls of the trenches that surround the unfinished obelisk, there is an even pattern which would unlikely have occurred if hand tools such as the pounders were used. According to Chris:

'The horizontal striations are typical in cutting when the feed of a tool that is removing material pauses along its path, withdrawn to remove waste, and the interruption of the tool leaves a mark on the surface. Also, it could be that as the tool was rocked back and forth against the walls of the trench to clear the waste on the vertical wall, horizontal striations appeared where the tool pressed the cutting surface against the side wall to keep the trench from narrowing.' In other words, some form of technology which the dynastic Egyptians simply did not have. And so this begs the question; if the dynastic Egyptians could not have done this work, and the later Greeks and Romans were not responsible, then who did and when? We have no choice but to entertain the idea that a civilization existed before what we call the pharaohs and in fact had forms of what we would call high technology, and that these people lived in the area prior to 3100 BC.

Many will of course ask where the tools are that could have done work such as this. We do know that strange devices and materials have been found in archaeological sites in different parts of the world, and have been labeled, boxed and hidden out of view because they do not fit the conventional historical paradigm. Sir William Flinders Petrie was one of the great Egyptologists of the late 19th and early 20th centuries. Petrie found a number of core drills, many of which are now housed in the museum named after him at the University College London in London England. The actual hollow drill bits have not been found, but the cores made of limestone, alabaster, granite and other stones have.

Chris Dunn spent hours in the Petrie museum and was allowed to personally examine some of the drill cores. Here he discusses the characteristics of one of them:

'The most fascinating feature of the granite core Petrie describes is the spiral groove around the core indicating a feed rate of 0.100 inch per revolution of the drill. It was 500 times greater than modern diamond drills, but the rotation of the drill would not have been as fast as the modern drill's 900 revolutions per minute.'

The often times quoted idea that these drill cores were achieved using a bow and copper tube with sand used as an abrasive must be thrown out, as no modern replication of these cores has been done to the level of efficiency as discussed above.

Making excavations in 1936, in the archaeological zone of Saqqara, Petrie discovered the Tomb of Prince Sabu, who was the son of Pharaoh Adjuib, governor of the I Dynasty (3,000 BC). Between utensils of funeral objects that were extracted, Emery's attention was powerfully drawn to an object that he initially defined in his report on the Great Tombs of the I Dynasty as: 'a container in the form of schist bowl.' Years later, in his previously mentioned work, Archaic Egypt, he commented on the object with a word that perfectly summarizes the reality of the situation and the discomfort the object causes; "cachibache" (a small hole that threatens to become a much larger hole.)

According to the typical and expected view of the archaeologists and Egyptologists, this object is no more than a tray or the pedestal of some candelabrum, with a design a product of blind chance. I am personally quite amazed that such a controversial piece is still on display in the Cairo museum, and wonder what even odder objects are hidden away in their warehouses.

At Karnak, which is a huge temple complex, we find many examples of ancient core drill holes, and one whose diameter is greater than a human hand. As you can see in the photograph the wall of the drill itself was thinner than 21st century examples, and even engineers and mining experts that have seen it cannot explain what material the drill would have been made of to maintain its shape and stability at being so thin.

Massive Granite Boxes

Another perplexing site is what is called the Serapeum at Saqqara, containing massive granite boxes which many academics believe were created during dynastic times. However, the boxes in the Serapeum are examples of what engineers such as Chris Dunn, I, and members of the Khemit School have major problems with as regards the conventional Egyptologists’ explanations. According to the latter, in the 13th century BC, Khaemweset ordered that a tunnel be excavated through the solid limestone bedrock, with side chambers designed to contain large granite sarcophagi weighing at least 70 tonnes each, to hold the mummified remains of prize Apis bulls.

Manufacturer Chris Dunn is a man who knows what precision surfaces look like, as he has been involved in making complex metal parts for the aviation industry for decades. He has studied the boxes in the Serapeum many times, and has been able to measure the flatness of their granite and limestone surfaces using precise gauges. The following are his thoughts, as found in an article on his website

'The granite box inside Khafre's pyramid has the same characteristics as the boxes inside the Serapeum. Yet the boxes in the Serapeum were ascribed to the 18th dynasty, over 1100 years later when stone working was supposedly in decline. Considering that this dating was based on pottery items that were found and not the boxes themselves, it would be reasonable to speculate that the boxes have not been dated accurately. Their characteristics show that their creators used the same tools and were blessed with the same skill and knowledge as those who created Khafre's pyramid. Moreover, the boxes in both locations are evidence of a much higher purpose than mere burial sarcophagi. They are finished to a high accuracy; their corners are remarkably square, and their inside corners worked down to a dimension that is sharper than what one would expect to find in an artifact from prehistory. All of these features are extremely difficult to accomplish and none of them necessary for a mere burial box.

The manufacturers of these boxes in the Serapeum not only created inside surfaces that were flat when measured vertically and horizontally, they also made sure that the surfaces they were creating were square and parallel to each other, with one surface, the top, having sides that are 5 feet and 10 feet apart from each other. But without such parallelism and squareness of the top surface, the squareness noted on both sides would not exist.

Staggering Implications

While it may be argued that modern man cannot impose a modern perspective on artifacts that are thousands of years old, an appreciation of the level of precision found in these artifacts is lacking in archaeological literature and is only revealed by an understanding what it takes to produce this kind of work. As an engineer and craftsman, who has worked in manufacturing for over 40 years and who has created precision artifacts in our modern world, in my opinion this accomplishment in prehistory deserves more recognition. Nobody does this kind of work unless there is a very high purpose for the artifact. Even the concept of this kind of precision does not occur to an artisan unless there is no other means of accomplishing what the artifact is intended to do. The only other reason that such precision would be created in an object would be that the tools that are used to create it are so precise that they are incapable of producing anything less than precision. With either scenario, we are looking at a higher civilization in prehistory than what is currently accepted. To me, the implications are staggering.

This is why I believe that these artifacts that I have measured in Egypt are the smoking gun that proves, without a shadow of a doubt, that a higher civilization than what we have been taught existed in ancient Egypt. The evidence is cut into the stone.'

What we also have to take into consideration is that most of the boxes in the Serapeum were made of granite, and most likely stone brought from the quarry at Aswan, about 500 miles from Saqqara. Not only that, but the lid of each box was cut from the same stone as the box itself. Why would the makers go to such trouble if bulls, no matter how prized, were the contents? It would appear, as Dunn alluded to, that the Serapeum boxes were not created in the 18th Dynasty and not by the dynastic Egyptians at all, but are remnants of an older and more technologically sophisticated culture, possibly those that are known as the Khemitians.

What you have seen and read here are but a few of multiple examples of artifacts that do not fit the paradigm of the dynastic Egyptians. These artifacts could not have been created by these people, and thus we must conclude that they are older.  More information can be gleaned from my book Lost Ancient Technology Of Egypt.

This contention of boxes being too precise and too important for just mummies of bulls pointing to their more recent adoption by such fetishistic pagans, follows the feeling I have always had that the pyramids were NOT built by those who later claimed in stone that they were at all, but by an earlier culture who came upon them later and used them and redecorated and added to them for their own cult.

In the same way, the story of pyramid construction is too far-fetched. Yes dictators etc seem to be able to coerce entire populations into catastrophic wars etc, but destruction requires no work and no talent-just the weaponry .

So it is with Egypt. Speculation akin to archeology of course, but equally plausible, surely?

I agree with the thought that there must have been a previous global civilization that fell either before or during the last ice age. There is so much proof that traditional archeologist try to bury. A previous civilization makes much more sense to me than ancient aliens. I think it was survivors from the previous civilization that helped our ancestors.

Also, the Ancient Egyptians were known to claim that the deeds of earlier pharaohs as their own, especially during their own dynasty. I’m certain that Khufu etc. did not build the structures on the Giza plateau, although I believe Khufu did recarve the sphinx head to resemble his own. What an ego he must have had.


The Hopi Indians said the Earth was remade four times and each time, humans were wiped out, so I believe we are the fifth act. I'm beginning to put it all theatergoer, but it seems to me the last
great catastrophe forced the multitude of humanity underground, hence the huge network of tunnels that can be found on most continents. My only guess is when we (humans) ran out of food, we resorted to cannibalism to survive and once we were able to ascend to the light, I believe that due to much of the world as we knew it being destroyed and the severe distress of surviving underground for so long made the survivors decide to start over and forget the past. That is my guess anyway, but of course without tons of bodies holed up in these tunnels, it's difficult to confirm this other than observing the evidence that's currently available throughout the world of a singular worldwide religion and architect designing pyramids on every major continent. I can't imagine such a terrible catastrophe to make us completely forget our past except what I mentioned.

This goes back to Graham Hancock and others who have shown with archeoastronomy that time periods assigned by academic Egyptologist for the pyramids and sphinx were constructed centuries before the Egyptians.

I often see the type of article that suggests an ancient alien unknown technology produced something we can't explain...which they recorded by carving stone with a chisel and hammer...! Anyone else see the irony in that? :) It would be like building the most amazing aircraft in LA and then decide to get to New York by horse instead.

In today's world if you wanted to preserve your thoughts for future millennium would you use stone carved deep or a paper product?
Do you not see the irony in your own statement IJ?
In the Indian Epics they speak of amazing aircraft and until recently they were on horseback.
If you do not remember your past you will lose it and the knowledge of it.

@Chris Dunn *cough* lapping *cough* Not wooooooooooAliens .... you throw enough manhours with basic tech you can accomplish great feats. If you sit some schlub in a quarry or finishing yard, with a little boy as a runner bringing sand and water, and sit there and hand lap a surface using a slab of tree as a gauge you can get a wonderfully flat surface. Just takes 3 weeks instead of 30 minutes.

We need MORE experimental archeologists, not people looking at modern industrial machines and assuming mechanical perfection.

When the end product is measured with precision tools, and it conforms to precise angles and surfaces, there is no "assuming mechanical perfection" If you don't have precision mechanical tools to do the cutting and finishing, you also don't have the precision tools to gauge the finished product. If all you have are dolomite pounders and bronze chisels, you will never get exact angles and mathematically flat surfaces no matter how many man-hours you throw at it, because you have no way of measuring them.
Your argument holds no water.

As a machinist I have to agree. Although I've done some high precision work by hand, without the tools to measure the progress, one would simply not be able to gauge success. I could have laid out the base of the pyramid with a piece of string (or wire) to within inches by simply measuring from the opposing corners (=). Working a substance with a hardness of 6 - 7 would take a very long time and be subject to repeated attempts. I do believe that holes could be drilled accurately with a copper pipe--I've done it through glass, but how do you make a straight piece of copper pipe? You must begin with an accurate standard, where is this measuring instrument?

Many archeologists, anthropologists, "bone hunters", etc. have been puzzled by the distinct gulf between sites all over the world and the "understood" primitive culture of early humans using those ruins, structures, etc. The answer has been "under our noses" all t he time, even though the Roman Church from Constantine to today has worked tirelessly to keep it hidden. We are told in Genesis 6 of the Bible that some of the angels who were kicked out of the dimension where YHWH was, decided to go to earth and take human women to have descendants. That action and the subsequent progeny - giants, various combinations /chimeras of fallen angels & human, or animal or two or more animals were real, were experienced by humans and recorded in their histories/oral traditions - as Titans, giants, Satyrs, Minotaur, Kraken, etc. and similar beings in otherr countries - Assyria, India, China, etc. Fallen angels told teh arious people they were from other places - like other planets, etc. and they were her to "help" - The multiple generations of their progeny ruled all over the earth and maintained some of the supernatural abilities of their fathers. Thus they knew how to move multi hundreds of tons stone blocks to build the unexplainable structures in Egypt, Peru, China, British Isles, Bosnia, Russia, India, as well as both poles. It is only modern man's inflated opinion of himself that makes the answer that is staring them in the face hard to accept. Yes, there was a flood to rid the earth of the horrors created and horrible behaviors of the giants - eating people, etc. But evidentialy, they still had enough skills and knowledge that they could escape and position a few of themselves around the planet again. So although YHWH had Joshua and the Hebrews out of Egypt to destroy lmany villages in Canaan, but not all, because they were descendants of the giants of old and their blood was polluted. Conquestedors to S. America found giant bones, and many items of the giant rulers. Their written accounts confirm that the Inca told them they did not build the great structures - they were there when the Inca's ancestors arrived. Interestingly, now, the megalithic structures, pyramids, etc. are "popping" up everywhere! New ones like the Bosnian pyramids, and cities sunk in the sea off of Cuba/S. America and off China, hidden under snow in the N. pole, the great earthen works in N. America, Native American stories passed down through hundreds of generations are ALL waiting to be explored with "new eyes" and "open minds"!

Just because something is made to more accurate specifications than most artisans would do, does not mean that the tools used to do it were "incapable" of doing anything except the most precise work...

Once upon a time, people cared deeply about what they made. Perfection was a sign of the master of the craft. People took pride in the work they did. There have also been secret societies through the ages that have had extensive focus on the sacredness of perfect geometry.

That sort of thinking didn't start with Pythagorean Mystics. Utilizing sacred geometry and the creation of perfect angles in structures, and lining things up with the stars is a very ancient concept...

This doesn't mean that the ancient Egyptians didn't have advanced tools... but the idea of basing the premise that they DID on "well, artisans now wouldn't go to all of that trouble unless they had to, so the fact that these ancient people made something so precisely means that their tools couldn't have allowed for anything less than perfection" is flawed.

The craftsmen of the time DID have to make everything to perfection. These people were the priests of their craft. Their pride wouldn't allow for anything less, regardless of how long it would take. That is what it means to be genuinely proud of the work you do.

Again, this doesn't mean that the ancients didn't have advanced technology, they likely did... but people these days are lazy, and don't do the extra work to make things perfect, because they aren't expected to, and aren't going to be recognized for their achievements even if they did.

"Perfection was a sign of the master of the craft."
Perfection is also a sign of the tools available to the artist.

"Utilizing sacred geometry and the creation of perfect angles in structures, and lining things up with the stars is a very ancient concept."

This still requires precision tools to create physical objects that conform to those mathematical principles.

FTA "In basic terms, any tool should have a greater hardness than the material being cut or shaped. "
That is wrong.

This is correct.
"Why soft grinding wheel is used for hard material
A grinding wheel consist of abrasive particles which are large in number and they can be hard or soft .a soft grinding wheel is used for hard material because the weared abrasive can come out and give it space to incoming abrasive."

The "abrasive particles" on the "soft" grinding wheel are still harder than the material it is used on.

Considering how quickly iron tools rust, seems like it would make sense that we aren't seeing remnants of those tools when excavating these sites.

There are those who claim that Z.Sitchen was a fraud and confessed at the end of his life that he made it all up. But if you really look at what he wrote, you may find that his "version" of the story is the only one that answers just about all the questions as to who, how, when, and why better than any other version of telling.For what ever liking or disliking an individual researcher or writer in the end I must look at what they wrote and if it applies to the query at hand. In his case, as with many other authors, I find his telling plausible and in fact perhaps the only writings to offer solutions to many problems within both mainstream and alternative archaeology today. By no means did he tell the whole story nor did he get it completely right on all accounts, but I think his writings merit another closer look in light of the constant new finds we keep encountering.

The speculation in the article was already laid out by the Argentine archeologist José Alvarez López in his works, more than forty years ago.

Ancient Places

From this map of the site, all the main structures and rock carvings are visible.
The little town of Malinalco lies at the margins of the Valley of Tepoztlan, some 115 kilometers (71 miles) to the southwest of Mexico City. Since Prehispanic times, its name has been associated with magic and sorcery: Malinalxochitl, goddess of snakes was worshipped on the Cerro de los Idolos, a hill overlooking the entire valley and the town below.
