Megalith, definition and study. A-Z index of Cognitio.

A megalith is a large stone or a set of stones used to build a structure or monument without the use of binders such as lime or cement. The megaliths present different forms and structures, even if we can identify some fundamental types such as the Menhir, a rough or just roughed block, driven into the ground and the Dolmen characterized by two or more vertical stones and a horizontal placed as a cover. There are also more complex megalithic structures, with real fortifications: it is the example of the acropolis of Alatri and of the nuraghe in Sardinia(Italy). Also in Sardinia it is possible to find other megalithic constructions used as tombs: the Tombs of the Giants.

Shocking truth

The term is used to describe structures erected by people’s in many parts of the world at different times. In the early twentieth century, the theory that most megaliths were the product of a global “Megalithic Culture” was widespread, but later dates have disproved this hypothesis. It has been hypothesized that some megaliths had the function of measuring or indicating important astronomical events, such as solstices or equinoxes. Some incisions on these stones have sometimes been interpreted as representations of specific stars and are believed to indicate the astronomical orientation of the structure.

“Imposing megalithic structures built with the help of alien technology? According to the theorists of the Ancient Astronauts it is possible. Here are the clues.

Ancient Astronaut

Without a little interplanetary help, how would the early Egyptians have learned to stack the nearly two and a half million blocks of limestone and granite that form the great pyramid of Giza?How could prehistoric man move the huge boulders of Stonehenge? Some blocks of granite are as big as a railway wagon and you can find them in Peru, Bolivia, Mexico and Egypt.

One must wonder how and why these ancient people’s dragged large blocks of stone like railway carriages to stack them on top of each other and create these gigantic buildings? 

The great pyramid of Giza

Cheops pyramid

Perhaps the most famous and mysterious megalithic structure in the world is the great pyramid of Giza, the oldest and largest of the three pyramids of Egypt. It is believed that this miracle of engineering was built-in a period of only 22 years, but for the theoreticians of the Ancient Astronauts the accounts do not return. In my opinion, it is not possible that the great pyramid was built-in such a short period of time, because if it were, logistically speaking, it would have had to cut, transport and fix a stone every 9 seconds! Modern engineers have come forward and confirmed that even today, with their advanced equipment, they could do it in 22 years. There is every kind of theory about how the great pyramid of Giza was built. Some immediately shake their heads, such as visits by extraterrestrials or the existence of an advanced Antediluvian human civilization. Instead we tend to believe theories that imagine thousands of workers pulling long ropes on a ramp that must have been at least 3 kilometers long to carry the stones where they are. The only thing certain is that the blocks are aligned so accurately and that the architecture is so precise that even today’s technicians, with a great technology, would be difficult to replicate this precision. Also, how did they build huge granite spaces, so perfect and so clean inside pyramids and tombs? Can we imagine that those works were made by hand? The enormous size and weight of the stones, multiplied by their number, make one thing certain: the construction of the great pyramid remains one of the greatest wonders and one of the greatest mysteries of construction engineering. I do not want to diminish human ingenuity, because I believe we have the ability to create similar masterpieces, but in a much longer time. There must have been a transmission of knowledge to our ancestors in order to realize these works.

Ancestors, the ancient aliens, communicated with them Original article by Alessandro Brizzi.


In Egypt there are ancient traditions that say that the great pyramid was built by a pharaoh named Saurit and they say that Saurit is the person known in the Jewish community as Enoch.

Enoch is a prophet of the Old Testament and reading his story in the apocryphal texts, it is possible to see a connection between his figure and the extraterrestrial beings.

Enoch clearly tells of having met them. In the apocryphal scriptures it is said that Enoch gives the order to build a building that can not be destroyed for thousands of years and the ancient Egyptian texts clearly say that the pyramids were built by human beings, but with the assistance of the guardians of the sky, that is, of the gods. One of the seven wonders of the world, the great pyramid of Giza, as well as for archaeology and engineering, remains a great mystery also for geography. In 1877, the writer and theologian Joseph Seiss demonstrates that the great pyramid stands on the intersection of the longest latitude line and the longest longitude line, at the exact center of the entire mass of emerged earth in the world. Furthermore, all four of its sides align precisely with the four cardinal points of the compass, although this instrument was invented thousands of years after the construction of the pyramid. And is it only a mere coincidence that the construction of pyramids many similar to that of Giza were evolving exactly on the other side of the world, on the Mesoamerican continent?

There are pyramids on remote islands in the Pacific, in India, in Mexico. It is a building present all over the world and archaeologists are not able to explain well why dissimilar cultures, separated by huge oceans, build the same structures in the same way. 

The Mystery of Teotihuacan

In central Mexico there is an ancient city that dates back more than two thousand years. Its name, Teotihuacan, literally means “city of the gods”. At the center of the city stands the Pyramid of the Sun. Incredibly, the perimeter of the Pyramid of the Sun is the same as the Pyramid of Giza.

A structural coincidence? Or could it have been inspired by the same architects in both cases? There are a couple of theories about it. The first is that perhaps the same thing has been taught to all cultures by an extraterrestrial species. The second is that there were some ancient travelers on this planet who traveled from one region to another over enormous distances. And then there are the skeptics who say that, from the archaeological point of view, it was the best way to build them, they just knew! In Teotihuacan there are the gigantic Pyramid of the Sun and the gigantic Pyramid of the Moon.

According to the legends, they were built by the gods, who were giants at the end of one of the world’s destruction. Civilizations like the Aztec, the Mayan and the Hopi Indians of northern Arizona believe that the world has been destroyed four times in the past, each time by a different element like water, fire, ice.

Each time, humanity rebuilt the world and Teotihuacan was built at the beginning of one of these four worlds.

Easter Island Moai

Easter island

A remote area of the Pacific Ocean is located one of the most isolated places in the world: Easter Island. Here, more than 800 stone guardians, called Moai, stand guard on the island’s coastline. Are these sculptures of the ancient primitives, or disturbing portraits of visitors alien to thousands of years ago? Whatever their purpose, they were made to last for thousands of years. They are built with blocks of stone weighing several tons, yet they were primitive people’s who made them without good reason. One aspect to think about when considering what an ancient civilization could create is the ability to write down construction methods. If we had a written test of how they managed to build these structures, we would certainly believe it. In Egypt, for example, we have many writings and drawings showing the construction of the pyramids. On Easter Island, however, we do not have written evidence about their statues and this makes us doubt their actual abilities. About 4,800 kilometers away, in the Republic of Bolivia, there are incredibly similar stone works similar to the Easter Island statues. Teotihuacan is indeed so old that it escapes modern dating techniques. It is estimated that it is more than 17,000 years old and is perhaps the oldest city in the world. In some ways, Teotihuacan’s sculptures were built in the same style and with the same enigmatic expressions of distant cousins on Easter Island.

The perfect incisions of Puma Punku

Puma Punku

But while tourists flock to the ruins of Tiahuanaco, an ancient, and perhaps more mysterious, site is only a few hundred meters away. Of relatively little interest to the majority of visitors, Puma Punku is a site with stone ruins that excite and stimulate the imagination of the theorists of the Ancient Astronauts, and is considered the most likely solution to the enormous puzzle of this fascinating theory. If the pyramids of Giza are an incredible achievement, in comparison to Puma Punku the pyramids are child’s play. There is no logic to Puma Punku, because there are megalithic structures lying on the whole site, as if they had been torn apart by some terrible catastrophe. The blocks are cut with such precision that in the past they fit perfectly, like the weave of an elaborate puzzle. Also, if the nearest quarry was more than 16 kilometers away, how did these colossal stones, some hundreds of tons, get to the site? We are talking about a place that is 4 thousand meters above sea level. This means that there are no trees to use as rollers. Only grass and bushes grow. Puma Punku is the most spectacular site of antiquity, because what is there is so inexplicable, so impossible to create, that the question remains: how was all this built and for what purpose? Traditional archaeologists say that Puma Punku was built by the Aymara Indians. Now everyone agrees that to create something like the one you find in Puma Punku you have to write, design, you must have an idea of where each piece goes and how it is composed together at the end. But there is one thing that even the traditional archaeologists agree: the Aymara did not have the writing! So how could they build this without projects? One of the reasons why the theorists of the Ancient Astronauts are so attracted to sites like Teotihuacan and Puma Punku is the quality of stone processing and the immense dimensions of the blocks, so extraordinary and perfect that they suggest machining, the use of tools mechanics to cut and engrave them. One of the platforms weighs more than 800 tons and they are all very smooth. Some other megalithic pits have only a few millimeters of grooves, impossible to do with stone-age chisels, so there must be another type of technology behind it. The lines cut into these stones are perfectly straight and have the same exact depth from one end to the other. All too perfect to imagine primitive men who work the stone with such precision using only chisels. Some university researchers visiting Puma Punku with their measuring instruments were literally shocked. In their reports they write that it is impossible to reconstruct Puma Punku, even with the modern technologies in our possession. All these clues show a great anomaly: on the one hand, these ancient peoples are considered very primitive, just out of the stone age, yet they create things that we would not be able to do today, or that we would do with extreme difficulty, that is produce these giant stone blocks, perfectly matching other interlocking blocks.

The truth is that the ancient peoples of our planet saw incredible things, were witnesses of bizarre and incomprehensible events. But the evidence of those events has disappeared. For some reason they vanished, but those peoples left us incredible objects before which we ask ourselves: how the hell did they build them”?
