Scientists are sure that extraterrestrial contacts with terrestrial civilizations took place millions of years ago

(ORDO NEWS) — A widely accepted hypothesis in alternate history is that before and after the Great Flood, there was a typical humanoid race that formed civilization on Earth. Such beings are referred to in the Old Testament of the Bible as “fallen angels”, and in Sumerian literature they are called “anunnaki”.

Looking into the past, a group of reputable scientists published a study that studied the intelligent and industrial civilization that could have existed on planet Earth millions of years ago.

It would take only 10,000 years for humans to disappear from the planet, which is very short compared to the age of the Earth. If such a civilization existed, the traces would not be so obvious – given that over 4 billion years of the Earth’s existence is a sufficiently wide range for the evolution (and destruction) of intelligent life.

A peer-reviewed scientific paper published in the International Journal of Astrobiology is titled “The Silurian Hypothesis: Can Industrial Civilization Be Detected in the Geological Record?”

The title of the article is a reference to the reptilian humanoids known as the Silurians, who in the cult science fiction series were once part of an advanced civilization on Earth during the Silurian period (about 400 million years ago).

The study grew out of a visit by physicist Adam Frank to NASA‘s Goddard Institute for a talk with scientist Gavin Schmidt. Frank was interested in whether any industrial civilization that arose on another planet could, through its activities, cause its own version of a climate shift.

But Schmidt asked a different question: “How do you know that we are the only case when a civilization has existed on our planet?”

This idea seems incredible to the scientist, but it is not, at least not something that does not deserve research and that can be excluded from the very beginning. Instead of discussing aliens, scientists got involved in a discussion about the possible remnants of an ancient civilization.

The geological record does not go beyond the so-called Quaternary period of 2.6 million years ago. For example, the oldest large-scale site of the ancient surface is in the Negev Desert.

It is 1.8 million years old and the older surfaces are mostly visible in cross section through what appears to be a cliff or rock cuts. If you go back much further than the Quaternary period, then everything will be turned upside down and crushed into dust.

At this stage, it is worth noting that the proportion of life that is fossilized is extremely small and “varies greatly with time, habitat, and the degree of soft tissue versus hard shells or bones… There are only a few dinosaurs that have ever lived.” thousands of nearly complete specimens, or equivalently, just a few individual animals from thousands of taxa per 100,000 years.”

It is likely, for example, that if Homo sapiens were to disappear today, there would be no fossil remains of our species in a few million years.

Our industrial civilization lasted only 300 years, and may not last much longer. It is therefore implausible that a civilizational explosion could have occurred during a similar period of time in the past, and 500 years or so, compared to billions of years, is nothing.

Technical items and fossils are unreliable. However, Frank and Schmidt noted that there is something that can trace the passage of hundreds of millions of years: “physico-chemical traces of previous industrial civilizations,” that is, anomalous changes in chemicals found in the geological record that indicate that something strange happened.

For example, if we look at our own era, the Anthropocene, we see that rare earths are used in computers, huge amounts of fertilizers are used in agriculture, radiation from nuclear reactors and bomb tests, plastics flooding the ocean, and a huge increase in carbon in the atmosphere. All this can be seen by scientists when they study the chemistry of past epochs.

And in the geological record there are certain “riddles” that can be candidates for the “Silurian hypothesis”. For example, during the Eocene (56-34 million years ago) a series of “hyperthermal events” occurred, characterized by “significant negative excursions of carbon isotopes, warming and a relatively high rate of sedimentation caused by an increase in the supply of terrigenous substances”, as well as arctic conditions demonstrating ” signs of warming, decreasing salinity and increasing anoxia”, which have been collectively called ELMOs: “Eocene layers of mysterious origin”.

Of course, scientists should analyze these cases to determine whether these anomalies were caused by natural phenomena, which is obviously the most likely hypothesis. On the other hand, this work may serve to apply models to other planets where civilizations may have existed in distant times, such as in the case of Mars, which at some point in its existence had a lot of water.

In 2014, NASA published a book titled “Archaeology, Anthropology and Interstellar Space” which examines extraterrestrial intervention in human history. It notes the possibility that some of the rock art on Earth may be of extraterrestrial origin. The book was edited by Douglas Vakoch, director of the Search for Extraterrestrial Intelligence (SETI).

Douglas Vakoch, for his part, talks about the difficulties that may arise as a result of the first contact with an extraterrestrial civilization.

“If a radio signal is detected in a modern SETI experiment, we may well know that another mind exists, but not know what it is saying. Any fast, information-rich fluctuations encoded in radio signals can be smoothed out by collecting weak signals for a long period of time, which increases the chances of detecting these signals, but at the same time their content is lost.

Even if we find a civilization orbiting one of our closest stellar neighbors, its signals will travel trillions of miles and reach Earth after years of travel.”

To go beyond the mere discovery of such intelligence and have a real chance of comprehending it, we can learn a lot from the lessons learned by researchers who have faced similar problems on Earth.

“Like archaeologists who reconstruct distant civilizations from fragmentary evidence, SETI researchers must “will restore distant civilizations separated from us by vast spaces as well as time.

And like anthropologists who try to understand other cultures despite differences in language and social customs, when trying to decipher and interpret extraterrestrial messages, we will have to comprehend a way of thinking of a radically different kind”.

Vakoch writes about the desirability of establishing symbolic/linguistic communication with an ET. It is useful to look at some of the parallels in human existence that pose problems for us today. One of them is “rock art”, which are patterns or shapes carved into the rock thousands of years ago.

Such ancient rock art can be found in many countries, with an example (as shown above) being at Doddington Moor, Northumbria, England. We can’t say much about what these patterns mean, why they were carved into the rocks, or who created them.

By all indications, they could have been made by aliens. Until we find a readable exegesis written at the time they were made, we will never be able to say with certainty what these patterns mean.
