From time to time, people come across such finds that do not fit into our generally accepted ideas not only about the history of the development of human civilization, but the entire planet.
Let's consider some of them
A coin-like object was recovered from a drilled hole at a depth of about 38 meters. It happened near Lawn Ridge in Illinois, USA.
According to official geological estimates, the coin was recovered from a layer of rock between 200,000 and 400,000 years old.
Who could have left her when, as is commonly believed, civilized man had not yet appeared on Earth?
In 1913, Professor Hans Reck of the University of Berlin was excavating the Olduvai Gorge in Tanzania.

There he found a skeleton similar to that of a modern man, a mystery to this day.
This is a skull from a find that was cemented in a rock dating back over a million years.
How did a modern man end up there then?
The age of the "Willendorf Venus", found in Europe, is estimated at 30 thousand years.
Who created or left this statuette about 20 thousand years before the first human civilization appeared?
A small human figurine, skillfully sculpted from clay, was found in 1889 in Nampa, Idaho.
It was recovered from a well at a depth of 100 meters and, according to geological estimates, it should be about 2 million years old.
At that time, people on the planet simply should not have been yet - who then created or left this figure?
In a report by the British Association for the Advanced of Science in 1881, a shell was found that was engraved with a conventional, but undoubtedly human face.
This shell was found in layered sediments at a place called Red Crag.
Those deposits are estimated to be between 2 and 2.5 million years old.
In 1877, Mr. JH Neale was the managing director of a company called the Montezuma Tunnel company and was involved in a lava tunnel near Table Mountain in California.
A vessel with a pestle was found at a distance of about 500 meters from the entrance to the tunnel, that is, at a depth of about 100 meters under a stream of solidified lava.
It was impossible for these items to get there after the lava flow formed 33 to 55 million years ago.
Y. Druet and H. Salfari of France announced in 1968 the discovery of semi-oval metal pipes of the same shape, but different sizes, in Cretaceous Cretaceous deposits dating back over 65 million years, found in the Saint-Jean de Livet quarry.
Where did these pipes appear there 65 million years before the appearance of man?
On October 8, 1922, the American Weekly section of the New York Sunday American published an article entitled The Fossilized Sole Mystery, signed by Dr. WH Ballou.
He wrote that some time ago, when he was searching for fossils in the state of Nevada, John T. Reid, a famous mine engineer and geologist, saw an imprint in a stone that resembled a footprint of a human foot.
A closer look at that print revealed that it was a footprint in a shoe.
There was no print of the front of the shoe, but two thirds of it survived.
Traces of two stitches of threads stitched into the sole were clearly visible, as well as other features of worn shoes.
Analysis by an analytical chemist at the Rockefeller Institute showed beyond doubt that it was a genuine human shoe print.
Magnified 20x micrographs showed the finest details of the twists and turns of the filaments, proving that they were made by human hands, not just a coincidence.
This stone footprint is estimated to be 213 to 248 million years old, long before the dinosaurs …
On June 22, 1844, the London Times reported that a few days ago, workers in a quarry nearby, a place called Tweed, found a gold chain inside the stone. The find was made at a depth of 8 feet.
British geologist Dr. AW Medd wrote in 1985 that the stone was between 320 and 360 million years old.
The Illinois newspaper The Morrisonville Times wrote on June 11, 1891, that a gold chain was found inside a lump of coal. The age of that coal is estimated at 260 - 320 million years.
On April 2, 1897, the Daily News of Omaha, Nebraska, ran an article entitled "Carved Stones Buried in a Mine," which described an object found in a mine near Webster, Iowa.
There, at a depth of 130 feet, a dark gray stone slab was found, two feet long, one foot wide and 10 centimeters thick. On the surface of this slab of very hard stone there were lines representing perfect rhombuses.
In the center of each such rhombus was an image of an old man's face with an unusual depression on his forehead, and all these images were exactly the same.
Except for two, all the other faces looked to the right.
The age of the coal seams where that slab was found is estimated to be between 260 and 320 million years old.
On November 27, 1948, Frank J. Kenwood of Arkansas made a statement that when he was working at a power plant in Oklahoma in 1912, he found a jellied pot inside a large lump of coal he had smashed.
Another worker also saw this happen.
When Frank traced where the coal came from, it turned out that it was brought from a mine in Oklahoma, whose coal is estimated to be 312 million years old.
WW McCormick from Texas recounted the memories of his grandfather, Atlas Almon Mathis, who worked at Coal Mine 5 near Heavener, Oklahoma, which was about 2 miles deep.
Once, after another explosion of the rock, several concrete blocks were found among its fragments. They were 30 - centimeter cubes, which were so polished that they could serve as mirrors.
A little later, the rock in this place collapsed, and a solid wall of these polished blocks became visible.
A piece of this wall at least 150 meters long was visible.
The coal in this mine was at least 286 million years old.
As soon as this happened, senior company officials immediately removed the people from the mine and forbade them to talk about what they saw.
Mathis also said that miners from another mine told him about the discovery of a large piece of silver in the shape of a barrel, which was found in coal seams from 280 to 320 million years old.
In this case, it is obvious that if this is a reliable find that the found fragment of the wall was part of some large structure that belonged either to an ancient earthly civilization, or was a fragment of a base of aliens or time travelers - one can only fantasize about this …
In 1868, James Parsons and his two sons discovered in a coal mine in Ohio a surface exposed by a collapse of a coal seam, on which several lines of hieroglyphs were engraved.
The age of the coal in that mine was estimated at 260 million years.
On June 5, 1852, Scientific American published an article that after the explosion of a huge rock in Dorchester, a metal vessel was found among the wreckage.
It was about 11 centimeters high, about 16 centimeters wide and about 3 millimeters thick.
The color of the material resembled zinc or an alloy with most of the silver. On the sides of the vessel were six images of a flower or bouquet, beautifully inlaid with pure silver, and around the bottom was an image similar to a vine, also made of silver.
The rock inside which this vessel was located was at a depth of 5 meters, and its age is estimated at more than 600 million years.
The famous metal spheres found in South Africa and pictured below are estimated to be 2.8 billion years old.
Hundreds of such balls have been discovered, which are of two types: some balls consist of a solid bluish metal, while others are hollow inside, with a porous material in the center.
These balls, with three parallel grooves engraved along the equator, are undoubtedly of artificial origin.
In 1830, in a marble quarry near Philadelphia, USA, raised letter-like marks were found inside a solid piece of marble at a depth of 60 to 70 feet.
This was reported in the American journal Science, vol. 19, 1831.
This is a description of only a part of such finds around the world, including Russia.
So who belonged to these artifacts, found under circumstances that indicate their age in many thousands or millions of years?
People who have traveled in the past, if this is possible in principle?
Representatives of unknown ancient civilizations that once existed on our planet?
Or visitors from other worlds who have done this more than once?
Most likely, we will not know the answers to these questions soon, or never at all …
