4. Metal Tools 65 Million Years Ago It is impossible for humans to have existed 65 million years ago. There were no humans capable of making metal tools during that period. What is the correct scientific explanation for a 65-million-year-old piece of chalk (a loose calcite powder) excavated in France that contains a semi-oval metal tube? In 1885, a lump of coal split apart and was found to contain a metal cube. , looks clearly a smart handmade product. In 1912, workers at a power plant split a large piece of coal and found an iron kettle falling out of it! In addition, archaeologists also found a fingernail deeply embedded in the sandstone blocking layer of the Mesozoic Era, and there are many more bizarre things. Events await this step. 5. Fossils that cannot exist Fossils, this concept is learned in school, appear in rocks and were formed thousands of years ago. However, there are still a certain number of fossils that cannot be understood through geology or history. For example: a fossil of a human finger was found in limestone in the Canadian Arctic, and its history can be traced back to 100-110 million years ago. In addition, a human footprint fossil was discovered in the shale sedimentary layer in the Delta region of Utah, USA. It may have been left by worn sandals, and its history can be traced back to 300-600 million years ago. 6. "Eula Linda's Secretary" "Eula Linda's Secretary" is a controversial Frisian (indigenous or resident of Frisian Island or the Dutch province of Friesland) manuscript, which includes history, mythology and religious themes, which first attracted attention in the 19th century. The book covers doom, nationalism, matriarchy and mythology. Some of the contents are closely related to reality, and the book seems to have a magical power to predict future changes. 7. Giant stone balls in Costa Rica In the 1930s, when construction workers were opening a road for banana plantations in the dense jungle of Costa Rica, they cut down and burned the dense jungle. However, to their surprise, ten objects suddenly appeared while opening the road. Several mysterious spheres, their shapes are very close to the shape of spheres. They come in a wide range of sizes, from ping pong balls to an astonishing 8 feet in diameter and weighing 16 tons! Although the largest stone balls are obviously man-made, what is puzzling is that these perfect boulders Who made the ball, and for what purpose? The most puzzling thing is how people made such precise spherical stone balls? 8. Ica Stone Since the 1930s, Peruvian anthropologist Javier Ca Borrella's father discovered hundreds of burial ritual stones in ancient Inca tombs. Cabrera inherited his father's work and collected more than 1,100 andesite stones, dating back to 500-1,500 years ago, all of which were collected as Ica stones. What is very strange is that there are many patterns etched on the Ica stone, many of which are sexual patterns, which is common for the Inca culture. Some of the images depict operations like heart removal and brain transplants. Amazingly, some of the designs clearly depict dinosaurs, brontosaurus, triceratops, stegosaurus, and pterosaurs. However, skeptics believe that these ika stone designs are just a farce and their authenticity has not been proven. , and was not refuted. 9. Dulipa Mysterious Stone In 1938, an archaeological expedition led by Qi Futai discovered amazing ancient culture in some caves in the Bayanhara Mountains in Tibet, China. Hundreds of stone plates were buried in the caves. Measuring 9 inches in diameter, each piece is etched with a circumference at its center and a spiral groove etched out. It appears to be 10,000-12,000 years old. The spiral grooves spin like small hieroglyphics telling the bizarre story of a spaceship from a distant world that crash-landed on the mountain range. The intelligent beings piloting the UFO-like craft are known to locals as Dropa, and the bodies of their descendants may still be preserved in the cave. 10. Ancient grooved metal balls in South Africa. In the past ten years, South African miners have unearthed some mysterious metal balls. Their origins are still unclear. These metal balls are roughly 1 inch in diameter. Three parallel lines are etched on the circumference of the metal balls. Grooves, two types of metal balls have been discovered: one contains solid blue metal balls with white spots; the other is hollow and filled with a spongy white substance.The manufacture and use of the metal balls are unknown. 11. The Mystery of the Loch Ness Monster The Loch Ness Monster is one of the most mysterious and fascinating mysteries on earth. Loch Ness is located in the Grand Canyon in the northern part of the Scottish Plateau, England. The lake is 39 kilometers long and 2.4 kilometers wide. The area is not large, but deep. The average depth is 200 meters, and the deepest is 293 meters. The lake never freezes all year round, with steep banks and dense woods. There is a river at the northern end of the Hubei that connects with the North Sea. The earliest record of a water monster can be traced back to 565 AD. The Irish missionary St. Columb and his servant were swimming in the lake. The water monster suddenly attacked the servant. Thanks to the priest's timely rescue, the servant swam back to the shore and saved his life. Since then, in more than ten centuries, there have been more than 10,000 reports about the appearance of water monsters. But people at that time did not miss this, thinking it was just an ancient legend or nonsense. Until April 1934, London doctor Wilson was passing through Loch Ness and happened to find a water monster swimming in the lake. Wilson quickly took a photo of the water monster with his camera. Although the photo was not very clear, it still clearly showed the characteristics of the water monster: a long neck and a small head, which did not look like any kind of aquatic animal at all. , and very similar to the giant reptile plesiosaur that became extinct more than 70 million years ago. The plesiosaur was a giant aquatic reptile that lived from more than 100 million to more than 70 million years ago. It was also a distant relative of the dinosaurs. It has a slender neck, oval body and long tail, with sharp teeth in its mouth. It feeds on fish and is the overlord of the Mesozoic sea. If the Loch Ness Monster is really a snake, it is undoubtedly an extremely precious surviving prehistoric animal, and this discovery will also occupy an important position in zoology. Therefore, after this photo was published, it quickly caused a worldwide sensation. With the "dinosaur craze" of the 20th century, people began to connect the water monster and the plesiosaur that might still be alive, and paid great attention to this. On April 23, 1960, British aeronautical engineer Dingsted took a film of more than fifty feet in Loch Ness. Although the film was rough, it was still obvious when it was shown that a giant black creature with a long neck was swimming across Loch Ness. . Some scientists who originally had a negative attitude towards this changed their views after watching the film. The Royal Air Force's Joint Air Reconnaissance Intelligence Center analyzed Dinsted's video and concluded that "that thing is probably a living thing." In the 1970s, scientists began to use advanced instruments and equipment to search for water monsters on a large scale. In August 1972, Boston, USA, used underwater cameras and sonar to take some photos in Loch Ness. One of them showed a two-meter-long diamond-shaped flipper attached to a huge creature. physically. At the same time, sonar instruments also detected large objects moving in the lake. In June 1975, the hospital sent an expedition team to Loch Ness again and took more photos. Two of them are of particular interest: one shows a large body with a long neck, and may also show the object's two stubby flippers. It is estimated from the photos that the creature is 6.5 meters long, of which the forehead is 2.7 meters long. It does look like a plesiosaur. Another photo captured the head of the water monster. After being enlarged by a computer, you can see the short tentacles and wide mouth of the water monster. The official conclusion was that "there is indeed a large unknown aquatic animal in Loch Ness." The discoveries in 1972 and 1975 caused a sensation, making people feel that it was imminent to uncover the mystery of the water monster or to capture a live plesiosaur. After that, Britain and the United States jointly organized a large-scale expedition team and sent 24 research ships to form a long snake formation and sail across Loch Ness like a net in an attempt to capture the monster in one fell swoop. But unfortunately, apart from recording some more sonar data, nothing was found. Due to the failure of the hunt for the water monster, negative views became popular again. A retired electronic engineer wrote an article in the British "New Scientist" magazine: The Loch Ness monster is not an animal, but an ancient pine tree. He said that more than 10,000 years ago, there were many pine trees growing near Loch Ness. At the end of the ice age, "the lake water rose and many pine trees sank to the bottom of the lake. Due to the pressure of the water, the resin in the trunks was discharged to the surface, and the resulting gas could not be discharged. So these pine trees sometimes floated to the surface, but on the water After releasing some gas, it will sink to the bottom of the water. To people from a distance, it looks like the head, neck and body of a water monster.

” But this view cannot convince those who claim to have witnessed the water monster with their own eyes. And in the late 1970s, some people took photos of the water monster several times. So, why can’t people capture the water monster so far? This starts from Nice Talking about the special geological structure, it turns out that the water of Loch Ness contains a lot of peat, which makes the lake very turbid, and the bottom of the lake is less than three or four feet deep. The topography of the lake bottom is complex, with maze-like deep valleys and ravines everywhere. It is also easy for huge aquatic animals to stay quietly and avoid detection by electronic instruments. There are many fish in the lake, so water monsters do not need to go out to look for food. The lake is connected to the sea, so water monsters have easy access. Therefore, if you want to capture water monsters, Easier said than done. But as long as the water monster is not actually found, the mystery remains unsolved. Until now, no one can draw conclusions about the existence of the water monster. British writer Zister said: "There is evidence of the crime of many suspects." , there was less evidence than the existence of the Loch Ness Monster, so he was hanged. "This is a humorous and clever evaluation of the mystery of water monsters in ancient and modern times. 12. The Mystery of Qin Shihuang's Terracotta Warriors and Horses On March 1, 1994, the world-famous "Eighth Wonder of the World" - Qin Shihuang's Terracotta Warriors and Horses Pit No. 2 was officially opened Excavation started. This is one of the great archaeological discoveries of this century. Copper spears, copper crossbows, copper arrowheads, broken swords, etc. were unearthed in the No. 2 figurine pit. A batch of bronze swords with a length of 86 centimeters were also discovered. There are eight edges on the sword. Archaeologists used vernier calipers to measure and found that the error of these eight edges was less than a hair. This is the internal structure of the 19 bronze swords that have been unearthed. The sword is dense, the blade is bright and smooth, the blade is finely polished, and the textures come and go without interlacing. They have been sleeping under the loess for more than 2,000 years. When they were unearthed, they were as bright as new and extremely sharp. After testing, scientific researchers found that there was a layer of 10 on the surface of the sword. Micron-thick chromium salt compound. This discovery immediately caused a sensation in the world, because this chromium salt oxidation treatment method is an advanced process that only appeared in modern times. Germany invented and patented it in 1937 and the United States in 1950. When passing through the first hole in Pit No. 1, archaeologists found that a bronze sword was bent by a pottery figurine weighing 150 kilograms. The bend was more than 45 degrees. When people removed the pottery figurine, they were surprised. A miracle happened: the narrow and thin bronze sword rebounded straight in an instant and recovered naturally. The "morphological memory alloy" dreamed by contemporary metallurgists actually appeared in ancient tombs more than 2,000 years ago. Regarding the method of chromium salt oxidation treatment, it was by no means an invention of the Qin Shihuang era. As early as the Spring and Autumn Period and the Warring States Period, the Chinese had mastered this advanced technology. , performed the last scene of the Spring and Autumn Hegemony in history. As the years passed, this thrilling war fell silently into the long scrolls of history, and the busy descendants almost forgot about it. However, an archaeological team was digging. When visiting the ancient tombs of the Spring and Autumn Period, they unexpectedly discovered a long sword covered with mud. A line of ancient seal on the sword - "King Gou Jian of Yue's own sword" jumped into people's eyes. This major archaeological discovery immediately caused a sensation across the country. However, The more sensational news comes from the scientific research report on the ancient sword. What first caught the attention of researchers is: why has this ancient sword not rusted after being buried underground for more than two thousand years? ? Through further research, it was found that the reason why the "Yue Wang Goujian Sword" has remained rustless for thousands of years is that the sword is coated with a layer of metal containing chromium. As we all know, chromium is an extremely corrosion-resistant rare metal, and chromium is contained in earth rocks. The amount is very low, and it is very difficult to extract. Furthermore, chromium is a metal that can withstand high temperatures. Its melting point is about 4000°C. There were so many secrets in Chinese civilization. Who can imagine the science in the 1950s? The invention actually appeared more than 200 years ago? Who can imagine that the sword wielded by Qin Shihuang's soldiers turned out to be a masterpiece that has not yet been invented by modern science? The question is, what attitude should we take after the discovery? Explain this extraordinary phenomenon of premature technological maturity? We really don't want to see some people explain it by "accidental", it should have a more specific explanation.

If the above facts are true (at least the chromium salt oxidation treatment is not false), then we will ask: What is the origin of their technology? 13. The UFO Mystery 1. The Defense Intelligence Agency is a secret intelligence agency within the Pentagon of the United States. It is responsible for coordinating the intelligence activities of the U.S. Army, Navy and Air Force. The Defense Intelligence Agency works not only for the Pentagon, but also for the CIA. In the late 1970s, the U.S. UFO research organization Citizens Against the Cover-up of UFOs submitted a file request to the Defense Intelligence Agency under the Freedom of Information Act. They hope to obtain from the Defense Intelligence Agency the files it has on UFO incidents. Initially, like other U.S. government agencies, the DIA denied any involvement in UFO research. However, in the end, it had to release three eye-catching UFO files. The contents of the three secret files first disclosed by the Defense Intelligence Agency are the blueprints for typical American Steven Spielberg movies. One of the three files involves a report on the discovery of UFOs by the Iranian Air Force on September 19, 1976. 1) At around 12:30 pm on September 19, 1976, the Iranian National Air Force Command received four calls from residents of the Misheran area near the capital Tehran. Several residents said on the phone that they had discovered very strange flying objects in the local sky. Some people say that the UFOs are shaped like birds. Some people describe them as helicopters with bright lights. He (referring to the person who drafted the report on the Iranian National Air Force Base) explained to the residents that the so-called strange flying objects might be stars. After a phone call with the air force airport in Mehrabad, he decided to go and see those things for himself immediately. 2) At about 1:30 a.m. on the 19th of this month, this F? interceptor was located in the air about 40 nautical miles north of Tehran. Because the light emitted by this UFO is so intense, it can be seen clearly from a distance of 70 nautical miles. When the plane approached the UFO to 20 nautical miles, the alarm system and monitoring equipment on the plane suddenly failed. At this time, the pilot had to return to Sarooq base. When the pilot just turned the plane's head, the functions of the monitoring equipment and signaling system in the aircraft cabin were not only restored at once, but the danger of sudden engine stalling disappeared. At 1:40, the second fighter took off. When the plane was in the air, 27 nautical miles north of Tehran and at an altitude of 150 nautical miles, traces of the UFO began to appear on the plane's radar screen. 3) The size of this UFO is approximately the same size as a Boeing 707 (tanker). Because the light emitted by this UFO is so intense, it is difficult to accurately judge its size. This UFO emits a strong beam of light that changes in sequence from blue, green, red, and orange while flying vertically toward the ground. Because the wave frequency of these light beams appears to be very high, they can all be observed at the same time. When the two F? interceptors tracked the UFO into the sky south of Tehran, another shining flying object suddenly flew out of its body. This flying object that just flew out is about half or even one-third the size of the full moon in the sky. Then, this small UFO, which had just separated from its mother body, rushed towards the two F? interceptors at an extremely high speed. One of the pilots tried to launch a Type 9-type air interception rocket at it, but at this time the rocket launch control system in the cabin failed and the intercom had no signal. At this moment, the pilot quickly leaned up and pulled the plane in a high arc, trying to get rid of the UFO. He followed up with another dive. However, the original UFO followed and kept a distance of three to four nautical miles from it for a period of time. Just as the pilot was pitching up and diving in an attempt to escape tracking, the second small UFO that separated from the parent UFO remained within the arc drawn by the aircraft in the sky. After a while, the small UFO flew towards the mother body and merged into one.

4) Not long after the small UFO merged with the parent body, another UFO suddenly flew from the other side of the original parent UFO, and it flew vertically towards the ground. 5) At dawn the next day, a helicopter carried the two interceptor pilots and took them to the location where the small UFO most likely landed last night. There, except for a dry riverbed that was suspected to be the landing site of the UFO, they found nothing else related to it. As the party reached the western edge of the strip, they stumbled upon valuable information. There was a family living there. The family members said that they heard a loud noise outside at midnight last night, and along with the noise, there was a lightning-like bright light outside the house. As a result, people began to test this area and the two aircraft to see if they had nuclear radiation. If any results come out in the future, we (here, the National Defense Intelligence Agency) will report them promptly. The file lists a long list of U.S. government and military agencies at the beginning. It is easy to see that the UFO incident in Iran has attracted great attention from the top leadership of the U.S. government. . 14. Ghost Mystery In May 2004, a group of urban adventure enthusiasts sneaked into an abandoned naval dockyard in South Plymouth, England. In the cabin, there was an ancient lampshade, a dirty mattress, an overturned TV, and even several pieces collapsed. The wooden beams are the result of their exploration. Suddenly someone discovered an unexpected discovery: he heard a woman's sobs coming from deep in the cabin... 15. The mystery of the crash of a Korean passenger plane. A Korean Air Boeing 747 passenger plane flying from Seoul to Guam crashed in 1997 local time. It crashed near Guam International Airport in the early morning of August 6, killing more than 200 people. It was raining heavily and the weather was bad. When the plane was flying about 5 kilometers away from Guam International Airport, it suddenly disappeared from the radar screen and lost contact with the ground control tower. According to eyewitnesses, the plane crashed into the dense forest near the airport with a ball of fire and an explosion was heard. After 17 hours of intense work, U.S. rescuers recovered about 70 bodies of victims from the wreckage of the South Korean passenger plane that crashed in Guam and the accident site; Korean Air said that 29 of the 254 people on board survived, including 4 Cabin crew. The National Transportation Safety Board sent a special investigation team to the scene to investigate the cause of the accident. Two "black boxes" from the crashed airliner have also been found and sent to Washington for analysis. Officials from South Korea and the United States disagree on the cause of the Korean Air plane crash. South Korea emphasized that the navigation device at Guam Airport was malfunctioning at the time, and the personnel on duty at the airport control tower were not employees of the FAA. In addition, the weather was abnormal at the time, which eventually led to the plane crash. The United States believes that the failure of the navigation device should not affect the normal landing of the aircraft, and questions why South Korea replaced the Airbus flight that normally flies on this route with a Boeing 747 charter flight that has been flying for 13 years. The Boeing Aircraft Manufacturing Company says its products have an accident rate of only 1.78 per million. On August 10, U.S. federal investigators said that the investigation found that when the South Korean large passenger plane crashed, the computer software of the Guam International Airport's radar system was malfunctioning and failed to issue an alert in time when the plane approached the ground. Under normal circumstances, when an aircraft flies close to the ground, the airport radar system will sound an alarm, and the ground commander will promptly remind the pilot. However, the investigation found that due to a software problem, the radar did not detect the South Korean plane approaching the ground, so the pilots did not receive a warning from the ground control tower before the plane crashed. Officials from the U.S. National Transportation Safety Board who are responsible for investigating the crash believe that problems with this radar system cannot be said to be the cause of the plane crash, but can only be said to be a lack of preventive measures. There are many factors that may contribute to a plane crash. In addition, the navigation system that guided the plane to land at Guam Airport had been out of use for a long time before the plane crash; it was raining heavily when the plane approached Guam Airport. These are all possible factors for investigators to study the plane accident.

16. The Mystery of Spontaneous Human Combustion The so-called spontaneous combustion of human body means that a person's body catches fire on its own without contact with external fire. This incredible phenomenon was first seen in medical reports in the 17th century. By the 20th century, more than 200 incidents had occurred in Japan. In the early 19th century, some believed that this scourge only befell women who drank too much, were obese, and lived alone. However, many subsequent cases proved that the victims were roughly equal in number to men and women, ranging in age from infants to 114 years old, and in many cases they burned for no reason in places without fire sources. One of the best early evidences of spontaneous human combustion was recorded by Bartholin in 1673. That time, a poor woman in Paris spontaneously ignited and died after going home and going to bed one night. The next morning it was discovered that only her head and fingers remained, while the rest of her body was burned to ashes. Based on this spontaneous combustion incident, the Frenchman Reier published the first paper on human spontaneous combustion in 1800. In a short period of time, France, the United Kingdom, and Italy all had sensational cases of spontaneous human combustion. The most recent and influential one was on December 27, 1976, when the Arria Herald reported that six members of a family of seven in Lagos City were burned to death, which became the most difficult mystery to explain at the time. The report said: "On-site investigation showed that all the objects in the wooden house were intact, and even the bedding was neatly placed on the bed. However, judging from the severity of the burned victims, everything in the house should be completely gone." Although many police, fire brigade, arson case experts, and pathologists have presented a lot of evidence, there is currently no reasonable physiological argument to prove why the human body spontaneously combusts or even turns to ashes. Conventionally speaking, human organs, tissues and bones can only be burned to ashes in a high-pressure crematorium at 900-1000 degrees Celsius, and burning on their own is indeed incredible. In addition, some people have proposed other factors for spontaneous combustion, such as meteors, lightning, atomic explosions in the body, laser beams, geomagnetic energy, etc. However, there is no explanation under what conditions these can work to form spontaneous combustion. In short, the phenomenon of spontaneous combustion in the human body is still a mystery. 17. The mystery of the crystal head. In 1926, a crystal carving was discovered at the site of the Mayan civilization in Honduras. Take off the part of the lower jaw and touch a certain tree from the lower part, and the eyes will light up. Although it is an anatomically correct model of the human skull, the delicate way the teeth fit together is truly impressive. There is also a surprising production method: some of the teeth are obviously cut using rotating tools. To allow this exquisite handicraft to be combined up and down, it would have been impossible for a rotating tool to exist at the technical level at the time, making the mystery of the crystal skull even more puzzling. There were no crystal deposits in the area where the Mayans lived. Some experts believe it was made by the Aztecs and could not predate the colonial period because its teeth show signs of mechanical work, according to Doland, who identified the skull. The skull has two perforations (perforations that were already there when Anna claimed she "discovered" the skull), presumably used to secure the skull during display, and the perforations were apparently drilled with modern mechanical tools. In the 1960s and 1970s, Anna had it submitted to the crystallographic laboratories of Doland and Hewlett-Packard for identification, and concluded that it was carved from a single piece of crystal. Dorland told Nickell that he did not find the physical properties of the Crystal Skull to be any different from naturally occurring quartz crystals, and that its crystals were "so close to those found in the huge crystal mines of Calaveras County, California, that I It is speculated that the original crystal block came from there..." Norman Hammond, an expert on Mayan culture, believes that this crystal skull is very realistic in anatomy and is more like a product after the West entered the scientific era: "It is most likely a memorial to the dead from the 16th to 18th centuries. If the idea that it originated from the Renaissance is not impossible, then given the size of the crystal block it is made of, we cannot rule out the possibility that it was created in Made in Qing Dynasty China for a European customer.

"Nichol asked Anna for further age identification on the crystal skull, but Anna refused on the grounds that it had already been identified.
