Whether there was another civilization on Earth before humans, we are not sure yet. Although some scientists and archaeologists believe that other intelligent life forms have existed on Earth, there is no conclusive evidence for these views. The scientists were looking for evidence of the existence of other intelligent life forms by studying the history of biological evolution on Earth and some events in Earth's history. However, because the emergence and evolution of life on Earth is a very complicated process, what we currently understand is only a part of it, so more research and evidence are needed to determine whether other civilizations exist. Although we can't be sure if there are other civilizations on Earth, scientists are still trying to find answers and better understand life on Earth and in the universe by studying Earth's history and the evolution of life.
According to the current scientific knowledge, there was no conclusive evidence of the existence of a developed civilization before the emergence of humans on Earth. Although some scientists had put forward some assumptions, these assumptions had not been proven or falsified, so it was impossible to draw a definite conclusion. However, there was some evidence in history that a highly developed civilization once existed on Earth. For example, the ancient Egyptian civilization, the ancient Indian civilization, the ancient Greek civilization, and the ancient Roman civilization could all be traced back to thousands of years ago. They had high achievements in culture, technology, art, and architecture. Although we can't rule out the possibility of other highly developed civilizations, current scientific knowledge and technology can't prove their existence.
According to the current scientific evidence, there was no conclusive evidence that there had been other civilizations on Earth. However, some scientists and archaeologists believe that there was once a highly developed civilization on Earth, but these civilizations may have gone extinct. According to the research of some archaeologists, there were some highly developed civilizations on Earth, such as the ancient Egyptian civilization, the ancient Indian civilization, the ancient Greek civilization, and the ancient Roman civilization. However, the origin of these civilizations in historical records can be traced back to about 3000 B.C. Before that, there may have been other highly developed civilizations on Earth, but whether these civilizations were recorded or discovered is still unclear. Some scientists believe that there were some highly developed alien civilizations on Earth, but these civilizations may have gone extinct due to various reasons such as technological explosions, interstellar collisions, cosmic radiation, etc. The existence and extinction of these civilizations may be determined by the random and unpredictable nature of the universe. In short, there was no conclusive evidence in the scientific community to prove that other civilizations once existed on Earth, but this did not mean that this issue was not controversial and worthy of discussion.
There was no conclusive evidence of the existence of a civilization similar to humans in the Earth's oceans because the cost of exploring the ocean civilization was very high and humans did not have the technology to explore the ocean. However, science fiction novels and movies often depicted civilizations in the ocean. These civilizations might use the ocean resources to build powerful ships and machines and develop a high-tech civilization. Although there was no direct evidence that there was a civilization similar to humans in the ocean, many science fiction novels and movies depicted such a plot, which filled people with imagination and expectations of marine civilization.
According to what he had learned so far, there was no evidence that any civilization more advanced than mankind existed. Before the appearance of humans, there were many different life forms on Earth, but none of them formed a highly developed civilization. This is because a highly developed civilization requires advanced technology and infrastructure that does not exist on planets other than Earth. Although humanity's current understanding of the universe is still very limited, we have already discovered some signs of extraterrestrial life, which indicates that extraterrestrial civilizations may be more advanced than humans. However, we have yet to find conclusive evidence of the existence of extraterrestrial civilizations, so we cannot draw a definite conclusion. It's important to note that this is just a simple conclusion based on current knowledge. As we learn more about the universe and life, we may come to different conclusions.
The living beings on Earth were from a single civilization to another civilization, not from one civilization to another. This is because the creatures on Earth evolved from a common ancestor. They were all part of the same civilization on the early Earth. As time passed, this civilization continued to develop and evolve, interacting with other civilizations and influencing each other, causing different creatures to gradually evolve into different civilizations. For example, humans and other mammals belonged to the same species in the early days of Earth. Later, the contact and communication between humans and other mammals led to the gradual evolution of humans into civilization, while other mammals also developed different civilizations. However, it was important to note that the creatures on Earth did not have the ability to transmit civilization. They could not pass on the knowledge and skills of civilization through genetics or mutation, so the development of each biological civilization was independent and unique.
Based on what we have learned so far, we cannot be sure if there were one or more groups of humans and civilizations on Earth long before we were born. Because what we know about the origin and evolution of human beings and civilizations is based on the results of modern scientific research, and these studies are carried out under the current circumstances of human existence. Although we can't be sure if there were other humans and civilizations in the past, some literature may describe stories that transcend modern human civilization, and these stories may involve the existence of other civilizations. These stories were not necessarily scientific assumptions but literary creations.
Could the alien signal be sent by another advanced civilization in the universe to explore the universe? Could the so-called aliens be humans from the highly civilized Earth? This was an interesting question that could be discussed from different angles. According to current scientific understanding, there are many different galaxies and planets in the universe, some of which may have the possibility of life. Therefore, some scholars believed that the extraterrestrial signal might be a signal sent by some life forms to explore the universe. It's possible because some detection equipment can also emit weak signals that can be received and interpreted by other life forms. On the other hand, some people believed that the alien signal might have been sent by a high-tech civilization because they had more advanced technology and stronger detection capabilities. In this case, these advanced civilizations might use their technology to detect other planets and planets in the universe and send signals to warn or communicate. As for whether aliens were human beings, that was a complicated question. Some scholars believe that aliens may not be humans on Earth because they may have different life forms or technological levels. For example, some extraterrestrial life forms might live in extreme environments that humans could not adapt to. In addition, aliens may have higher intelligence and technology than humans, so they may not need humans to lead or control them. In short, there were still many unknown factors and speculations about alien signals and aliens. With the development and exploration of science and technology, these questions might get a deeper understanding and answers.
In the movie Wandering Earth, humans might encounter extraterrestrial civilizations during their escape from Earth. However, there was no conclusive evidence that extraterrestrial civilization really existed. Science fiction often depicted the existence of outer space and planets with life. Civilizations on these planets might establish contact with humans on Earth or pose a threat to humans. But so far, we have not found conclusive evidence that these ideas are real. The scientists have been looking for signs of extraterrestrial life but have yet to find conclusive evidence. Therefore, we don't know for sure whether extraterrestrial civilization really exists.

Is life on earth going through a cycle: destruction-civilization-destruction-civilization? What humans know and study is only one part of the cycle This was a controversial topic. Some people believe that life on earth is a continuous cycle, and every civilization has a life cycle that will eventually be destroyed and restarted. These people believed that life and civilization on Earth constituted a cycle similar to the " life cycle ". Every civilization would rise again after being destroyed. Others, however, believe that life and civilization on Earth are not a simple cycle but a combination of many different factors. They believed that life and civilization on Earth were a complex and dynamic process in which many different factors interacted and influenced each other, allowing life and civilization to take on different forms at different times. In short, there were different views on whether life and civilization on Earth were a cycle. What humans know and study is only one part of the cycle, but we can learn more about the nature and possible development of life and civilization through continuous exploration and research.
