The relationship between humans and the earth
The relationship between humans and Earth was complex and multi-layered. From the perspective of survival, Earth was the home that humans relied on. Earth provided all kinds of resources needed for human survival, such as water, air, land, and so on. However, with the growth of the human population and the development of science and technology, the demand for Earth's resources was increasing, and it was approaching the red line of the Earth. From the perspective of development, Earth had witnessed the development of human civilization. Human civilization had gradually developed from primitive society to modern civilization. In this process, humans had constantly transformed the Earth's environment. This transformation had both a positive side, such as transforming part of the land into fertile farmland suitable for cultivation through agricultural activities, and a negative side, such as the reduction of biological richness, climate change, environmental pollution, and other problems caused by human activities. From the perspective of mutual influence, the fate of mankind and Earth was closely related. Human activities would have a major impact on the Earth. For example, industrial production would release greenhouse gases to affect the climate, and over-exploitation of resources would destroy the Earth's ecological balance. Changes in the Earth's environment would also have adverse effects on humans. For example, frequent natural disasters and resource scarcity would bring challenges to human survival and development. In terms of perception, humans 'understanding of Earth was also constantly changing. Early humans regarded the Earth as a mother-like existence and relied on the gifts of the Earth to survive. As humans mastered more and more scientific and technological power, human attitudes towards the Earth began to become complicated. Some people tried to conquer the Earth, but this concept ignored the fundamental dependence of human beings on the Earth. In short, the relationship between humans and the Earth was dependent and influenced by each other. While developing their own civilization, humans needed to respect the ecological laws of the Earth and protect the Earth's environment to ensure the sustainable development of human civilization.

Are there humans on Super Earth?
There was currently no evidence that humans existed on the super-Earth. Although many super-Earths had been discovered and some were in possible habitable zones, there were no signs of humans or other intelligent life on these planets.
Prehistoric Humans on Earth
Prehistoric humans on Earth referred to the ancestors of humans who lived before 5000 B.C. and did not leave any historical records. The study of prehistoric humans did not rely on written records. Instead, it relied on stone tools, pottery, stoves, food scraps, abandoned settlements, monuments, tombs, rock paintings, and other archaeological research objects. It also used evidence of past environmental changes, such as pollen grains and beetle wings in ancient deposits. It could also interpret past conditions through the genes carried by modern people and the language they spoke. Prehistoric humans include different types. Homo Erectus lived between 2 million and 200,000 years ago, from the early to the middle of the Pleistocene. The brain capacity was 800 - 1200 milliliters. The brain structure was more complex and may have produced language. Its fossils were found in Java, Europe, Africa, and China.(Yuanmou Man, Lantian Man, Peking Man, etc.). The early Homo Evolutis lived between 250,000 and 45,000 years ago. Geologically, it belonged to the late Middle Pleistocene to the late Pleistocene. Archeologically, it belonged to the middle of the Paleolith. Their fossil sites were distributed in more than 70 places in Asia, Africa and Europe. Their bones retained many primitive characteristics and their brain capacity was still small. It was generally believed that they were directly evolved from Homo Erectus. Late Homo Evolutis evolved from some early Homo Evolutis about 100,000 years ago, and its distribution range expanded significantly. In addition to Europe, Asia, and Africa, there were also America and Australia. There were obvious racial differences in humans in different regions. In palaeoanthropological studies, modern humans about 10,000 years ago were regarded as late Homo Evolutis. After the emergence of the earliest human, Homo Evolutis, early humans had a diverse existence. Before the emergence of modern humans, there were at least 21 species of humans on Earth. However, only Homo Evolutis evolved into modern humans, and many other species of humans went extinct. The reason for its extinction may be related to the encounter, integration, and various catastrophes of Homo Sans after they left Africa. For example, modern science believed that human beings originated from Africa. After Homo Evolutis left Africa, they would find other "humans" on the new continent. There might be genetic fusion between different human species. At the same time, prehistoric human civilization had been destroyed by earthquakes, floods, volcanoes, alien star impacts, continental plate movements, and sudden climate changes.
Can humans leave Earth?
Theoretically and in the long run, it was possible for humans to leave Earth, but they faced many huge challenges. From a technical point of view, the current human manned space technology was still relatively limited. For example, the farthest manned space project had only reached the moon 350,000 kilometers away from Earth. If they wanted to carry people to more distant places, they still needed to solve a lot of technical problems. The speed of space travel was also a key issue. The diameter of the solar system was more than one light year, and humans were still very far away from sub-light speed. The fastest spacecraft, New Horizon, needed nearly three months to reach Mars. Manned spacecraft were even slower. The physiological structure of humans was also a big obstacle. After working in space for a period of time (as short as 100 days), the body function and brain structure would undergo significant changes. Although these changes could be recovered after nearly a year after returning to Earth, it was difficult to determine what changes would happen to the human body and whether it could recover if they were to travel further and stay in space for a longer period of time. Moreover, the new planetary environment (such as Mars, which was only one-ninth of Earth's mass and had much less gravity than Earth) would also affect human body functions and brain structure. There was currently a lack of data to study whether humans could live on such a planet for a long time. However, human beings had the spirit of exploring the unknown. There was a contradiction between the development of civilization and the Earth's ecology (such as the limited resources on Earth, development would continue to consume resources, and problems such as global warming were difficult to completely solve), which also prompted humans to seek to expand new living space. If the technology in the future was advanced enough, it might become a reality for humans to leave Earth.
What are the prehistoric humans on Earth?
There were a few types of prehistoric humans on Earth: 1. [Homo Erectus: A member of the human family that lived between 2 million to 200,000 years ago, from the early to the middle of the Pleistocene Era. In the early days, it was called the ape-man.] Its brain capacity increased to 800 - 1200 milliliters, and its brain structure became more complex. It might have already produced language. The earliest discovery of Homo Erectus fossils in the world was on the island of Java in Indonesia. It was also found in Europe and Africa. The Homo Erectus fossils found in China included Yuanmou Man, Lantian Man, Peking Man, etc. 2. ** Early Homo Evolutis **: Also known as the "ancients", lived between 250,000 and 45,000 years ago. Geologically, it belonged to the late Middle Pleistocene to the late Pleistocene, and archaeologically, it belonged to the middle Paleolith. The fossil sites of early Homo Evolutis were distributed in Asia, Africa and Europe, with more than 70 fossil sites. They were not completely modern humans. Their bones still retained many primitive traits, and their brain capacity was still relatively small. It was generally believed that they were directly evolved from Homo Erectus. 3. ** Late Homo Spico **: also known as "modern Homo Spico" and "new species". About 100,000 years ago, some early Homo Evolutis evolved into late Homo Evolutis. During this period, the distribution of human beings expanded significantly. In addition to Europe, Asia, and Africa, there were also America and Australia, and there were obvious racial differences between humans in different regions. In the study of palaeoarcheology, modern humans from about 10,000 years ago were generally regarded as late Homo Evolutis. In addition, the American team of scientists said that before the emergence of modern humans, at least 21 species of humans existed on Earth, such as the Denissos found in ancient caves in Siberia, the possible Luzon people found in the philippines (controversial), and the Flores people found in Indonesia.
How many humans are there on earth?
As of October 14, 2023, the global population had reached 8.032 billion. According to the report "World population prospects 2024" released by the United Nations Department of economic and social affairs (DESS) on July 11, 2024, the global population will reach a peak of about 10.3 billion in the 1980s, and then the population will slowly decline to 10.2 billion before the end of the 21st century.
Does Earth like humans?
Earth did not have emotions. It could not have feelings of " like " or " dislike " like living creatures. However, from the perspective of the relationship between the Earth and humans, humans were born and developed on Earth. Earth provided the living environment for humans, including suitable temperature, air, water, and food sources. From this perspective, the Earth was the foundation of human survival. However, many human activities, such as excessive demand for resources and destruction of the environment, did not bring positive development to the Earth's ecological environment. Instead, it caused problems such as resource depletion, environmental pollution, and reduction of biological species.

Was there another civilization on Earth before humans?
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.
A place that humans on earth cannot explore
I recommend " Digging the Earth ", an urban supernatural novel written by Fu Bao. There were many unsolved mysteries on Earth, such as the underwater pyramids, the continent under the Antarctic ice sheet, and the crystal skull that could sing and talk, which hid information about the origin and death of mankind. The protagonist, Zhou Yun, explored every corner of the earth to find lost treasures. However, this author was not very reliable. Out of the ten books, only one was completed. Most of the others were incomplete. This book might follow suit. There were also repetitions, numbers, and meaningless words in the text. It was unknown if they could be changed after they were published. However, it was quite enjoyable to watch. It was a little like Golden Pupil, but with a new element. Cataclysm of the Earth, a science fiction novel written by Shi Lie. The universe had a mysterious void corridor. The supernova explosion did not destroy Earth but allowed life to evolve again. The young man grew up on Earth and rose in the universe, leading Earth's civilization to prosper. Doomsday novels were rarely written well, but this one was worth reading. " Two-week Female Empress: Something's Wrong with the Plot!" It was a light novel written by Strawberry. Li Yunsheng entered the book he wrote and became the assistant. He relied on the reward of awakening the emotional system to fight with the empress. The empress held the script in her hand and waited for him to enter the game, but she realized that the plot was wrong. The setting was a little scattered and the foreshadowing ended hastily, but the plot was interesting. 'Global High Martial Artist Reputation Accomplishment' was a heavenly novel written by Meng Kun. Liu Qi had transmigrated to a parallel world and relied on the reputation system to exchange for all things. When he started cultivating the Dragon Elephant Bo-Ruo Technique, his sect would also change because of him. " Earth No. 7 Strategy Guide ", a science fiction novel written by Yun Mou. No. 7 had never come to Earth to look for his target, but he realized that he had run to the wrong parallel space Earth. This book had become a ten-thousand-year-old pit, but someone was still at the bottom of the pit.
Aliens Invading Earth, Disguising as Humans
In science fiction, there were scenarios where aliens invaded Earth and disguised themselves as humans. In some descriptions, aliens disguised as humans was not a simple transformation, but rather, they used their technology to cover their original appearance, similar to the layer relationships in design software. The disguised aliens may have some characteristics that expose their identity, such as the disguised human's eyes and mouth not moving, pupils without light, hands with weak blue light, moving faster than ordinary people, and a special smell on the body. In some stories, aliens disguised as humans with the purpose of invasion. They came from planets that were on the verge of extinction and came to Earth to obtain resources and food. This made it difficult for the people on Earth to distinguish between their own people and aliens. In order to defend the Earth, the rebels on Earth had to pick up weapons and fight the disguised aliens to the death. In addition, there were some plots that involved aliens launching various attacks after their disguises were exposed, or Earthlings counterattacking after discovering the alien disguises.
Why do humans dominate the earth?
There were many different views on why humans could dominate the Earth. One of them believed that humans had a unique ability to " recognize ", which was the fundamental difference between humans and other creatures. The so-called " cognitive visualization " meant that humans could express the cognition in the brain through external carriers, such as knotted rope records, hieroglyph on pottery, oracle bone inscriptions, and pictures carved by primitive people in caves. This ability allowed humans to record and pass down their knowledge. As human social activities increased, their knowledge continued to accumulate, and humans became more and more " intelligent ", thus relying on these accumulated knowledge to conquer the world. There was also a view that the prefrontal lobe in the human brain played a key role in the process of humans dominating the earth. There were also views that scientific progress was an important factor in humans becoming the masters of Earth. The development of science allowed humans to gradually recognize their position in the universe and constantly improve their abilities. However, there were also people who questioned whether humans really dominated Earth, because there might be other life forms in the universe, and Earth was not a very special existence in the universe.
