How many years has it been since humans appeared?
Based on the known fossil evidence, humans in the broad sense (able to walk upright for a long time) appeared more than 5 million years ago, while humans in the narrow sense (able to make and use tools with increased brain capacity) appeared more than 2 million years ago. However, there were also studies that showed that about 100 million years ago, the ancient ancestors of humans already existed, but at that time, they lived in the shadows of dinosaurs in a small and arboreal way. In 1987, a 290 million-year-old fossil similar to human footprints was discovered. However, this discovery contradicted modern scientific research and inference of the time of human appearance. Modern science believed that humans could not have appeared during the Permian period (290 - 248 million years ago). The novel "Hundred Years of Spaceship" is equally exciting.

Was there a developed civilization on Earth before humans appeared?
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.
10 billion years ahead of humans
If there was a super-Earth in the habitable zone, life might have already been born on it. It might even have evolved into a civilization as early as 10 billion years ago. This civilization might be at least 5 billion years ahead of mankind. However, this was only a theoretical speculation. There was no conclusive evidence to prove the existence of such a civilization that was 10 billion years ahead of mankind. If such a civilization existed that was 10 billion years ahead of mankind, according to our understanding of the development of civilization, its technology and level of civilization would far exceed human imagination. It would be a height that mankind could not reach at present.
Will there still be humans after 1000 years?
It was very likely that humans would still exist 1000 years later. Judging from the trend of human development, although human civilization had not yet reached the true planetary civilization, technology had advanced by leaps and bounds in the past one or two hundred years. If this trend of development continued, the technological civilization of mankind in 1000 years would far exceed the current understanding. From the perspective of human adaptability and development needs, even if the Earth's environment underwent huge changes, such as resource scarcity and frequent natural disasters caused by rising temperatures, human technology might be enough for humans to find other planets that could be migrated and continue to develop. Of course, there was also the possibility that a small number of people were still on Earth. At the same time, from the perspective of evidence of human existence, even if faced with the risk of extinction, due to the existence of burial customs in some areas and the difficulty of completely disappearing human bone fossils, evidence of human existence would remain. This also hinted that human beings might not be completely extinct, so there was a high probability that humans would still exist after 1000 years.

Pictures of Humans 1000 Years Later
Some British scientists had calculated and published a set of pictures on the Internet that humans might evolve into 1000 years later, but they could not find the specific content of the pictures. Some researchers collaborated with 3D designers to create a human model called "Mindy" from 3000 AD (1000 years later). This model presented a thick head, strange eyes, a short neck, a hunched figure, and a deformed arm. But this was more like a "serious joke", a reminder for people to find a balance between technology and health. The novel "Hundred Years of Spaceship" is equally exciting.

Humans from 10,000 years ago
10,000 years ago, humans began to enter the agricultural era, and the population began to rise significantly. This also marked the farewell of humans from the Paleolith Age, which was more than 2 million years old, and officially entered the Neolith Age. At that time, humans first tried to transform the Earth, such as planting wheat seeds around the cave and succeeding, thus entering the agricultural revolution, and the Earth entered the "Anthropocalypse". From the perspective of human evolution, human beings originated in Africa about 200,000 years ago. 60,000 years ago, they left Africa in batches. 40,000 years ago, they spread to almost every corner of the world. After continuous evolution and development, by 10,000 years ago, human body structure and brain no longer had significant evolutionary development, forming humans who could carry out innovative activities. At that time, the Fourth Glacier had just entered the interphase. The Earth's climate was warm and humid, plants flourished, and animals reproduced faster. It was relatively easy for humans to obtain food, and they began to have more energy and time. Thus, they entered the stage of activities for the purpose of innovation. 10,000 years ago, humans experienced different stages of evolution such as Homo hcapable and Homo erect. For example, Homo hcapable appeared about 2.4 million years ago. They were thin and could make primitive tools. Homo erect was the first known human to stand completely upright. They had shorter arms and stronger legs. They learned to cook food with bonfires. These evolutions laid the foundation for the development of humans 10,000 years ago.

Will humans go extinct in 100 years?
There was no information that indicated that humans would go extinct in 100 years. Although some studies claimed that humans might form the " Ultimate Pangu Continent " due to the movement of the Earth's continental plates in 250 million years, facing a great crisis of survival or even extinction, there was no evidence that humans would go extinct in a relatively short time scale of 100 years.

Celebrating the poems that appeared in the years
The poems that appeared in Joy of Life included Du Fu's Ascending and Li Bai's Drinking. These poems added poetic and emotional colors to the plot by depicting natural scenery, expressing emotions, and thinking about life. Du Fu's " Climbing High " was known as the first seven-character poem in history, while Li Bai's " Going to Drink " was famous for its lofty aspirations and philosophy of life. The appearance of these poems enriched the artistic content of Joy of Life and brought cultural enjoyment to the audience.
Never appeared in the years of celebration
The Qing Emperor's original name had never appeared in Joy of Life.
Will there still be humans after 10 billion years?
It was uncertain whether humans would still exist 10 billion years later. As time passed, the Earth would gradually age due to the effect of the Cosmic Force. Its surface temperature and sea level would change, which would make the habitable planets of humans face the threat of high temperatures and seawater swallowing, and the living space would shrink. However, humans also had some countermeasures. On the one hand, scientists envisioned migrating to other planets and using space navigation technology to find a new home. On the other hand, they were also trying to change the Earth's condition, such as suppressing the atmospheric greenhouse effect to control climate change, and conducting genetic modification and bioengineering research to adapt to the high temperature environment and the threat of mutated viruses. Moreover, humans might be able to integrate with machines to become semi-mechanical life forms, storing their consciousness and thoughts in supercomputers, thereby gaining a stronger ability to explore the universe. Therefore, as long as humans had hope, faced challenges bravely, and worked hard to find solutions, it was still possible to survive in the universe.

Humans from 10 million years ago
About humans 10 million years ago, there was a theory that humans might have been created by aliens. This statement originated from the interpretation of the oracle bone inscriptions. The word "Heaven" in the oracle bone inscriptions was thought to be a person holding a sphere. Since the oracle bone inscriptions were hieroglyphic characters, this sphere might be the spaceship that aliens used to arrive on Earth in ancient times. The so-called Pangu and others might be aliens who drove the spaceship. The ancients regarded them as gods. However, this statement lacked conclusive evidence. From an evolutionary point of view, humans evolved from Homo Erectus, and Homo Evolutis was the result of evolution from Homo Erectus. 100,000 years ago, there were six different types of humans on Earth at the same time, which indicated that the evolution of humans was very complicated. At present, scientists believed that humans originated in Africa 200,000 years ago, left Africa in batches 60,000 years ago, spread to almost every corner of the world 40,000 years ago, and entered the agricultural era 10,000 years ago. However, there were still many unsolved mysteries in the history of human evolution waiting to be explored further.
