Looking from space, Earth is made up of land and oceans. The entire surface of the Earth is covered with a thick layer of atmosphere, like a cradle of life, full of countless vitalities. It can be said that the emergence of life has made the vast universe more colorful. It is difficult to imagine what a universe without life would be like.
The Earth has experienced billions of years of evolution and development. The oceans and land have given birth to countless creatures. Human beings are terrestrial creatures, and all of history is only a few million years old. However, apart from human civilization, no traces of the existence of any other civilization have been found so far, especially in the ocean, which represents 71% of the Earth's surface area.
Although Earth's oceans are extremely rich in biological species, with 210,000 species of marine organisms currently known, theHuman understanding of the oceans is still very limited, such as the earth's poles and the deep sea, the actual number is expected to be about 10 times the number, or 2.1 million species, and the first life also originated in the ocean. ocean. Why did such a huge biological population fail to develop an advanced intelligent civilization similar to this. humans? To understand this problem, we must first analyze the conditions in which civilization emerged. How was human civilization born? Learning to harness energy and use tools are two hallmarks of civilization.
Modern archaeological data shows that around 800,000 years ago, human ancestors began learning to use fire. This change allowed humans to begin to understand the energy of nature. Millions of years before that, humans are almost the same. like other land animalses. The use of fire gave humans a completely different path of development than other creatures. With fire, humans can expel various natural enemies, process foods to increase their lifespan, and their brains have also evolved. Slowly, humans began to use fire to make pottery and smelt metals. Until the emergence of the steam engine, human civilization has evolved since then. embarked on a fast track. Within a few hundred years, humanity has entered the space age and may even become an interstellar civilization in the near future.
