Do you know why we haven't discovered aliens? Have you ever thought that the earth and everything on the earth may have been carefully designed? Next, let’s tell you how coincidental the earth and life appeared. Let’s start with the solar system. Our solar system is perfectly in the habitable zone of Milky Way . If we are too close to the center of the Milky Way, we will be swallowed by the gravity of the giant black hole in the center. If it is too far away from the center of the Milky Way, it will be difficult to form heavy metal element , which lacks the necessary conditions for life. In this distance between not far and not too close, it is full of explosion supernova. The solar system has cleverly escaped all dangers and selected this excellent location, an open and stable area, and the cosmic rays are relatively There are also much less.
One of the necessary conditions for the generation of life on Earth is liquid water. The reason for liquid water on Earth is that the earth is not far from the sun or just close. The earth is also in the habitable zone of the solar system. If the earth is a little far away from the sun, the earth will be covered with ice and snow. If the earth is a little closer to the sun, the liquid water on Earth will be evaporated. Venus is an example. The sunlight that reaches Venus is only two minutes earlier than the earth, and the surface temperature of Venus is as high as 464 degrees Celsius.
In the solar system, only the earth is in the habitable zone. The only satellite on Earth, , is also equally mysterious. It is more like the moon tailored for the earth. As the Earth's satellite, it is too big. Other planets have never had such a large satellite. Its diameter is 1/4 of the earth. Its size just stabilizes the axis of rotation of the earth, giving the earth four seasons, oceans, and stable tides. These are also necessary conditions for the generation of life. In addition, Earth magnetic field is also indispensable. If there is no Earth magnetic field, the atmosphere will be easily blown away by solar wind , and the earth will also become a barren land. Mars is an example. Moreover, the atmosphere blocks all our unnecessary ultraviolet rays and gamma rays and , leaving only the sunlight we need, as well as the powerful gravity of Jupiter and Saturn protecting the earth from the impact of meteorite . These are only a small part of the many conditions, just as everything is prepared for the emergence of life on Earth. However, we have experienced many coincidences since we evolved from single-cell organisms to the current civilization.
Some scientists made this metaphor. The probability of human civilization being produced in the universe is like a gust of wind blowing some parts into the sky. After that, the parts blown by the wind are assembled into a driving car. So many people think that the earth and human beings are created by higher civilizations. But in fact, it is precisely because of our appearance that these conditions have become very coincidental. The probability of life being produced is much smaller than the probability of you winning a lottery for one year. How lucky you are, so you should love it even more.
