The earth is the homeland where mankind has survived for millions of years. Before mankind left the earth, we always believed that there were other intelligent life outside the earth, and that the vast universe should be very lively.
But when human beings finally walked out of the earth with the help of science and technology, what appeared before our eyes was a lonely universe. We did not see the lively starry sky, did not see any extraterrestrial life and extraterrestrial civilization.
So does alien life exist? Regarding this issue, the general opinion in the scientific community believes that extraterrestrial life exists. Because the universe is so large that we cannot imagine it, even the Milky Way with a diameter of only more than 100,000 light-years has as many as 100-400 billion stars, and the number of terrestrial planets is as many as trillions.
With an unimaginable base number, it is clear that only the planet of life, the Earth, does not make sense. Since there is a high probability of other living planets and even alien civilizations in the universe, where are we going to look for them? Before human beings became an interstellar civilization and were incapable of interstellar voyages, the area we could explore was limited to the solar system.
There are eight planets in the solar system. Standing in space, we can clearly see the huge difference between the earth and other planets. Putting the eight planets together, the earth is the most dazzling and beautiful one. This may be the unique demeanor of the planet of life.
Although the solar system does not have a second planet comparable to the earth, nor does it have a second intelligent civilization, scientists believe that on a certain planet, there may be some simple life, such as bacteria and other microorganisms. Because microorganisms are very adaptable to the environment, there are microorganisms in many harsh environments on the earth.
Other planets cannot adapt to the survival of human beings, but microorganisms may thrive in them. Therefore, after human beings walked out of the earth, scientists began the journey of searching for extraterrestrial life in the solar system, and among the planets we explored, the most likely existence of extraterrestrial life was Mars.
Mars, also known as the red planet, has its own unique beauty when viewed from a distance. Like the earth, Mars is also in the habitable zone. It is our neighbor and has many similarities with the earth. The environment of Mars is very similar to some desert environments on Earth, except for the two poles, there is no water on the surface.
Of course, according to the latest discovery of Mars exploration, scientists speculate that there may be a lot of water resources under the surface of Mars. When the human probe reaches the surface of Mars, we see a desolate world without any signs of life.
However, as the probe continues to explore Mars, scientists’ attitudes towards Mars are constantly changing. At present, we know that there are a large number of ancient riverbeds on the surface of Mars. This shows that there were oceans on the surface of Mars a long time ago. And water is the source of life. Therefore, scientists believe that ancient Mars may also be a living planet, but after a drastic change, it became what it is now.
The current environment of Mars is unlikely to have complicated organisms, but because ancient Mars is a beautiful planet, coupled with a series of discoveries on Mars now, scientists boldly guess that there may still be some simple microorganisms on Mars, and it is not even ruled out. Some more complicated lives appeared.
If there is life on Mars, it may be considered by many people to be very good news, and it can finally prove the existence of life on Earth. However, in the opinion of some scientists, if life is found on Mars, it may be very bad news. Why?
First of all, we must understand that Mars is very important to the future of mankind. Scientists actively explore and study it, mainly to regard it as the second home of mankind. With the continuous advancement of human science and technology, it is inevitable to move towards the starry sky in the future. There is only one earth in our home now, and there will be many in the future.
Before human beings are capable of interstellar voyages, our second home can only be found in the solar system, and Mars is undoubtedly the best choice. Although the current Martian environment is not suitable for human survival, it is not as bad as Venus. As long as we carry out a series of transformations on Mars in the future, it is possible to make it a new earth suitable for human survival.
The new home that mankind has found naturally hopes that there will be no existence of things that can threaten our existence. The planetary environment is the first test that mankind will face, and this can be changed and overcome through certain environmental transformations. The second threat to human existence is the life on the planet. We must understand that the life born in different planetary environments is naturally different.
Life on the earth is formed outside the earth’s environment after billions of years of evolution. This is the unique life form and characteristic of the earth. Although human beings are advanced intelligent life, our body is not invincible. There are many microorganisms that can seriously threaten human health and life.
Bacteria and viruses pose a great threat to human beings. I believe that many friends have seen the terribleness of viruses this year. Viruses are a kind of tiny life that we can’t see with our naked eyes. It is very difficult for us to prevent. Although these microorganisms on the earth are a certain threat to human beings, we are also the native life on earth, and we naturally have a strong immunity to these tiny lives.
If there is life on Mars, it will most likely be these tiny microorganisms. They have survived and evolved in the Martian environment for billions of years, and naturally formed a life form different from that on Earth. Life on Mars is different from life on Earth. When the two meet, there may be a huge threat.
The human body can resist the tiny life on Earth, but it may not be immune to life on Mars. Under such circumstances, human beings may face the challenge of life on Mars if they want to live on Mars. It can be seen that if life is discovered on Mars, it may be very bad news for mankind, and it may add many variables to mankind’s desire to colonize Mars.
Of course, human beings are intelligent civilizations, and they have stepped out of the technological era. With the powerful force of science and technology, everything can be overcome and overcome. Even in the future, when we discover life on Mars, and they are a threat to humans, we can also research and develop relevant vaccines against the threat of life on Mars. Humans’ desire to colonize Mars and make it a new earth will eventually come true.
In fact, after human beings move to the interstellar world in the future, they will find new earths and homes suitable for human survival. On these new earths, there is a high probability that native life has been born. The reason is simple. An environment like the earth can give birth to life and give birth to human beings. On a planet that is very similar to the earth, it is naturally easy to give birth to life.
Therefore, the future of humanity’s interstellar colonization will not be unsuccessful. The new homes we discover may have life, and even wisdom and civilization. If we want to possess, we need to face the challenges of the original inhabitants. Only through each challenge can human beings continue to grow stronger and eventually stand on top of the universe.
