As the Earth's population grows, scientists have to search for a second Earth suitable for human habitation on other extraterrestrial planets in the universe.

As the population on Earth grows, scientists have to search for a second Earth suitable for human habitation on other extraterrestrial planets in the universe.

Alien civilization is the focus of human scientists' research on the universe. Since the middle of the last century, researchers have devoted themselves to the exploration of extraterrestrial civilizations. In recent decades, a large number of probes and extraterrestrial satellites have been launched, but the result is regrettable because scientists cannot find extraterrestrial civilizations in the universe at all, just as all efforts are just useless.

And this does not dampen the confidence of researchers, they always sneak in the depths of the universe. From another perspective, we can understand that there are countless extraterrestrial planets in the universe. It is not easy to explore each planet seriously, because this method is tantamount to looking for a needle in a haystack.

So to this day, scientists have no evidence to prove that there is a high-level civilization in the universe, which is closely related to the current earth technology. Therefore, when there is no moment of finding extraterrestrial life, it is not necessarily that there is no life in the universe, but that our scientists have not discovered that life exists.

Coincidentally, scientists came to the universe and discovered a planet with the existence of oxygen element , and it has a high similarity to the earth on this planet, so this makes scientists feel overjoyed, because it is very likely that there is a life existence on this planet.

This is a cosmic celestial body research team composed of Japan, Swedish , the United Kingdom and the European Observatory. Through the large millimeter wave of Atacama, Chile, it discovered that the ionized signal in this celestial body was found in oxygen , and the signal ionized in this celestial body was completely shocked by scientists. According to the requirements of life for oxygen, and on the earth, it is very likely that it has a high-level civilization. Oxygen is only one aspect and needs further exploration.

If this logic continues, if there are advanced species lurking in the earth, it will still be an extremely large obstacle to scientists' exploration. This has a great relationship with the fact that current researchers have never been able to discover the existence of advanced civilizations in the universe, and even caused researchers to have the idea that advanced civilizations exist on extraterrestrial planets, and scientists have not discovered that this is due to the impact of too low civilization level, which is difficult to overcome in the short term.

Of course, some scientists believe that finding oxygen elements from the universe has no substantial relationship with extraterrestrial civilizations. It is very likely that higher civilizations are completely opposite to Earth species, that is, higher civilizations that exist on extraterrestrial planets are also very likely to live without oxygen.

The civilization on earth can appear, that is, the current human technological civilization can appear because we continued to evolve our brains more than 500 years ago and learned to use tools to develop in the direction of technology. Therefore, we have a scientific and technological civilization. We don’t know whether there have been civilizations before. We just say that humans have had several mass extinctions before. They have lived on earth much longer than humans, but they have not developed into advanced civilizations. Therefore, it can be seen that simple oxygen has space for reproduction to life.

So according to this thinking reasoning, the oxygen found this time may be just a fuss. Of course, the question of truth or falsehood involved is not judged by speculation. It also involves the subsequent research situation. Only by revealing the final scene can we judge the question of truth or falsehood. Let us humans wait and see, hoping that scientists can report us good news.
