Is there really extraterrestrial life in the universe?

There are no miracles in the universe. At present, the only life planet suitable for human survival is the earth, and some people suggest that there is alien life in the universe. Does this assumption hold? Then let's use constellation knowledge to uncover this mystery! Let's have a look!

Is there really extraterrestrial life in the universe? So far, human beings have not found extraterrestrial life-whether it is low-level life or intelligent life-on other celestial bodies outside the earth. However, many people think that there is a high probability of alien life, because there are too many planets with similar conditions to the earth, and the environment of the universe allows the existence of life on the earth, so it is entirely possible to allow the existence of alien life, but human beings have not been able to detect it. In the vast universe, there are countless stars, and there may be planets around them. Astronomers have now discovered thousands of such planets. Some stars even have as many as eight planets like the sun. According to this view, there may be stars with more planets than the sun in the universe. Therefore, scientists such as CarlSagan and StephenHawking think that it is not advisable to say that there is no life except the earth. One possibility is that life occurs independently in many parts of the universe. Another possibility is that life was born in one place and then spread to other habitable planets. These two hypotheses are not necessarily mutually exclusive.

Planets and examples believed to have extraterrestrial life. The places where humans believe that life once existed or still exists include Venus and Mars. A satellite of Jupiter, like Europa; Saturnian satellites, such as Titan and Enceladus; Planets outside the solar system, such as gliese 58 1c, G and D, are newly discovered planets with similar mass to the Earth, which are in the habitable zone of their galaxies and may contain water. As for those who believe that UFOs come from outer space and that aliens kidnap people on earth, most scientists think it is not credible. Many UFO sightings have proved to be human-made aircraft or spaceships, or just some pranks.
