1, the so-called livable planet is a planet that is suitable for life and can adapt to life. In fact, it can't be called Yi Bei planet, it is a planet suitable for life. Simply put, the earth has sufficient lighting environment, which can provide energy for the survival, growth and development of natural creatures. It is precisely because it is suitable for biological survival that it is defined as a livable planet.
2. The reason why aliens are sought based on livable planets is also because the existence form of carbon-based life has certain conditions for the outside world. In fact, it has to be said that most of the earth exists in the form of carbon-based life, and because of this, scientists predict that aliens may also form in the form of carbon-based life, so it is reasonable to seek aliens based on livable planets, and we can better seek carbon-based life.
At present, scientists think that the form of life may be beyond people's cognition, so it is also controversial to find aliens. In fact, we have to say that many scientists question this and think that the life form of aliens may have exceeded our cognition. It is precisely because of this that seeking aliens on the basis of a livable planet may not be able to convince others. Because of this, this statement is not completely correct.
In fact, for us, the so-called livable planet is a planet suitable for life, but whether it is scientific to seek aliens based on livable planet depends on the state of life forms in the universe, so whether it is scientific needs further testing.
