Why do scientists think Titan tops the list of livable planets?

Because there are conditions suitable for human habitation on the planet, such as water, wind, suitable temperature, humidity and soil, it is certainly suitable for human habitation.

In recent years, astronomical scientific research shows that many satellites of Jupiter and Saturn in the solar system are also considered as ideal choices for future colonization, and Titan is the representative of several immigrant satellites. Titan, as its name implies, is the sixth satellite of Saturn, but it is better known by another name, that is "titan quest". Although Thanos's hometown in The Avengers is Titan, it has been verified that Titan is not this Titan, and Thanos's Titan is actually an extrasolar planet. So it is the most suitable planet for human migration, ranking first.

Generally speaking, the data from some satellite probes show that the process of wind and rain structure on Titan is very similar to that on Earth. The energy problem of Titan should not be considered, because there are a lot of methane and ethane, but oxygen is scarce. Titan's atmosphere contains almost no oxygen. What are the necessary conditions for human survival? Let's see if there are conditions for human survival on Titan.

First of all, human beings and all living things need water for survival, and the water content of the adult human body can reach 60%. Without water, human beings can't survive. If we don't drink water for a day, we will be very thirsty. Temperature, human beings are also very demanding on temperature. The average temperature of the earth is around 15℃. Air, the earth's atmosphere keeps the temperature of the earth's surface constant and protects human beings from harmful cosmic rays. Oxygen in the air is a necessary gas for human beings to breathe.

So far, in the whole universe, the most suitable planet for human survival is the earth, and the current strength of human beings is far from reaching the level of moving to Titan or even Mars. At present, we still need to protect the ecological environment and use more new energy tools to make human life better. At that time, humans may emigrate to another planet.
