Is it unrealistic to colonize Mars?

Mars has always been a planet that people pay close attention to, just because it has been cultivated into the second hometown of the earth. Although the current ecological environment of Mars is not suitable for human habitation, with human intervention and transformation, the future of Mars will be earth-shaking. However, is it really necessary for human beings to make great efforts to transform Mars? Apart from Mars, is it impossible for human beings to find a planet suitable for direct migration? After all, the transformation of Mars is not difficult. Mars has no atmosphere and magnetic field. Even if it has liquid water, it may not be enough for human survival.

In fact, scientists can find a second planet that may have given birth to life without leaving the solar system, and the possibility of future migration may be much greater than that of Mars. This planet is not a planet, but a satellite. It is Saturn's largest moon Titan, ranking second in the solar system.

Titan, also known as Titan, is the only satellite in the solar system with an atmosphere. Compared with Mars, there are not many advantages. For a living planet, atmospheric magnetic field and liquid water resources are indispensable. Although this is based on the earth's ecological environment, these ecological environments are indispensable if human beings want to immigrate to Titan or any planet. Humans don't mean that planets with huge differences between the universe and the earth's environment can't give birth to life.

Titan's atmosphere is thicker than the earth's, and NASA has also detected the composition of water vapor and methane gas in Titan's atmosphere, so it is speculated that Titan may have given birth to life, because methane is generally a gas generated by a series of chemical reactions after the death of organic matter, at least on the earth, this possibility exists.

Coupled with the composition of water vapor in the atmosphere, scientists think more. Although the surface temperature of Titan is-179.438+06℃. But if there is solid water on Titan, it will sublimate where the eyes shine, and water has always been regarded as the source of life by human beings. Humans can't ignore the probability that Titan is likely to have life.

Since Titan's environment far exceeds that of Mars, why do scientists still focus on Mars? I can't help it, but human civilization and scientific and technological development are too backward. With the current ability of human beings, landing on Mars is the limit. Titan can only consider landing when its technology improves in the future. Do you think there is life on Titan?
