Will the earth be destroyed? Can we live on other planets?

Yes The earth will be scorched by the sun when it becomes a red giant in about 5 billion years. Tear up and devour. By then, before the earth is scorched, Mars will glow in the second spring and become a temporary habitat. After about 654.38 billion years, Mars will also be scorched, so Titan is the last place to live. Until the death of the sun, BZ, the solar system civilization completely perished.

First of all, human beings can't exist for that long, and they are likely to be extinct before that. Secondly, perhaps, new civilized creatures will have a way to master the technology of space travel and migrate to other planets suitable for survival in the Milky Way. Recently, a star about 20 light-years away from the sun has a planetary system, and the conditions of one planet are similar to those of the Earth: the main components of the atmosphere are nitrogen and oxygen, the acceleration of gravity is about 1.5 times that of the Earth, and the average temperature is-30 degrees Celsius (the average temperature of the Earth is 17 degrees Celsius).
