If there is only one sun in the universe, can humans immigrate to other planets?

At present, human beings cannot live on other planets. This is because the earth is the only known planet that can support human survival. There are suitable climatic conditions and resources on the earth, such as water, food and energy, which are very important for human survival.

In addition, humans are currently unable to build infrastructure suitable for living on other planets, and there is no means of survival that can cope with the alien environment. For example, other planets may not have a suitable oxygen climate on earth, or may not have enough water resources.

Despite this, human beings are still making continuous efforts to explore space and conduct scientific research and exploration activities in space. In the future, with the development of science and technology, human beings may have the opportunity to establish colonies on other planets and establish infrastructure suitable for human survival in these places. However, this requires great progress in human technology and many technical and scientific challenges to be solved.
