In this paper, a large number of data are used to explain that scientists first analyzed the planets in the solar system except the earth, and according to these scientific data, they came to the conclusion that there can be no life, and a large number of metaphors were used to make students more interested in the text.
According to the logical sequence of "asking questions-analyzing problems-drawing conclusions", by using the methods of illustration and comparison, it is proved that human beings have not found any signs of life in space beyond the earth so far, and will continue to solve the mystery of cosmic life with the spirit of unremitting scientific exploration. The articles between the lines reflect the rigor, scientificity and accuracy of scientific papers.

1, it can be guessed that the earth is by no means the only celestial body with life. However, humans have not found another planet with life. Theoretically, there must be a living celestial body outside the earth, but humans have not found such a planet so far.
These two results prove that there is no life on the surface of Mars in the area where the spacecraft landed. As far as the current detection results are concerned, there is no life on Mars, but the possibility of life on Mars cannot be ruled out. For example, in the area where the spacecraft has not landed, in the rocks below the surface of Mars, and so on.
