Recently, the images taken by the Mars rover in the Galle crater found that there were soil samples similar to the earth's soil crack profile in the ancient soil in the Martian crater
The loss of phosphorus in the soil crack profile is of particular interest because this phenomenon also exists in the earth's soil, which is due to microbial activity.
 Usually, such soil exists in the Antarctic Dry Valley and the Atacama Desert in Chile, suggesting that there may be life on Mars in ancient times
