Recently, an image taken by the Mars rover in the Galle crater found that the ancient soil in the Mars crater has soil samples similar to the earth's soil crack profile. Usually, such soils exist in the dry valleys of Antarctica and the Atacama Desert of Chile. There may be life on Mars in ancient times. Which of the following, if true, would best support the above conclusion? ["There are soil masses in the earth's desert soil, with a porous hollow structure and a high sulfate concentration, this feature is not obvious in the Martian soil layer.", "Analysis of chemical substances shows that the chemical weathering process of soil in the crater and the loss of olivine ore in clay sediments are close to the condition of the earth's soil.", 'These Martian ancient soil samples only indicate that Mars may have been warm and humid in its early days, when the environment was more habitable than it is today.', 'Phosphorus loss in the soil crack profile is particularly noticeable, as this phenomenon also exists in earth soil due to microbial activity.']
