Do you think the human desire to plant grass on Mars can come true? why

It's hard to be sure. It has been found that there is water when there is ice on Mars, and it has been confirmed that there is methane on Mars. Water is the source of life, and methane is the gas released by life. There may be life on Mars. If humans continue to explore Mars and find that there is life, it is likely to realize their desire to land on Mars and plant some grass, but it is still too early.
