Evidence from satellites in orbit and rovers on Mars show features like dried up
riverbeds. Surveys on the surface have also found minerals that can only form in water.
Astronomers believe that Mars has water, primarily in the form of ice, and there is evidence of seasonal liquid water flows on its surface. Additionally, scientists have detected water vapor in the atmospheres of several exoplanets and the icy moons of Jupiter and Saturn, such as Europa and Enceladus, which also harbor subsurface oceans.
The astronomers suppose that the water is frozen underground there. Long time ago Mars was warmer and water flows out. That's why the Curiosity car found peeblestones on the surface of Mars.
Astronomers have observed features on the surface of Mars, such as dried-up river beds, ancient lake beds, and mineral deposits that typically form in the presence of water. Additionally, data from various Mars rovers and orbiters have provided evidence of past water-related processes, such as erosion and sedimentary deposition. These combined observations strongly suggest that water once flowed on the surface of Mars.
NASA photographs of Mars are the best evidence that water has been flowing on Mars recently. During warmer periods in Mars' atmosphere, the photographs show streaks that look like streams. Scientists agree that this is evidence of water on Mars.

mars has liquid water on it
Astronomers believe Mars may have once had a more Earth-like environment with liquid water on its surface, based on evidence like dried-up river channels and minerals that form in water. They also think Mars might still have underground water sources or possible microbial life. Additionally, some researchers are investigating the idea of terraforming Mars to make it more hospitable for human colonization in the future.
Mars has evidence of erosion by water, including river valleys, channels, and minerals formed in the presence of water. Mars once had liquid water flowing on its surface, shaping the landscape over time.
There is evidence suggesting that Mars may have liquid water in the form of briny flows on its surface during certain times of the year. However, the majority of water on Mars is believed to be frozen in ice caps and underground reservoirs.
The robots sent to Mars have found Water Ice in large quantities on the surface of Mars.
