Yes there is proof that there was water on Mars and possibly even life.
yes cause it has ice caps
mars
The Rover mission confirmed that Mars once had liquid water on its surface.
No, but scientists believe that there could have once been life on Mars.
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.
We have found Ice caps and possible supplies of water, although it is not abundant. Some people think there was once oceans and possibly life. We have found a fossil in Antarctica that was traced back to Mars.
Mars is full of frozen water and once was like Earth
Water forms on Mars include ice caps at the poles, frozen water in the subsurface, and possible briny water streaks known as recurring slope lineae (RSL). There is also evidence of ancient river valleys and lakes that suggest liquid water once flowed on the surface of Mars.
While the preliminary evidence would indicate a resounding "No!", further investigations seem to lead us to believe that water once existed on Mars. Therefore, floods wereat one time possible.
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.
For one, we know there are polar ice caps on mars that consist of ice. Second, there are gorges that show where water once flowed.
yes. there is water underground and scientist believe mars once had streams, lakes, and an ocean
