Mars has water,rocks.we can live on Mars..

Curiosity, which landed on Mars in 2012, is currently exploring a unique feature known as the “Marker Band” in the foothills of Mount Sharp. Rocks in this area show the clearest evidence yet for waves the mission has ever seen: rippled textures that formed billions of years ago, as waves on the surface of a shallow lake stirred up sediment on the lake bottom.

Farther up the mountain, Curiosity can see more evidence of ancient water: wet landslides caused boulders and other debris to slip down into a valley. Curiosity caught a glimpse of this debris from a distance, but the rover's team hopes to get a closer look later in 2023.
