yes. there is water underground and scientist believe mars once had streams, lakes, and an ocean
Scientist have found what looks to be a place were there was once water so there is a big possibility.
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.
The robots sent to Mars have found Water Ice in large quantities 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.

They found water there.
Scientist really cannot see enough detail on Mars to be sure. There probably is water on Mars and scientist have been studying whether there used to be life there. They are looking for living bacteria and searching for tiny fossils that might indicate life,
No animal could live on mars as far as scientist know scientist have sent out the opportunity and spirit rovers that found ice which proves that there was once water on mars
