Since Mars's atmosphere is much weaker than Earths, the sun's rays hit the ground and sort of roast the ground. Mars used to have oceans, or at least rivers, according to soil samples examined by NASA, but the sun caused them to evaporate a long time ago.

Why do scientists think Mars and Europa are good places to look for signs of life?
Because Mars and Europa are considered two of the most likely places to find liquid water. Mars is thought to have tiny amounts of water that become liquid in it's soil, theoretically allowing some particularly resilient forms of bacteria to survive, and there may be relatively large bodies of water deep beneath Mars's surface. Europa is thought to have a global underground ocean (similar to the way Earth has an underground global magma "ocean") with a volume greater than all the water on Earth.
Does Mars have oceans on its surface?
There are a few signs which lead scientists to believe that Mars in fact did, and possibly still has, water in a liquid form.
