The reason why Mars has no water because its atmosphere is too thin, so the sun vapoured all the water on Mars and it does not have any plants to make it rain there.
Rain is a liquid because it is water.
Scientists have proven that liquid water once existed on Mars. Currently Mars is too cold and atmospheric pressure is too low for water to remain liquid, so both temperature and surface pressure must have been higher.

Scientist believe that the planet Mars used to have flowing liquid water. Now, the water on Mars exists almost exclusively as ice.
They do not think that conditions for life must exist inside Enceladus; they merely think it is possible. The Cassini probe has detected geysers venting ice and water vapor from beneath the icy surface of Enceladus, indicating that there is liquid water beneath the ice. Scientists consider liquid water to be the best indicator for a planet or moon to potentially be suitable for life.

As far was we know the development requires water in its liquid for to be present and a source of energy to supply/drive chemical reactions. We know that deep down Europa has a liquid layer (of water) and the geysers of this water into space proves that there is energy in Europa's core.
It may have oceans of liquid water under its layers of water ice. Scientists want to know if these oceans (assuming they are there) contain any forms of life.
Scientists believe that there is liquid water, under the crust of Europa.
Why scientists believe a liquid water ocean might exist on the moon Titan
Because its rocks clearly show that it once had oceans made of liquid water.
Rain is a liquid because it is water.
Scientists have proven that liquid water once existed on Mars. Currently Mars is too cold and atmospheric pressure is too low for water to remain liquid, so both temperature and surface pressure must have been higher.
Mars is too cold for liquid water to flow on the planet surface
No, it can only be liquid the reason why is that gas floats around and liquid holds the shape of its container. So water can only possibly be liquid.

Scientists usually refer to it using the highly technical term water.
