water comes on earth surface because of soil because soil has moisture.. moisture is in the form of vapours.

Hey mate here is your answer
First, I’d like to dispel any idea that Earth is unique in having water. It is not.
Water is present throughout the solar system. Mercury may have water ice in craters at its poles (as may our moon). Venus may have had substantial water but lost most of it. Mars has ample evidence of former flowing surface water and still has water ice at the poles and probably under the surface. Jupiter has small amounts of water as vapor in its clouds, but some of its moons, such as Europa, may have an ocean of water. Like Jupiter, Saturn may have water vapor in its clouds and likewise its moon Enceladus may have an ocean of water beneath an icy crust and Titan may be primarily water ice and rocky material. Neptune and Uranus are ice giants, and have a large amount of water ice mixed in their atmospheres. Even poor, demoted Pluto has water ice, including an interior core made of ice. (So do other dwarf planets Eris, Haumea, and Makemake. And Ceres may have some interior ice, too.) And there are probably close to 3,000 comets, and they mostly or perhaps all consist in a nucleus that consists of dust, various molecules, and water ice.
So, the solar system is swimming in water — or at least clinking away with water ice. Therefore, the real question is, where does all this water come from not just for Earth but for the entire solar system — and the cosmos in general?
Simply put, water is composed of hydrogen and oxygen. Hydrogen is the most common element in the universe. It may make up as much as three quarters of the mass of the universe. And oxygen, produced through stellar fusion, is the third most common element in the universe; though it makes up only about one percent of the mass of the universe, it is a huge universe. (On Earth, oxygen is the most common element, making up nearly half of the Earth’s mass! The fourth most common element is carbon, also produced through stellar fusion, and making up about a half percent of the mass of the universe. Fortunately for us that carbon is so abundant, since we are carbon-based life forms.)
You can think of water as the “ash” (combustion produce) of “burning” hydrogen to produce hydrogen dioxide, H2O, or water. The water on Earth, and the water abundant throughout the solar system as described above, results from the abundance of the most common elements in the universe and for their atomic properties that allow them to combine as they do to form water.
Hope this answer will help you!!!
