how water occurred on earth

Morning dew and roaring falls inspire poets. Hurricanes and typhoons wreak devastation. Melting glaciers and rising tides challenge us all, even in an ever more thirsty world.
Water is so vital to our survival, but strangely enough, we don’t know the first thing about it—literally the first. Where does water, a giver and taker of life on planet Earth, come from? When I was in junior high school, my science teacher taught us about the water cycle—evaporation from oceans and lakes, condensation forming clouds , rain refilling oceans and lakes—and it all made sense. Except for one thing: None of the details explained where the water came from to begin with. I asked, but my teacher looked as if I’d sought the sound of one hand clapping.
To be fair, the origin of our planet’s water is an intricate story stretching back some 13.8 billion years to the Big Bang. And a key part of the story, centering on two particular solar system denizens, has been hotly debated for decades.
Here’s the part we think we understand well: Just shy of a trillionth of a trillionth of a second after the Big Bang, the energy that sparked the outward swelling of space transmuted into a hot, uniform bath of particles. During the next three minutes, these primordial constituents bumped and jostled, combined and recombined, yielding the first atomic nuclei. One of the great triumphs of modern cosmology is its mathematical description of these processes, which gives accurate predictions for the cosmic abundances of the simplest nuclei—a lot of hydrogen, less helium and trace amounts of lithium. Producing copious hydrogen is a propitious start en route to water, but what about the other essential ingredient, oxygen?

hey friend,
the stars, planets etc. are composed of a no. of gases like hydrogen , helium , oxygen etc.
we know that in space it becomes hard for air or any gas to stay at specific place because of which it combines with the stars or small pieces of matter present in space as it is solid...
when the gases got combined with each other during a condition of high pressure leading to combination of hydrogen and helium because both of them were highly unstable.. providing us with H20 what we call water commonly
other noble gases did not combine with each other because the conditions were not there for example extremely high temperature, certain pH
hope u get satisfied with my answer :)
P.S it is just a theory..

edit ; it was oxygen and hydrogen
