How water is formed? Explain in a simple and easy way.

Answer:
Water has two chemical components, oxygen and hydrogen, which gives us the formula H2O . (There are various joke names for water on the internet, but if you must name it from the elements, then the only chemically reasonable name would be hydroxic acid. But please don't do that, water is what it is).
The reaction stochiometry formula
2H2+O2→2H2O does not describe how the water is made, such formulas are "mass balance" equations only and say nothing about the process. So 2H2+O2 does not mean that two hydrogen or three oxygen molecules literally come together. In fact the low temperature combustion of hydrogen with oxygen is not a direct reaction at all, and involves the intermediate formation of hydrogen peroxide which then dissociates:
H2+O2⇝H2O2⇝O2+H2O
Now we can turn our attention to the real question, the origins of water.
The hydrogen is mainly leftover from The Archaic Universe. That was too short-lived and cooled too quickly to make heavier atoms other than hydrogen and some helium. The universe was initially structured into areas of matter density that formed galaxies, and star formation initiated in regions of higher density.
Oxygen is produced by stellar nucleosynthesis, mainly by an alpha process (fusion of helium), but it also builds up in the core of massive stars, and when large stars explode, the matter is thrown out into space. We belong to the "local bubble" left by older explosions.
