Water can be formed in a few different ways. Typically it is formed through combustion. When hydrocarbons burn in oxygen they release CO2 and H2O. This is included in metabolic combustion too. When our cells burn carbohydrates it forms CO2 and H2O.

Burning Hydrogen gas with Oxygen gas will make pure water, 2H2 (g) = O2 (g) --> 2H2O (g) This reaction is quite spontaneous (and explosive) one it has been ignited. This is the reverse process of splitting water apart [through elelctrolysis] into H2 and O2. Many other chemical reactions produce water as a product. Similar to burning Hydrogen gas, burning Hydrocarons (example, Methane or Octane) also produced water [amongst other things]. Another exakmple would be a reaction between baking soda and vinegar. The reaction produces Carbonic acid (H2CO3) which quickly decomposes into Carbon Dioxide (bubbles) and water
