Hydrogen [1.] was originally produced in the Big Bang and is found everywhere in the Universe. Oxygen [2.] is made in stars and dispersed out into the Universe in events such as supernova explosions. The two elements mix in star-forming clouds [3.] and form large amounts of water [H2O]. The molecules of water leave the clouds and end up in many different places [4.] - comets, planets, the centres of galaxies...
When the newly-born stars become old more oxygen is made available to the cosmic water factory.
