The other elements are created in the cores of stars via nuclear fusion. The intense gravity and heat fuses hydrogen nuclei together to form helium... Really dense and hot stars (Red Giants) fuse helium and hydrogen into heavier elements. Oxygen, Carbon, Uranium... all of these started out as hydrogen and fused together by stars.
Oxygen is found around a lot too... Everywhere there is water or ice, there is oxygen... So this means Mars... Saturn's moon Titan has a volcano that erupts with liquid water disolved in ammonia!! I think Jupiter's moon Europa has an ice crust.

Lots of hydrogen in the universe. All the stars are made up of hydrogen. Oxygen only on earth. Carbon very few planets.

There are more than 10^80 atoms in the universe. About 75% of these are hydrogen, 25% helium, and only trace amounts of everything else. The great majority of matter in the universe is present in the form of stars.
