Mighty lot of free hydrogen and oxygen. Takes two hydrogen and one oxygen to make a molecule of water? Considering the amount of water on Earth, in all forms, where did the gasses come from?

Hydrogen is the most abundant element in the universe. It makes up close to 75% of all matter. With 1 electron and 1 proton, it is the simplest element. Lots and lots of it formed as matter condensed. Same for other elements with low atomic numbers - and oxygen at 8 is pretty low. It is the third most abundant element in the universe. So quite a bit of oxygen also formed.

Lots of hydrogen - lots of oxygen - lots of energy....sounds like a recipe for lots of water.
