You don't have to know how to spell "tree" to know what one is... and thinking you do is holding up science teaching in many, many schools.
spelling water -- first grade
knowing what molecules and atoms were, and water as an easy initial example ... second grade.
Further understanding ... continued until high school when we learned about orbitals and such, College when we really got into the "nitty gritty" about wave versus particle theories (both at once).

How can two very explosive gasses make up water?
Funnily enough, oxygen isn't explosive, just flammable. And when hydrogen explodes, it reacts with the oxygen around it (heat is the catalyst, you see) and creates water.
Oxygen isn't really flammable, it is a necessary component for flames. Burning is sometimes defined as combining oxygen with anything else.
non-technically (fire fighting) they teach of the "fire triangle"
air + fuel + heat = fire
, they will then need to react to form bonds which will allow them to become stable. This is why they are flamable as many of these reactions produce heat. Water leaves each of the atoms with a full outer shell, making it stable.
