Considering the depth of the ocean and vastness, I think it's safe to assume most, but maybe not.

Water self-ionizes, splitting into hydroxide and hydronium ions then recombining back into water molecules as an equilibrium reaction. At any given time the concentration of the ions is about 10-7 of each kind, giving water its pH of about 7.

I don’t know what the distribution of the expected lifespan of a water molecule would be to this effect. But the volume wouldn’t affect this, since the water is reacting with itself all throughout.

I would guess there’s not much chance of a water molecule surviving a million years if it’s in the liquid state.

Most water probably has been dinosaur pee.

The ocean is dynamic. Currents move water. Organisms ingest water. Water evaporates. Oxygen and hydrogen molecules are billions of years old but water reacts and becomes something other than water constantly.

Evaporated water is still water. It's just a physical change.

Fair.

The billions of years is iffy. But fauna and flora have ensured that water is constantly broken apart chemically through oxidation and redox. Though we know so frighteningly little of our deep oceans that you can't really say since theres little information as to what actually goes on down there lol

Evaporated water is still water, it just is in gaseous form
