Does it ever decompose or turn into something? If no, then theoretically, if we burned all dead bodies for trillions of years, would earth eventually run out of supply because there was only ash left, thus life would end? Sorry if this sounds stupid

Yes. Ash is what remains after you burn someone.
So oxidized stuff, mostly metal oxides.
The carbon is gone as co2 mostly.
Most of those are at least somewhat solvable in water, and so will get washed into the ground and oceans.
Ash is actually a good fertilizer in ways.
