Holy....Freaking genius! I don't think I've heard this argument before.
But anyways, for one, any carbon based element is going to be partially flammable. Trees do have a thick bark which helps from some outside elements, but fire quickly can penetrate that. Maybe they're still in the process of becoming fireproof. But you have to remember, evolution is slow, and not perfect.
Also, forest fires are actually a good thing. It removes all the dead underbrush, and makes the land more fertile for tree seedlings to grow. And most firewood and paper that you use come from forest farms where they actually plant MORE trees than they cut down.
You could also ask why humans haven't evolved to be bulletproof, or cancer proof. But sorry, evolution doesn't work that way.
Edit: Even though you're a troll, I'll leave my answer here. Also, die.
