You can't destroy Eru's creation just by entering the world and throw bombs. You can destroy every mountain, every city, everything but not the world itself. Furthermore, you can't kill the Valar, only other Valar could banish a Valar into the void. Middle Earth will never cease to exist unless Eru chooses so.
