Echo and Thunder proves there is a dome above us
Thunder and Echo both won't work without hitting a solid object, so the firmament being a container and a solid object is perfect for Thunder and the echo, in which this proves the existence of the firmament above us. this cannot work on the globe model because in that model there is a vacuum called "space" above earth so in common sense non of this would work.
