Question about the ending in Lord of the Flies (details inside)

On the last scene of the movie/book, a Marine stands on the beach and, seeing and hearing the children screaming and running though the woods with hand made spears asks, “what are you boys doing?” I’m no literary critic but what do You think would have been a more believable remark?
