Hi there, remember the aliens that talk at the ending of the film...a small one and a big one, and that they seem to be talking about "the meaning of life"?
To add on to what jcgamer107 posted, the language is intentionally incomprehensible because the meaning of life is incomprehensible.Just when you're about to hear the answer, the language you recognize switches to the unrecognizable and undecodable.No matter how close you think you get to obtaining life's answers, the answers elude you, ever more unobtainable and unfathomable.
