Some linguists believe that dialogue between aliens and humans might not even be possible, pointing towards the fact that humans are unable to communicate with any other species on earth. Linguist Keren Rice posits that basic communication between humans and aliens should be possible, unless "the things that we think are common to languages—situating in time [and] space, talking about participants, etc.—are so radically different that the human language provides no starting point for it."
