"What are those Nogat?"
"Ah, these Sire are what the Earthies call boats."
"Boats, eh? What are they for? Can you eat them?"
"No Sire. Earthies use them to navigate the seas."
"Why? What’s so interesting about endless stretches of boring water?"
"Their seas have fish, Sire."
"Fish, eh? What are they for? Can you eat them?"
"Ah then it all makes sense. They go in the um.. boats to catch the um.. fish so they can eat. Great! These aliens are not so alien after all. So, do you think we can use our space ship to go in the seas to get fish? I’m hungry. And Nogat..."
"Make a note to send some spaceships in to our deep seas. May be there are fish we can eat there too. No one has ever thought of looking. This has certainly been a productive mission."
