[ WP ] Humanity is the only race in the galaxy with such a massive lack of common sense that we 're the only species that requires laws to form societies . Other races just form naturally and are shocked when confronted with humanities laws and regulations .

`` I do n't get what you do n't understand!'' The human nearly shouted. We had hit a rather appalling hitch in our interaction. 
 
 `` Look out the window. Do you see those lights, the green ones? Watch them change. Those vehicles would constantly run into each other if the lights were n't there to tell them when to stop and go. Without...'' His voice faded as I noticed something that had eluded our preliminary scans. 
 
 `` Wait,'' my universal translator doing the heavy lifting for me, `` what do those vehicles run on?'' 
 
 `` Gasoline. It's a derivative of a fossil fuel called oil.'' Another human piped up. The one that had explained various math and science concepts the humans knew to me. I was quite impressed with his knowledge of binary. 
 
 `` Fossil fuel? THOSE ARE COMBUSTION ENGINES?'' My mind was reeling. This ca n't be. They had broadcast signals we were able to intercept *light years* from Earth. 
 
 `` Well yes. We have n't yet perfected a sustainable power source to supplant oil. There are some very promising advances with electricity but-'' I cut him off. `` How long... How long is your recorded history?'' 
 
 The man in charge turned to look at the scientist. `` Uh... About Six thousand years.'' 
 
 There's no way. There's no possible way. Only six thousand Earth years? This ca n't be. We've made a serious blunder contacting the humans. It explains everything, their `` laws'' the many, many languages spoken, the weapons many of them were carrying. This was us Ten thousand years ago. 
 
 But so much more advanced, technologically. What will they be capable of in another hundred years? I tried to recover `` Well, you have nuclear energy, that's certainly more sustainable. Why do n't you use that?'' 
 
 `` Well people are wary of nuclear power.'' 
 
 Oh no. 
 
 `` Why?'' 
 
 `` Because of the bombs.''
