Extraterrestrial species

So i see there a couple of different :

1 - Either there are no other living creatures out there (wouldn't be a good sign i guess)
2 - They are watching us and decided not to visit a world full of hate and retards
3- They aren't as advanced and can't talk/visit whatever to us.

Your second point reminds me of the movie Arrival, where they come to actually teach us to stop fighting each others.

The 3rd is more likely. You'd need to be able to detect that we exist, to be able to move in space (+ at fast speed) while being able to sustain life on that spaceship, and a good reason to come. Because you would not want to spend most of your ressources just to visit an inhabited planet without knowing how the living creatures there would react, and what you could get from them.
