Science (Astronomy): What is the possibility of the existence of aliens?

When you are teaching a unit on Astronomy, inevitably you are going to get into a discussion with students on the possibility of life outside of our own solar system.  In this Veritasium video, Veritasium asks people on the street whether or not they believe in aliens.  The responses are great to listen to.  The discussion of the video is more about the knowledge of how vast a galaxy really is.  If people understood how far a light year actually is, it would be less likely that anybody would believe in the alien types that visit the Earth.  In the video they show a scientist who has discovered 8 exo-planets himself and his ideas on the concept of extraterrestrial life.  Also part of the video they discuss a few methods of how scientists are discovering these exo-planets.
