Are we alone in the Universe? The scientific evidence and its philosophical implications

The Chair of Harvard's Astronomy Department, Avi Loeb, has argued that Oumuamua, the first interstellar object ever detected passing through the Solar System, may best be explained as a probe from an alien civilization. Should we accept Loeb's argument? How can we assess the likelihood that we are alone in the galaxy or wider universe? What would be the philosophical implications either way? Should we expect extra-terrestrial life to have any significant similarities with terrestrial life, and what might extra-terrestrial contact result in? This course will address these and related questions relevant to the species-defining issue of whether we are alone in the universe.
