There is a ton of information on the internet about UFOs and extraterrestrials. Much of it is bizarre, making wild unproven assertions about things like presidential candidates being aliens. There are also many cynics who debunk all claims of extraterrestrial life without examining potential evidence.
At the same time, there’s still a huge public interest in the possibility of extraterrestrial life. If you look at the all-time box office earnings, a lot of films about aliens have done really well: Avatar, Star Wars, E.T., Transformers, Independence Day, Star Trek, Men in Black, etc. News about extraterrestrial life also seems to be consistently popular whenever a well-known scientist like Stephen Hawking shares his thoughts on the subject.
