Of course, if intelligent beings exist elsewhere, many factors may have prevented them from contacting us, or they may have simply chosen not to do so. Then again, the possibility exists that the extraterrestrials have reached the earth. Most scientists involved in SETI projects, however, have not shown an interest in examining UFO data as a way to test this hypothesis. The study of the UFO phenomenon should not involve the issue of belief. A constant problem ufologists face is ignorance about the subject.
Skeptics often argue against the study of UFOs based upon assumptions unrelated to the evidence.
They assume aliens would not visit the earth in the large numbers that UFO reports suggest or that people see UFOs because of some religious or emotional need. Because scientists do not study UFOs, you might assume that the evidence must be lacking. In practical terms, scientists generally study topics that are academically acceptable, have an abundance of data, and can attract funding from government and private sources.
