Many alleged sightings have been made, with about 150 sightings reported every day.  90 to 95 percent of these can be explained as natural or man-made phenomena.  The remaining 5 to 10 percent (8 to 15 reported sightings every day) cannot. Many people report abduction experiences as well. However, these individuals are often influenced by the media's portrayal of aliens in such shows as [[Star Trek]], and may base their reconstructed memories on these mental images.

Many alternative explanations for the abduction phenomena have been put forward by a number of people. Among the most prominent of these is "sleep paralysis," a sleep-related disorder which can induce sensations very similar to those reported in abductions, posited by [[Carl Sagan]], well known for his thoughts on [[extraterrestrial life]]. Many conservative Christians believe that UFOs can be explained by 'false messiahs and false prophecies' as predicted to come by Christ.
