A Close Encounter of the fifth kind is a close encounter of a UFO event that involves direct communication between aliens and humans.[1] This type of close encounter was named by Steven M. Greer's CSETI group and is described as bilateral contact experiences through conscious, voluntary, and proactive human-initiated cooperative communication with extraterrestrial intelligence.
