Erich von Däniken: Erich Anton Paul von Däniken ( ; ] ; born 14 April 1935) is a Swiss author of several books which make claims about extraterrestrial influences on early human culture, including the best-selling "Chariots of the Gods?

The ideas put forth in his books are rejected by a majority of scientists and academics, who categorize his work as pseudohistory, pseudoarchaeology, and pseudoscience.

Close encounter: In ufology, a close encounter is an event in which a person witnesses an unidentified flying object.  This terminology and the system of classification behind it was started by astronomer and UFO researcher J. Allen Hynek, and was first suggested in his 1972 book "The UFO Experience: A Scientific Inquiry".  He introduced the first three kinds of encounters; more sub-types of close encounters were later added by others, but these additional categories are not universally accepted by UFO researchers, mainly because they depart from the scientific rigor that Hynek aimed to bring to ufology.
