What are the 4 types of alien encounters?

(Reality)

1) Fictional

2) Imaginary

3) Fraudulent

4) Mistaken

(Fakery)

1) Sighting-- aliens, pink elephants, Elvis, etc.

2) Evidence-- Since anecdotes never become evidence, even in vast numbers, there is none.

3) Contact-- none known and proven to have occurred. The White House lawn is not that hard to find, so if there are aliens attempting contact, they are completely incompetent.

3) Abduction-- Also, none. To date, no one claiming abduction has sworn out a warrant for these person or persons unknown. Coincidentally, lying to the FBI is a good way to get sent to the pokey. One might logically conclude the "witnesses" know they are lying.

Or, on the less scrupulously skeptical side, see below:

----------------------------------

1) Sighting- An encounter with a UFO

2) Evidence- Where you can find clues that an alien/UFO has been to a place. Example: Crop Circles

3) Contact- When you meet an alien face to face or see them from afar.

3) Abduction- Is when some one is temporarily, or permanently, captured by an extraterrestrial being
