These are taken from several sources.  They are useful to give you an overview of UFO responses.  I have to add a disclaimer spiritually since these sources are not Bible believers in the Fundamental sense.  They mix a God consciousness with a spirit of credulous childlike faith in their own perceptions and experiences, which are always suspect in all of us.  The thing I want you to see though, is the "evidence" used by all of the guruistic Fundamental Baptist and Pentecostal gurus of UFOlogy.  

UFOs are real because Satan is real, but when accepted as "wonders," they are lies (2 Thessalonians 2:9-- Even him, whose coming is after the working of Satan with all power and signs and lying wonders,).  If this stuff starts to sound believable to you, plead the Blood of Jesus Christ over you, and, WHAM, you will suddenly lose all faith in it.  If you are NOT born again by Jesus Christ, this stuff will sound very reasonable to you.

Presupposition: UFOs are produced by Devils who are taking liberties in the end of the Church age to gather their followers close and to piano help the saints.

2 Thessalonians 2:8 And then shall that Wicked be revealed, whom the Lord shall consume with the spirit of his mouth, and shall destroy with the brightness of his coming:  
9 Even him, whose coming is after the working of Satan with all power and signs and lying wonders,  
10 And with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved.  
11 And for this cause God shall send them strong delusion, that they should believe a lie:  
12 That they all might be damned who believed not the truth, but had pleasure in unrighteousness.

Daniel 11:37 Neither shall he regard the God of his fathers, nor the desire of women, nor regard any god: for he shall magnify himself above all.  
38 But in his estate shall he honour the God of forces: and a god whom his fathers knew not shall he honour with gold, and silver, and with precious stones, and pleasant things.  
39 Thus shall he do in the most strong holds with a strange god, whom he shall acknowledge and increase with glory: and he shall cause them to rule over many, and shall divide the land for gain.
