Satan knows that the Bible is true, and he knows what is coming, and he knows he is personally going to lose, and he knows when. All of his machinations are simply designed to prevent as many human beings as possible from accepting the gospel of Jesus Christ in the time he has left. All of his plans are focused on this single goal. He knows that born-again Christians are beyond his reach, and that we have this annoying habit of witnessing to the unsaved. He therefore places a very high priority on killing off as many of us as he can, as soon as he can.
The Bible tells us that Satan's fallen angels were responsible for corrupting ALL of humanity prior to the Great Flood, except for Noah and his family. They seem to have accomplished this by assuming human bodies, and having sexual intercourse with human females. Satan knew that, according to God's promise to Eve that her seed would destroy Satan, his only chance to avert his own destruction lay in corrupting her seed, since the Messiah could not be born of such. The Messiah's genealogy would have to be pure, all the way back to Seth.
He also knows that, according to the Bible, he will be cast down to the earth, and that he will then have unobstructed access to the spirits of large numbers of human beings for the first time since before the flood. When that happens, near the mid-point of the seven-year period called the Tribulation, all of those poor souls who will have accepted the "mark of the beast" will be spiritually defenseless against demonic possession. Satan's forces will use these possessed individuals to kill the "Two Witnesses" (the Church and true Israel) during the last half of Daniel's Seventieth Week. In the meantime, Satan is setting the stage for all this.
UFO's have been reported for many centuries, but only in this century has the phenomenon been studied and analyzed in depth by a variety of different disciplines. The military has its own reasons for trying to find out what they are, and they have come to their own conclusions, whatever they may be. New Age types believe, because it feeds into their world view, that these are superior beings from other planets, another dimension, or whatever. Unfortunately, many Bible-believing Christians have been sucked into this belief system, perhaps due to unwillingness on the part of pastors or Christian authors to comment on these strange phenomena.
