THE GREAT DISAPPEARANCE -

There is a tradition among some Evangelical Christians of an event to happen in the future called the rapture. This is the catching away of the saints to heaven just before the time of the Great Tribulation. 1 Thessalonians 4:16, 17

16 For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first:
17 Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord.

Now this is foreshadowed in the Old Testament (I'll get to where the UFO conspiracy might be involved) with Enoch, the man who walked with God and was no more, in Genesis 5. Then again it is seen in Elijah, the prophet who was taken to heaven on a whirlwind. That's right! Alive and taken into the Heaven (special deal here). It has another semblance in the happening just after the crucifixion of Christ:

Matthew 27:
52 And the graves were opened; and many bodies of the saints which slept arose,
53 And came out of the graves after his resurrection, and went into the holy city, and appeared unto many.

Where did these saints go? Did they live out the rest of their lives on earth? NOPE! When Christ ascended he took them with him! Acts 1! WHOOEE!

Now for the weird part; how do you think they'll explain such thing? UFO's are a GREAT candidate for that idea!
