Some people believe that the "Rapture" is an event in which all believers in Jesus Christ as Savior will be instantly "transported" to heaven. Some think that at the moment this occurs, to the unbeliever's eye, it will seem that millions of people disappear simultaneously.
There are different ideas on how people will explain the disappearances. Some think that near the time of the "Rapture" there will be an increase in UFO activity with more credible sightings which may result in some thinking aliens had a hand in the disappearances.
Whether you subscribe to this way of thinking or not, assume for a moment that the "Rapture" is true. What possible explanations do you think people may have?
