This is a classic from 1956! The entire UFO phenomenon (beginning with Roswell in 1948) is cleverly crafted by the "god of this world", so that when the upcoming Rapture happens, there will be a "logical" counterfeit explanation, ignoring the Rapture. Aliens removing people from the earth! The Rapture will be by and large rejected as an explanation, but it is in Scripture in both the New and Old Testaments as an event that happens in the End Times! We live in times of extremely great deception in many areas!
P.S. These early science fiction movies also happened to be quite corny! But fairly funny to watch! Enjoy should you watch the movie! Get some popcorn!
