The Hopi believer this is the taking of the mass of humanity off the surface of our Mother the Earth. People will willingly get into their craft out of fear that the Earth is ending (a deception and lie) and the promise of "heaven" as an alternative (escaping into the past via space/time - again another deception). The Hopi even mention this in their oral traditions as the "coming of split/time":

'many pahana (Caucasians) will disappear in Time. He will lock his doors and windows and leave his cities empty and without caretakers. The streets will be deserted, the wind will blow and nobody will be in the pahana streets to hear the wind. If there is a field of Corn, one ear of Corn will remain.'
