When you read about extraterrestrials in the Podesta emails, note from my reading that the Illuminati Luciferian bloodlines believe they are inter-dimensional beings from a higher order trapped on Earth. "Extraterrestrial" is the name they use for themselves.
They believe their purpose here is to raise the pain vibrational level high enough among humans so they can escape back to the 6th of the 7th level that will merge them with the Source.
Total dumb-assed dupes of Satan, but that is what they believe and that is what they're doing.
