i think the guy who said Ultraterrestrial beings has it right. maybe they arent from a different part of the universe but a different part of the spectrum that is reality because we only see the sliver that is matter (10% or so) so maybe they can be in any form they please from a faeri to an alien to an angel. i say angel because ive read in many reports that they ask about emotions and free will and isnt that what god created the angels with out. so maybe aliens are Gods observers to this giant experiement that is humanity. oh and by the wayaliens and faeris are said to have the same symptoms
