Aliens as you think they are don't exist. There are no little green men (or grey) from outer space.
As I've said dozens of times before. "Aliens" are interdimensional beings otherwise known as fallen angels. And there is no outerspace as you know it because the earth is flat and we live under a firmament. I understand this is difficult for you pea brains to accept with all your programming , brainwashing and wilfull ignorance but it's the truth and you need to accept
The truth hurts.
