I believe that aliens are not who they say they are and they have a malevolent agenda. I think that aliens are not aliens but maybe are demons or followers of Satan.
There is a 20 year scientific study about the alien pheonomon and they have found that there are many similiarites to aliens and demons. For example, they appear to have supernatural abilities, like walking through walls, shapeshifting, materialization and dematerializion and how thier craft and abilities defy our understanding of physics.
Aliens have been known to do horrible things against humans without thier consent such as remove egg and sperm from people and implant them in women after they have been altered with alien dna.
They have told people different reasons of why they are here and who they are throughout the ages. Now that we are in a scientific age they refer to themselves as aliens. But in ancient history sometimes they refered to themselves as fairies, angels, gods, demons…so they are deceptive.
Beings similar to aliens have been reported seen in occult and witchcraft rituals. Allister Crowly even reported to have been in contact with an entity that was similar in apperance to aliens.
There are many evident similiarities between the alien abduction and sleep paralysis cases. Details in the accounts are similiar in what the victims experienced and although they might be different they are seemed to be both stoped the same way, which has been by calling out to Jesus.
I asked myself if God made another species of life like humans why would God create man in his image but not them and why did Jesus die on Earth as a human, it didnt make sense.
The Bible and the Book of Enoch does talk about Satan, fallen angels and the watchers. And how some of the fallen angels did go to Earth, decieved people and impregnated women which resulted in giants. If you do research skeletons of giants have been found around the world and many stories of giants from different cultures exist too. So it maybe that it is the force behind the alien abduction cases that report that they are creating a alien/human hybrids are fallen angels that have the same agenda.
Many people have reported that the grey aliens are not the ones who are in control but they work for a reptilian race of aliens reffered to as Reptilians. The devil has been reffered to as a serpent.
There is a religion called Rael which teaches that aliens created the Earth. The founder believes that he has been in contact and enlightened by aliens and teaches a worldview which opposes many Christian ideologies. Also the secrets of Scientology such as the belief of Xenu.
So may it be that the aliens are really under the control of the evil one?
