There are many weird creepy aliens wandering around this Earth.

1. Honeybee, of the New Conquerors is a member of the insect/mammal Kith.
2. A member of the Mollusk Men royal family is known to live in New York City.
3. The FBI and CIA frequently make use of the mercenary Blackthorn, member of the steel-skinned Vauvox.
4. Demons and Devils, although technically extra-dimensional in origin, are still aliens.  They trample the Earth all the time, and the devil called Malachi frequently troubles the Western coast of the United States.

At home, there was evidence to suggest that the Tower had been constructed by an alien intelligence, so I'm coming to terms with the huge number of extra-terrestrials here.  However, I'm still skeptical about the "divine" nature of these "demons" and "devils".
