Alien

An alien is a person who is of another family, race, nation or planet than the people among whom he or she lives. Alien can also mean someone from outer space, and this is often the image that one conjures in ones mind when one thinks about the word Alien. Aliens in this sense exist only in fiction, though no one knows whether other races have been created by other Gods on other planetary systems.

Every star ,planet, galaxy, and system, most of which we can't even see has been created by God.

Jesus Christ is His ONLY son. HE sent Jesus to earth for us. As the ONLY creator, then, God would be responsible for any ALIENS that exist. 

Given that aliens exist, they would be subject to sin, and so God would have to do something about it as he has done for us. Assuming He would use the same method as on Earth, he would have to sacrifice his only son, Jesus, multiple times.

The possiblity of life on other planets is hinted at in Moses 1:6 "And worlds without number have I created; and I also created them for mine own purpose; and by the Son I created them, which is mine Only Begotten.
