It does not seem to fit. Other intelligent beings could not be older than humanity because the planets did not exist until the 4th day of creation, when time began. These beings would not have had the time needed to advance in science to where they would be thousands of years ahead of humanity. Also, would God ignore these beings, would Jesus have died for them also ? If humanity had recovered U.F.O’s for more than 70 years why do we not see technology far above what has been seen so far?
Scripture does not mention outer space aliens but there are some who take way out of context certain scriptures that talk about angels and misapplied them to aliens. It is possible that fallen angels impersonate aliens. As of this time I do not subscribe to to idea of aliens but if I am wrong I will accept it and know that God must have created them too.
