I’ve been told, by people who read websites but who never talk to actual Scientologists and don’t know me at all, that they’ve “researched this” and “found out” that no matter what I say I actually believe in aliens.
Some secret “belief in aliens”, “worship of aliens”, or any other accept-the-alien-overlords-into-your-heart story has positively nothing whatsoever to do with my belief system at all.
In 30+ years in Scientology, no Scientologist I’ve ever met, at any point in Scientology from the lowest levels to the top, has ever overtly stated or covertly confided to me a belief in aliens. Nobody has every inferred to me that I should believe in aliens, or that once I get to some certain level, that I’ll now understand that “it’s all about aliens”.
Close friends and family of mine have reached the highest levels possible in Scientology, and have studied all of the upper-level material purportedly containing said information. They also do not believe in aliens.
I’ve done a chronological study of the Scientology theology comprising 18 full books and 200+ lectures. (Watch this video here for a complete summary of each of those materials) Spirituality, how to improve one’s mental state, and greater happiness is what it’s about, not some worship of aliens.

If you yearn for a belief system that centers around aliens, you’ll need to find another one as it’s not Scientology. If you wish to find out more about aliens, I suggest a career at NASA JPL or perhaps SETA, as your search will not be fruitful in Scientology.
There has been a long-running campaign by various bad actors to attempt to trivialize the beliefs of Scientology, to make them seem outlandish or worthy of ridicule, and a seemingly-effective way to do this is to convince people we believe in aliens. However, to this date, the only place you will find this belief of aliens is out on the Internet. If you walk into any Scientology church, and take courses from the earliest beginning courses to the very top, you’ll not every at any point, suddenly realize you believe in aliens. Sorry to disappoint, if that’s what you’re after.
