Maybe
I'm not familiar with any religion other than 'Heaven's Gate' cult and 'Scientology' that promote a belief in extra terrestrials. Some religions espouse one God while others have gods for all occasions. Except for the two examples (maybe more), creation is Earth centered.
There is a desire or even longing for life to exist somewhere out there in the stars. I don't know why this is but I guess It's not much different than the desire for an afterlife.
At least with ETI, the belief has a chance to be substantiated.
