It would be nice if they could leave religion mostly out of it, at least for humans. Show that we have moved so far that what anyone believes is up to them, provided it doesn't hurt others, and that proselytizing in any form (including proselytizing for atheism!) is if not banned, at least heavily discouraged.
The best sci-fi take on alien religions affecting humanity IMO is the Babylon 5 episode Believers. I wish more sci-fi would be so daring.
