Shepard: "[The Hanar] worship your people as gods."
Javik (the last Prothean): "Pity we did not teach them to speak better."
So, an untold number of years ago a civilization with incredibly advanced technology arose, then for whatever reason vanished into thin air. But what happens when a younger race comes across their incredibly advanced technology
or other signs of their presence. Often, religion.
If the adherents come across the name of one or more of the Precursors they will specifically invoke those names. And construct a pantheon if they discovered more than one.
Finding the ancient race is a frequent goal of these people, woe betide anyone who gets in their way.
It's not uncommon for such peoples to adopt the tech of their "gods"
Bonus points if the Precursors
actually did create the species that worships them.
If these Ancient beings turn out to be still around Abusive Precursors
tend to use these cults as pawns, if they didn't set them up themselves. Neglectful Precursors
are often somewhat annoyed
by them if they even bother to take notice. While Benevolent Precursors
sometimes set up cults before leaving, then are disgusted by what has become of their followers when they return.
Anime and Manga
- The Saint Church in the Lyrical Nanoha franchise worships the last Saint King of Ancient Belka, a civilization that warred itself into non-existence about a century ago (it would have lasted longer if said King didn't put it out of its misery).

- Discussed via thought experiment in Chariots Of The Gods?. von Daniken postulates a world where much of civilization has been destroyed. The older generation tell stories of how it used to be to their children, who write it down. Each story begins with "My father tells me..." After a few generations the context of "My father tells me..." is lost, and new translations/editions of the collected stories of the fathers use "My father says..." and eventually "Our Father says..." promoting the first generation to virtual (if not actual) godhood.
