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).
- In Macross Zero, it's suggested that the natives of Mayan Island in the Pacific worship the Protoculture, now extinct, as divine beings. They were also responsible for the creation of the human race.
- In Spriggan, the Mexican gods (especially Tezcatlipoca) are worshiped as Aztec gods when they first arrived on Earth as Ancient Astronauts.
- Most of the patron-lines in the Uplift universe act like the mythical Progenitors that began the whole uplift tradition were gods. With many interpretations of why they vanished and resulting wars. Some of humanity's worst enemies are those who believe the Progenitors will return to cleanse the galaxy of "impure" species like those uppity wolflings in Earthclan.
- Footfall. The alien Fithp (AKA "Snouts") gained all of their scientific knowledge from artifacts left by the Predecessors, a race that lived on their planet long ago. The Fithp worship the Predecessors as deities, with priests studying the artifacts to gain more information.
- In Grand Central Arena, the Faith worship the Precursors who built the Arena as gods.
- 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.
- In Stargate SG-1 and Stargate Atlantis the Ancients are sometimes considered to be gods. They don't really care that much, however their evil counterparts the Ori demand worship.
- An individual example of this was Knox on Angel, who worshipped the Old Ones and brought about Illyria's resurrection.

- In Myriad Song the Remanence reveres the Syndics and eagerly await their return, seeing how they are ruled by descendants of their genetically modified slave overseers.
- Classic Traveller supplement Alien Module 8 Darrians. The ancestors of the Darrians were moved from Earth to their new planet by an Ancient named Onsorik. Not surprisingly they worshipped him as a god and passed down legends about him to their descendants.
- Hollow Earth Expedition. Thousands of years ago the Atlanteans were masters of the Earth. They reached heights of technology so advanced that modern day scientists can't understand them. Before they disappeared, their human followers considered them to be gods and built temples to worship them.
- The Covenant of the Halo franchise are a coalition of species united in worship of the Forerunners. Too bad that humans unintentionally defiled some holy Forerunner ex-colonies.
- They also mistakenly believe that the Halos will lead them to where the Forerunners left to. Instead of being superweapons that can destroy all complex life in the galaxy.
- In Sword of the Stars the Zuul worship their Suul'ka creators and are determined to find them in Lords of Winter they succeed

- StarCraft: The Xel'Naga began a series of experiment on the Protoss to speed their development, eventually revealing themselves to their subjects.

- Jak and Daxter: The Precursors are revered as divine god-like beings by many of the inhabitants of Jak and Daxter's universe. This makes The Reveal of them as Ottsels, like Daxter and latter Veger after being "blessed with the gift of evolution", quite surprising and humorous.
