"If our society seems more nihilistic than that of previous eras, perhaps this is simply a sign of our maturity as a sentient species. As our collective consciousness expands beyond a crucial point, we are at last ready to accept life's fundamental truth: That life's only purpose is life itself."
In Legend of Galactic Heroes, religious beliefs are close to non-existent, which is explained as a result of people becoming disillusioned over religion after a nuclear holocaust mentioned in the backstory. The only organised religion present in the series, the Terraist Church, turns out to be a Path of Inspiration which aims to revive Earth's past glory through subversive actions such as assassinating key figures of the galaxy.
Religion is rarely mentioned in the classic Universal Century Gundam. There is still room from any number of fringe cults but these mostly have political ulterior motives, such as the Zanscare Empire in Mobile Suit Victory Gundam.
In Warren Ellis' Supergod, faith is stated to be a biological flaw in human neurology that enables group behavior without the enlightened self-interest that should preclude it; a "narcotic response" to the concept of a higher power. This means most of us will follow leaders based on their ability to evoke that response rather than their ability to encourage survival. It also means that most of us would be quite willing to surrender our free will to powerful forces that don't even see us as bacteria. You can guess how that turns out.
Harmony Theory: Inverted. Modern Equestria is both more scientificlly advanced and more religious than Rainbow is used to. She considers it strange to think of the alicorns as gods or to pray to them. Twinkle Shine lampshades how this is different from what her class might expect.
In Star Wars: A New Hope, where an Imperial Officer implies that the Force is regarded as "ancient mythology" in a pejorative sense:
Darth Vader: Don't be too proud of this technological terror you've constructed. The ability to destroy a planet is insignificant next to the power of the Force.
Admiral Motti: Don't try to frighten us with your sorcerous ways, Lord Vader. Your sad devotion to that ancient religion has not helped you conjure up the stolen data tapes, or given you clairvoyance enough to find the rebels' hidden fortress ...
Darth Vader: I find your lack of faith disturbing.
A sadly-ignored plot point in Plan 9 from Outer Space is that the alien invaders "also think of God" (implying they are not only religious but Christian), while the humans expected otherwise.
Stanislaw Lem's Solaris lapsed into painfulness: the protagonist's brooding about how humanity has not improved in any way is in the immediate company of the protagonist's brooding about how humanity has outgrown any foolish notions of God. However, in Lem's Fiasco, the crew of the expedition that tries to contact with an alien race, includes a priest, who's portrayed positively. This is standard with Lem, really. He was writing in Soviet Poland, and one of his very first books was Soviet propaganda. Solaris was intended more to be about how humanity would react to meeting a very, very alien alien. Or possibly how they would take finding out that God is surprised to know we exist if you must make it symbolic. Just remember that Lem knowingly set out to use certain of the alien tropes as anvil targets...
In 3001: The Final Odyssey, the Earth of the titular year has long since abandoned religion. It's said that everyone is either a theist or a deist, as defined: the theists say there's at least one god and the deists say there's at most one god.
The Light of Other Days, co-written with Stephen Baxter, had a device that could see into the past; among others, Moses didn't exist, having been a merger of several different historical personages. Jesus did, but was just a good person who inspired people, rather than a miracle-maker.
Childhood's End, similar to the above example, the visitors give humans a device to see into the past. Apparently, every religion save Buddhism becomes discredited. Also, the visitors look like stereotypical devils; it turns out they are heralds of a change so monumental it echoes back through human history, causing the "devil" image in the first place.
The Fountains of Paradise, about the building of a Space Elevator, in which humanity's First Contact with an alien AI had the AI disprove the works of Thomas Aquinas, and possibly Christianity itself(!). And that was all in the exposition. There is one religion left practicing (a Buddhist-type), but it leaves its monastery when the yellow butterflies reach the top of the hill it's on, simply because they were prophesied to do it. It is mentioned that Vatican still exists as a centre of Catholicism, but suffers from severe financial troubles, implying that the number of practicing Catholics is minuscule.
The closing stories in the Rama books, on which Clarke either collaborated or wrote himself, subvert this. The setting has humanity already in religious decline by default, however the very end of the series presents not only possible evidence for the existence of a divine being such as God, but an explanation for his laissez faire attitude to dealing with his creation.
In the advanced cultures of Isaac Asimov's Foundation trilogy most of the main characters are supposedly atheists, and the leaders of Terminus certainly are, but outside Terminus religion itself survives, even if it's used as a tool of control at times. Over time though, Hari Seldon assumed an almost religious significance to the people of Foundation, to the point where many of them had a decidedly irrational belief in the infallibility of his predictions.
The Second Foundation trilogy (written by modern authors) portray the different aspects of Robot philosophy (Asimov linked his Robots and Foundation series in later books) as being akin to religions, including "Calvinists" (which for religious scholars is wonderful as these are the conservative/catholic analogues), and several other sects who have their own interpretations of the body of doctrine that is the Laws of Robotics.
His "Nightfall" is even more interesting. The scientists had worked out the cause of the periodic devastation and the things called "stars," and the religious fanatics were deeply offended — and also had a much better idea than the scientists how serious the matter was.
Asimov also played with religion in some of his robot stories, including one where a robot that was activated on a space station believed the station's machinery was a god, called it "the Master," and believed Earth was a religious fiction designed for the small-minded humans.
In The Culture novels, the Culture looks at religion as a delusion which you should be sympathetic about. This viewpoint runs into trouble in Look To Windward, where the "enlightened" races are irritated and nonplussed that whether or not the Chelgrian heaven existed before, it demonstrably exists NOW.
Even this concept is played with in Surface Detail. Due to mind state copying technology and sophisticated virtual reality environments, it is now possible to make any number of afterlives as indistinguishable virtual reality simulations. Hell (or it's closest equivalent for each religion) is the most commonly created. It proves to be a contentious issue in galactic politics; with the Culture not taking an active role. Initially...
The Algebraist features a future religion that actually fits in a science fiction setting, the dogma is that the universe is a simulation and the goal is to end the simulation by getting enough of the participants in the simulation to realize they are in one. The main character of The Algebraist seems sceptical of this religion, though. The simulation hypothesis is also brought up in the Culture novel Matter, without a religion surrounding it. See Simulation hypothesis for the real-life example.
Alfred Bester's The Stars My Destination didn't explicitly say that all religion was outmoded in its society, but Christianity was illegal, and pictures of nuns praying was considered equivalent to pornography.
A Case Of Conscience toys with this, which features a totally agnostic if not atheistic alien race that also live in a perfect world and society, faced against a bombed-out, nuclear-fried, and heavily Catholic Christian human race. The priest included in the first contact mission considered that society a danger to humanity precisely because it was a rationalistic atheistic utopia; unfortunately, he'd already befriended one of those people before he made the decision. The alien world is blown up by the latter either using the wrong space telescope or due to an exorcism.
Inverted wholly by A Canticle For Leibowitz, wherein pre-Vatican II Roman Catholicism is the only thing that keeps western civilization intact After the End, and the resurgence of secularism is what leads to a second global conflict.
It's also deconstructed because it's implied that post-Deluge humanity was no more religious than they were before, whether by mere ignorance or secularization.
Giants Star by James P. Hogan has a particularly fierce instance: the protagonists deduce the existence of an alien Ancient Conspiracy to suppress human progress as a reasonably parsimonious explanation for the continued existence of religion in modern times.
A very clever subversion occurs in Robert J. Sawyer's Calculating God. When the first alien craft arrives on Earth, the explorer on board asks not to be taken to our leader but to be taken to our archeologists. Why? The alien is looking for confirmation of the existence of God in our fossil record. Much of the book is a philosophical conversation between a dying, atheist paleontologist and the spiritual, spider-like alien who has come seeking proof of God. Given the facts of the setting, the alien's case is pretty good, and it's atheism that comes off as a silly superstition.
Also touched on in a short story by the same author. Incontrovertible proof of God causes the Catholic church to collapse, as a God who can be proven to exist is incompatible with most theologies.
Anne McCaffrey's Pern is a world without religion. The expressions "Jays" and "by all that's holy" are still in use, but only as swears.
Her Talents series plays this mostly straight. Those few protagonists who espouse a belief in a higher power are, at most, vaguely Deist. Those who are openly devout are almost always portrayed as mentally unstable troublemakers. Organized religious populations are shunted to backwater worlds where "the harm they can do is minimized" (or words to that effect).
Played straight by the Edenists and averted by the Kulu Kingdom in Peter F. Hamilton's (sci-fi) Night's Dawn Trilogy. They are the two biggest players and the two biggest rivals in the Confederation — the former are all atheists and the latter staunchly Christian. However, the Edenists' philosophy and way of life lead to the closest thing to paradise as you can get, and they're also the only human civilization able to fully resist the possessed...
Also, in Hamilton's Commonwealth Saga, religion is for the most part "weddings and funerals" only. However, in the distant sequels of the void trilogy, a massive religious pilgrimage is the source of the main conflict of the stories.
Neal Stephenson's Anathem features a world in which a group of secular monks wall themselves away from society and study pure logic, science, philosophy and art. Although they are not officially atheistic, few members hold onto any religious beliefs. In the outside world, religions rise and fall unnoticed. While venturing in the outside world, monks can quickly reduce any religion they encounter into one of a number of basic categories so that they can avoid causing offense. Religious non-monks are mostly presented as morons, while the brightest are good enough that they aren't completely humiliated when they try to debate with a monk.
Subverted in Robert Zubrin's The Holy Land. The aliens regard Christianity as primitive, bizarre, contradictory, and dub it "anti-rational", not being particularly impressed by the fanaticism and terrorism it is used to inspire. Meanwhile, they worship Minerva and/or Hera and/or Aphrodite, have fought wars over the different interpretations of their religion, debate theology (including strict monotheism versus a triune goddess), call each other heretics, and take the occasional strong moral stand based purely on their religious faith. Less of a Take That to organized religion than Humans Are Bastards.
Sort of both used and averted in the Humanx Commonwealth novels, where humans and thranx and several other species look to the United Church for guidance. It's a synthesis of the basic ethical tenets which all humanx religions share, shorn of world- or culture-specific trappings that would fall under this trope's "superstition" label. Essentially, Unitarianism's gone multispecies: they don't attempt to define or disavow a Higher Power; they just agree that if there is such a thing, this is how he/she/it/they would surely want folks to live, and if there isn't, it's still good to live that way.
In the Uglies series, the people of the future sarcastically refer to gods as "invisible superheroes in the sky". There are some groups that try to bring religion back, but it isn't catching on. In all, the books don't pay very much attention to this, and it's mostly a detail to help show how different society has become since our time.
Roger Zelazny enjoyed making far-far-far-future societies where humans had become Sufficiently Advanced Aliens and taken on the roles and power of ancient gods. In Creatures Of Light And Darkness, they had taken on the personae of Ancient Egyptian gods (including managing afterlives). But one of the most prominent characters was Madrak the Mighty, a warrior-priest "of the non-theistic, non-sectarian sort", whose personal religion was based on an agnostic's deity (another character referred to him as a "holy ambulance-chaser"). When Set the Destroyer pointed out to him that Madrak had just aided in the destruction of the Nameless, an Eldritch Abomination from beyond the universe, which perfectly fit the definition of Madrak's agnostic God, the idea that his god existed - and he profited by Its death - made him suffer a crisis of faith.
John C. Wright's The Golden Oecumene never says anything one way or the other about religion, but it's somewhat odd that in a setting where characters are defined heavily by their philosophical beliefs, the only person who engages in any form of worship or mysticism is a bit character whose philosophy is never explained.
In Suzanne Collins' The Hunger Games there's no mention of religion in any of the trilogy, and even the word count of religion based words is quite low.
May be a subversion because this does not stop the futuristic country of Panem from being no more morally 'mature' or generally enlightened than it's predecessors. In fact, the trilogy is full of comparisons to Ancient Rome and modern consumer society.
In Divergent it is implied that the Abnegation faction (a faction of society that lives much like the Amish) is the only section of society that still believes in God. However, its sequel Insurgent shows that the Amity Faction practices some sort of naturalistic religion.
In an episode of Star Trek: The Original Series, Kirk tells Apollo (or at least a being who claims to be Apollo) the following: "Mankind has no need for gods. We find the one quite adequate." Exactly whether he's claiming everyone follows a generic monotheistic religion or that everyone has just given up polytheism is unclear; probably the former, knowing the probable standards of NBC and society at the time. Kirk also reveals a more spiritual side at the end of the episode when he tells Bones "They gave us so much...would it have hurt us to burn just a few laurel leaves?"
Robert Justman has confirmed that the line "We find the One quite adequate" was required by NBC's Broadcast Standards.
The Klingons are stated to have once had gods, but their distant ancestors killed them all off because the gods proved to be more trouble than they were worth. In spite of this, they have an underworld ruled by "Fekh'lar." One episode of The Next Generation deals with Kahless, a divine, Christ-like ancestor figure in Klingon history. There is a shrine of Klingon priests who await the return of Kahless and Worf has had spiritual visions of Kahless speaking to him in the past. Generally, their faith in Kahless is treated in a positive light.
In "Day of the Dove", Kirk tells Kang, "Go to the Devil!" Kang replies, "We [Klingons] have no Devil... but we are very familiar with the habits of yours." Cue use of torture.
The most Anviliciously atheistic Star Trek ever got was the third season TNG episode, "Who Watches the Watchers"; a group of Federation scientists are using holographic technology to watch a primitive Vulcanoid culture that has apparently abandoned religion. The Federation equipment breaks down, revealing their existence and "magical powers" to the locals, one of whom declares they must be gods and tries to restart the Old Time Religions. Picard takes another local up and explains that the Federation are merely Sufficiently Advanced Aliens, not gods. The episode then goes into Author Filibuster mode; the time humans had religions of any sort is referred to as "the dark ages of superstition and ignorance and fear." Afterward, an away team goes down to the planet to explain how irrational it is to believe in gods because they never show up or tell believers what they want, and that believers are left putting their faith in what other mortals tell them.
In "Where Silence Has Lease" Picard is asked by Data about death; interestingly his philosophical answer seems to hint that while he isn't personally religious he seems to have equal problems with a purely atheistic view.
Deep Space Nine is a 7 year mix of affirmations and aversion/subversions of this Trope. The Commander of the station was declared to be alien Jesus in the first episode, later finding the alien Gods to confirm it, then having visions and becoming a god himself.
In "Dagger of the Mind", and in Star Trek: Generations, it is shown that they still celebrate Christmas and actually call it that, instead of the current contemporary habit of "Holiday Season". Obviously, in the 23rd century, regardless of the actual Christian content observed, they have removed all of the current commercialism from the holiday. In "Data's Day", Data mentions that the Hindu Festival of Lights was still observed.
It's very much worth noting that many Christian viewers never had any problem with the Original Series, because after all, Kirk was running around the universe toppling transparently false gods (including Apollo himself!—while citing the virtues of monotheism both in that episode and in "Bread and Circuses") and that the computers like Landru and Vaal are literally the ultimate form of idolatry, the worship of physical manmade gods. Despite Roddenberry's penchant for Kirk vs. god-thing-of-the-week plots, open hostility to monotheism didn't come to the fore until Next Generation. The closest the original series came to this was probably "Return of the Archons," and even that one ended with Kirk taking down yet another computerized idol.
Some could see Stargate SG-1 as one big Take That against organized religion. The eponymous team spends at least half of the plot convincing primitive groups that their gods are fake and should forget about them, even the ones with the characteristics of actual gods: they are, after all, merely sufficiently advanced aliens posing as gods, either snaky parasites out to exploit mankind or well-meaning Little Gray Guys trying to help. With the Ori, things are more blurry: they actually qualify as gods according to one Real Life religion and would do so in most fantasy series, but writer intent evidently considers them false gods as well.
Many other episodes also reference religion in subtle or not so subtle ways, like The Sentinel, where the Latonans refuse to evacuate in the face of an alien invasion, constantly referencing their "highest law".
Things were handled a little differently in Red Sky. A planet is doomed and the people refuse to leave as they think their death is the will of the gods (specifically the Asgard). While Jack is more than willing to destabilize their belief system, Daniel tells him that while the possible existence of God is not important, the belief is. At the end of the episode, the resolution is deliberately left unclear. It may be that the Asgard fixed the problem, but Daniel wonders if it's possible that a higher power did intervene.
"Icon" featured an incident similar to the aforementioned TNG: "Who Watches the Watchers": the arrival of SG-1 on the planet Tegalus causes a Goa'uld-worshiping extremist faction to gain in popularity, eventually starting a civil war that aggravates a cold war. Difference is, the SGC views it as a purely military/political problem that's keeping them from rescuing Daniel, who was trapped on Tegalus by the war.
Despite the break with ancient Egyptian, Greek, and Roman religions, the show makes clear exceptions in the earlier seasons for religions that are currently mainstream. The episode "Demons" features a planet of Christian-ish people where the goa'uld in question is pretending to be Satan rather than God. The episode comes across as very church-positive, even having Teal'c mentioning that he does not believe any Goa'uld is capable of the "kindness expressed in your Bible."
Stargate Atlantis has plenty of Take That moments against religion, like "Poisoning the Well", where the scientific search for a Wraith immunity drug has become a religion, with libraries of knowledge as a church analogue and a famous scientist's lab notes are a sort of holy text. The real clincher is the population's eagerness to take the unsafe product, even when they know exactly how unsafe it is.
Another episode has one of those weird unclassifiables in the form of "Sanctuary". There, they find an incredibly primitive world untouched by the Wraith, whose inhabitants lead idyllic lives, all of which they attribute to their Goddess, Athar. Said God, it turns out, is actually an ascended being that takes mortal form to serve as Athar's high priestess. So while they are being deceived, they also really ARE protected and cared for by a nigh-omnipotent being.
Which runs straight into Fan Dumb, as it's not the first time in The Verse a character's faith was treated positively. Look no further than Stargate SG-1 season three's "Demons," where a junior Space Catholic priest on the medieval planet stands up to a Goa'uld-infested Unas with the line, "My God is with me, always."
The whole point with the Ori gets a lot of flip-flopping; after a few episodes of dealing with ridiculously headstrong groups, the team basically settles on "Just because they're powerful enough to claim godhood, doesn't mean you should actually worship them!"
The Twilight Zone TOS episode "The Obsolete Man" was set in a future society where religion had been outlawed. Only one man still believed in God, and was sentenced to death for being obsolete. He was given the choice of ways to die. He chose to die by bomb on live television. The high official who sentenced him to death came to speak with him, and was informed that the door was locked. He began to panic, and shouted, "In the name of God, let me out!" The condemned man did let him out — in the name of God. The final scene was of the official being sentenced to death... for being obsolete.
During Russell T Davies' run on Doctor Who, there was little to no mention of magic or religion, and when it was it was usually proven to be science based or very vaguely described. In an interview, Davies claimed that he had banned God from the writer's room, wanting to depict a future where religion had just died out. "[R]eligion is banned on Platform One. Yes, I'm deeply atheist. If they haven't reached that point by the Year Five Billion, then I give up! When did the Doctor do that speech about believing in things that are invisible? It's Episode 5, isn't it? That's another bit of atheism chucked in. That's what I believe, so that's what you're going to get. Tough, really. To get rid of those so-called agendas, you've got to get rid of me."
The original series isn't exactly anti-religion, but religion or religious belief are rarely mentioned in any stories explicitly set in humanity's future, and if it is most of the time it's used to control people and/or a Sufficiently Advanced Alien/Eldritch Abomination worshiped as a deity.
The Doctor, one of the oldest, most intelligent and best-traveled beings in the universe more or less says in "The Satan Pit" that he doesn't believe in God or any sort of higher power (or at least he's never run across anything to convince him of the existence of such a power). Granted, his people the Time Lords were so powerful most civilisations in the universe would consider them gods, so he has a very different perspective on the issue compared to most.
Yet in the original series, the whole "Key To Time" story arc, as well as the subsequent story arc with Turlough and the Black Guardian, are pretty clearly a very thinly veiled story of the Doctor getting caught in the middle of a conflict between God and the Devil (there's a bit of obligatory doubletalk about them being embodiments of order and chaos, not that it affects anything). The new series hasn't mentioned the Guardians at all.
Farscape takes an interesting perspective on religion for a sci-fi show: though it doesn't discuss religion extraordinarily often, it does have practitioners of various alien religions among the crew, some of them quite devout. Plus, the show also demonstrates that gods and magic really do exist in their universe, some of them more visible than others - like the Builders that Moya worships. The Peacekeepers, on the other hand, play this trope straight, with an entire episode, "Prayer", devoted to Aeryn recounting the ancient legend of a Sebacean goddess (implying that they no longer believe in gods in the present day) and praying to her for rescue; for added desperation points, Aeryn notes that the reason this particular goddess doesn't have any followers anymore is because she killed them all on a whim.
A sketch on The Kids in the Hall featured a futuristic society that celebrated Bellini Day in which the characters referred to a time period where mankind was so stupid they actually believed in someone named God.
Cthulhu Tech contains a rather bad example. Christianity and Islam are gone; it's not really expounded upon, they're just gone. Presumably, the very real and somewhat provable existence of the old ones made everyone less interested in religions that have a very specific world view that excludes them.
The Tau seem to exhibit divine worship of their Ethereals, but that is more obeisance to their leaders than religion and otherwise have no belief in anything "magical" or "supernatural", including the very real daemons and other things that inhabit the warp. Interestingly, they are by far the most socially and technologically progressive faction in the setting (which, granted, isn't saying much).
The Eldar believe in the existence of their gods and invoke the power of one on a semi-regular basis, but they don't worship them and most of the time they use their names similar to how most humans today use "oh my god". This is because their gods were eaten by a Chaos god and there is no real point to much of their religion anymore. (Except for Cegorach the Laughing God who escaped being consumed, but only the Harlequins worship it.)
Baten Kaitos Origins twists this trope. It starts off with a fairly simple "science = evil" message, but then it turns out that in the distant past people became practically addicted to the supernatural, and so a bunch of siblings in the past decided to try and stop them from being turned into pure magical essence by making a Deal with the Devil to gain even more supernatural powers in order to overcome what they were fighting, but then they all get sealed into the End Magnus from the first game, but then it turns out that the process that gave Sagi the supernatural power of one of the siblings was a scientific one, but he then uses that power to save the world. While getting a boost from the spirits of the dead siblings, no less. In short, rejecting the supernatural and focusing on science - or vice versa - is a Very Bad Thing, and the best way to live is with both in tandem with each other.
Deus Ex Invisible War is a Double Subversion; according to its backstory, the aftermath of Deus Ex led to The Collapse, in which most people had their faith shaken to the point this trope almost got played straight—until The Order popped up, uniting all of the old faiths into one syncretic philosophy. Later, however, it's revealed that The Order is just one of two fronts for the Illuminati, and is part of their method of controlling polar opposites of society.
In Dead Space, the only known religion humans have left is Unitology, which has been extremely corrupted by leaders who demand high "donations" in order to move up in rank and bastardize their founder's idols. As a result, many (even level header and nice ones) are mocked by their atheist co-workers. Of course they just happen to worship something that comes out of H. P. Lovecraft (and odds are, their beliefs are right).
In Metroid Prime 3: Corruption, Samus visits the planet Bryyo, which is covered in the ruins of a golden age. The Reptilicus people there originally had magical powers. Then, some of them learned how to use technology, and they decided that this was cooler than "primitive" magic. The Lords of Science honked off the magic-using mystics, and there was a big magic-vs-technology war that tore the planet apart. Literally. There are bits of the planet that had to be chained to the surface. It could be said that the Lords of Science technically won, because a few of them were able to recognize the planetary damage and stabilize the planet, though it lead to them revealing their secret location, and thus being wiped out by the mystics. Without the Lords of Science, the remaining Reptilicus devolved into (magical) barbarism.
Averted with the Chozo, who made balance between the technological and mystical aspects of their society a priority, so much so that it's almost impossible to tell where the science ends and mysticism begins in their technology. (Indeed, the Chozo actually warned the Science lords that they needed balance between the two. They didn't agree until far too late.)
The University of Planet faction is the ideological antithesis of the Lord's Believers game mechanic wise, but the faction leader Prokhor Zakharov is especially into this trope, as a number of quotes from him for technological advances reveal. According to the prequel short stories, he and Miriam Godwinson (the Lord's Believers faction leader) do not get along well, even back on the UNS Unity.
The Human Hive faction explicitly seeks to invoke this trope. It's faction leader Shen-ji Yang's social experiment, amongst other things, as he seeks to eradicate belief in higher powers and replace it with an atheistic police state (this is his explicit agenda in-game).
Aside from the Lord's Believers, Gaia's Stepdaughters are noted to be a religious society focused on coexisting with nature, the Cult of Planet is obvious, both of the Progenitor factions smack of taking their dogma to the point of religion.
Star Ocean 1 has Ronixis, who claims that humanity has moved beyond religion. However, finding himself in the backwards world of Roak, and confronted with the existence of magic, which he'd hitherto never believed existed, he finds himself re-examining his views. The sequels make clear that magic is nothing more than advanced science, however.
The third game even simultaneously proves that God exists and provides a scientific explanation for the big jerk.
Both played straight and averted in Starcraft universe. Background material mentions that upon taking control of Earth, the United Powers League(later becomes United Earth Directorate) promoted state Atheism, banning or co-opting all religions and exiling or killing those who didn't adhere (alongside political prisoners, cyber-deviants and other undesirables) in an effort to stamp out the things that have divided the human society. As a result, the territories of the UPL/UED are non-religious while the Koprulu Sector is teeming with religious groups ranging from mainstream Christianity to Crystal Dragon Jesus and to even stranger Cults and movements.
The most advanced race in the setting, the Protoss, nearly killed themselves before the religion/social structure of the Khala was established, and while it's lessened in importance with the acceptance of the Dark Templar, it's still hugely important to most of the race.
In BioShock, Andrew Ryan considers religion an obsolete and harmful superstition "people of tomorrow" should have no need for. He strives to eradicate religion in his Objectivist utopia and declares that smuggling religious texts to Rapture is a crime punishable by death. The experiment however goes terribly awry.
Completely skewered in Albion. For starters, while the crew of the Toronto never mention God, a news report from Earth confirms that the Catholic Church at the very least still exists, and is being led by the pope (one called John Paul the twenty-somethingth). The Iskai and Celts living on the planet worship the Goddess Animebona who is in fact the planet itself, and is quite real and alive. Her antithesis, Animenkhna is technically the "god" of Terran humans, being the embodiment of science and all. The actual God is handwaved by the natives as the unknown. Christianity is implied to be an attempt at compromise, that ended up being too irrational for the Terrans and too rational for the Celts.
Both used and averted in the X-Universeaccording to the X-Encyclopedia. About half the Argon consider themselves "spiritual" but don't believe in any particular deity, while most of the rest are atheists. But since they believe in tolerance, the Argon place no stigma on being religious. The Boron have no organized religion and no omnipotent or creator deities, but some believe that after death they will live on in the presence cloud of theAncients. Averted with the theocraticParanids, whose religion permeates every aspect of their lives. The Split are the straightest example, viewing their old religions as primitive superstition. No word on the Teladi or Terrans.
In backstory of Homeworld, the Kharakians near-entirely abandoned religion after generations of religious wars devastated their already small population, part of a unification of the planet's disparate tribes that placed reason and scientific understanding above all else. Religions still existed to some extent, however their few serious adherents were considered delusional at best and dangerous fanatics at worst. That is, until Kharak wasbombed into oblivion; afterwards the survivors experienced a slight resurgence of religious belief, such as the members of Kiith Somtaaw in Cataclysm.
In Mass Effect humans as a whole still follow lots of religions, but space-faring humans don't, with Ashley implying that she's seen as eccentric for even mentioning her religious belief. Meanwhile, the hanar worship the very real (though long extinct) protheans, and the most popular asari religion is revealed to be entirely based upon contact with Protheans by their primitive ancestors, heavily implying that many ancient religions may be the direct result of alien contact, misconstrued or misremembered by the populations they affected. The turians though avert this entirely.
Inverted in the Freespace game mod Blue Planet. A major part of the story is that mysticism and spirituality are creeping back into society, and there exists at least one Sufficiently Advanced Alien race that is heavily spiritual (or at least, expresses themselves in a spiritual manner). The title of the campaign's first release, "Age of Aquarius", references this: it refers to an age in which, realizing that neither religion alone or science alone has all the answers, people turn to a fusion of the two to reach true understanding.
Used but mostly averted in Startopia. An entire race, the Zedem monks, have converted to the same religion and only two of the games nine races don't pop into a temple occasionally. The only exceptions are the hedonistic sirens and the scientific Turakken.
Fallout 3 / Fallout New Vegas: Religion seems to be alive and well in the post war united states, there are several cults and at at least one major religion encountered in the games.
Inverted by Caligula of The Law of Purple; instead of an advanced culture that once had religion but derides it as worthless now, there was almost never any organized religion to speak of and parts of the population are only now discovering it. However, most Caligulians view religious groups as nothing more than cults and consider them highly abnormal.
Inverted in Get Medieval. Our Theology is actually more advanced than the aliens. One of the Alien characters converts to Islam because his society has a caste system and each caste has their own god. As a free slave he finds it's wonderful that everyone is the same before Allah.
In the universe of Dominion And Duchy, a group called the Cathedrum is explicitly compared to the Catholic Church and the Vatican in particular. It is also described as being the oldest group still in existence.
Berandas: Don't you understand? We are the gods' unwanted children. We are the castoffs, the forgotten. And instead of following some doomsday cult, believing ourselves lost and hopeless like the Grey Cult, or clinging to some decayed bloodline like the Crimson Coalition, we will stand and fight for humanity! The gods don't like our choice of allies, our rising technology? They can burn for all I care, they have never helped us.
Parodiedrather savagely in the South Park episodes "Go, God, Go" and "Go, God, Go Part XII." Cartman awakens in a Hollywood Atheist future where Atheism has replaced religion. Religious factionalism and conflict have been replaced by equally trivial Atheistic factionalism and conflict. People shout things like, "Hail science," "science dammit", and "Science H. Logic!" instead of their religious equivalents. Ultimately the episode is about how atheists are just as susceptible to stupidity as the followers of any religion.
In an episode of Family Guy a lack of religion allows the U.S. to progress technologically by a thousand years, though the arts had stagnated for a similar amount of time.
Similarly, one episode of American Dad is set in 2045, with the present referred to as "when people still believed in The Bible."
In Justice League; Hawkgirl comes from an advanced alien civilization which gave up religion eons ago (because their god was an Eldritch Abomination who demanded their souls in sacrifice), but after a certain episode she comes to believe that there is... something good... out there.
Subverted in an episode of Batman Beyond. The kids at Terry's school think it's haunted when strange things start happening. When Terry discusses this with Bruce, this exchange happens:
Bruce Wayne: These people believe everything they can't explain is magic.
Terry: Naturally, you don't believe in that sort of thing.
Bruce Wayne: Of course I do. I've seen it all, demons, witch boys, immortals, zombies, but this thing ... I dunno, it just feels so ... so high school.
Jean Delumeau narrates in his Sin and Fear: The Emergence of the Western Guilt Culture, 13th-18th Centuries that his trope was one of the objectives of the Inquisition. There were several regulations against practices that were considered superstitious, like usage of amulets and anything magic-related, so much that, in trope terms, they were enforcing that Religion IsNOT Magic.
Go to any "Stupid things you believed as a kid" thread on the internet. Inevitably, someone will mentionGod or religion.
State atheism is an attempt to invoke this trope, which seems to lead to a considerable amount of Utopia Justifies the Means. Since Karl Marx viewed religion as a tool of the bourgeoisie, communist countries have done this as a matter of course. It tends to end up as replacing the worship of a god with the worship of the country's dictator.
Over the course of the past century some countries have seen a rise in their atheist and non-religious populations—in the United States it's risen from 2 to 15 percent—but this is subverted by some of the countries in which state atheism was practiced, such as Russia. The Soviet Union tried multiple times to invoke this trope through anti-religious campaigns, and by 1982 only 20% of Russians actively practiced religion, with a third declaring themselves atheist or non-religious. A few decades after the fall of the Soviet Union, a 2012 survey found that only 13% of Russians identify as atheists or non-religious.
