->'''Cassie:''' Have you ever thought about all the weird shit that people say goes on? Like aliens and Bigfoot and how many stories are there? But it only takes for one of them to be true and everything is different. Like... everything we logically believe is up for grabs.
->'''Andrew:''' Okay. But I'm thinking "Man marries Werewolf" probably isn't the one.
-->-- ''[[http://www.youtube.com/watch?v=S4_paHTRdHQ Fuel]]''

This is a trope with two opposing halves that explode on contact, much like matter and antimatter.

[[InWhichATropeIsDescribed Trope Part the First]]: Anyone on television who is a person of faith is a person who will believe in anything. Unicorns. [=UFOs=]. Psychics. Snake handling. Bigfoot. Yes, [[AllMythsAreTrue all of them at once]], even if they are contradictory. Thus: ''If UsefulNotes/{{Jesus}}, Then Aliens''. "Believers" are [[BeliefMakesYouStupid gullible idiots]] who will accept pretty much anything as not just possible, but probable, or even likely.

Trope Part the Second: A skeptic, rationalist, atheist, "scientist" or other critical-thinking type believes in nothing. Thus the contrapositive, ''If Not Aliens, Then Not Jesus''. Alien abductions are bunk, and so are psychics, and therefore God does not exist. A declaration by a scientist that they do not believe in one thing, such as ghosts, automatically means they think that anything supernatural, including the spiritual and the religious, is total nonsense and anyone who believes otherwise is an idiot.

The rhetorical term for [[LogicalFallacies this kind of thinking]] is a "FalseDichotomy": A person must be either a [[AgentMulder Believer]] or a [[AgentScully Skeptic]], but may not ever be both, nor fall somewhere between the extremes. Any belief on one side or the other will result in all beliefs on that side so this trope can exist with the title implication often running in reverse; "if ghosts, then Jesus" is common.

The existence of characters of this type is sometimes caused by a WriterOnBoard, but more often is the simple result of taking complex, complicated real people with diverse belief sets and trimming them down into stereotypes so they can be pitted against each other in a "Faith versus Science Showdown" which might be resolved by a [[GoldenMeanFallacy Golden Mean Aesop]]. This usually just comes off as an insult to everyone involved. It's false equivalence, and further ignores the fact that from a skeptical point of view, the existence of one supernatural thing provides no reason to believe in another unrelated supernatural thing, while simultaneously ignoring the fact that many religions frown heavily on their followers believing in events defined as "non-natural" by that religion's chosen godforce. It's also ironically wrong for a different reason; people without religious beliefs are ''more likely'', statistically, to believe aliens exist in the universe, also ironically because of statistics that indicated that the universe has near infinite chances of other intelligent lifeforms existing. So a closer-to-truthful trope, if taking this example to the extreme, name might be ''If Aliens, No Jesus'' or, perhaps more fittingly, ''If Jesus, No Aliens''. That is to say, beliefs of these sorts tend to cluster, with Scully types believing in Jesus, angels, miracles, faith healing, etc. while Mulder types believe in bigfoot, [=UFOs=], psychics, and acupuncture, and there's very little overlap.

Done with a small amount of finesse, this particular conflict can actually be entertaining: thus we have AgentMulder and AgentScully in their original forms, with the small but interesting subversion that the original Mulder would believe any fantastic explanation except a religious one, while the original Scully would be reluctant to believe any fantastic explanation unless it was religious in nature, in which case they would swap roles: she would become the Believer and he would become the Skeptic. So Scully and Mulder weren't a pairing of a believer and a skeptic, but of two different and mutually skeptical believers.

Related tropes include AllMythsAreTrue and ArbitrarySkepticism. If the WriterOnBoard is in the "Believers" camp, a StrawVulcan or HollywoodAtheist is likely to appear; if in the "Skeptic" camp, expect at least one, and probably more, examples of HolierThanThou and BeliefMakesYouStupid.

Not to be confused with NoSuchThingAsSpaceJesus, which is the opposite. Sort of.


[[folder:Anime and Manga]]
* In one episode taking place near Christmas in ''Manga/AzumangaDaioh'', Kagura, who isn't exceptionally bright herself, [[AluminumChristmasTrees asks if reindeer are actual animals]], correctly concluding that the nonexistence of Santa does not preclude the existence of reindeer sleds. Tomo starts to taunt everyone about thinking reindeer exist, falsely assuming that the nonexistence of flying sleds precludes the existence of any reindeer as well.

[[folder:Comic Books]]
* The graphic novel ''Comicbook/CreatureTech'' had anů interesting take on this. The protagonist, Dr. Ong, is an atheist and a brilliant scientist, working at [[ExtranormalInstitute a top-secret lab researching the weird and supernatural]]. Then, he runs across the actual ShroudOfTurin at work (they know it's the real deal because the blood on it heals people and raises the dead). This makes Ong admit to his preacher father that Jesus must have really been the Son of God, but he doesn't give anything more than intellectual assent to Jesus. Dr. Ong remains this way, until a teleportation accident lands him on another planet, at the foot of a cross where an Alien Jesus is being crucified. I kid you not: ''If Alien Jesus, then Jesus.'' ''Creature Tech'' is all over this trope. Ong's father was driven to religion by his findings as the previous scientist working at the aforementioned institution: [[InvertedTrope If aliens, then Jesus]]. He also objects to the Shroud of Turin because having conclusive evidence of Jesus' divinity would deprive people of the right to ''choose'' whether to believe in Christ.
* Franchise/{{Batman}} (depending on the writer) has been seen denying the existence of ghosts, magic, and gods other than the Comicbook/NewGods (whom he doesn't seem to consider gods). On the rare occasions when he ''does'' [[OutOfCharacterMoment admit to the existence of magic]], other characters [[LampshadeHanging usually notice.]]
** Here's an example from ''JLA''.
-->'''Atom:''' ''(As Batman consults Manitou Raven)'' This is bad... he's going to the dark side.
-->'''Firestorm:''' What, Batman has a light side?
-->'''Atom:''' I mean magic. He's really desperate.
* ''Doctor Thirteen'', ever since being integrated into the main DC universe, has usually been depicted as a FlatEarthAtheist without peer, all too willing to deny the supernatural no matter how conclusive the evidence. In the "Architects and Mortality" storyline, he teams up with a vampire, a ghost pirate, a talking gorilla, and a time traveler, among others. One of his earliest denials of the whole affair hinged upon the fact that the "yeti" he saw the other day was actually the vampire in a very heavy coat, and if yetis don't exist then neither do vampires, and he's having an extremely vivid dream or hallucination.

* ''Film/{{Contact}}'' started out avoiding this trope by having Creator/JodieFoster's character, Ellie Arroway, believe in aliens yet not Jesus, although the other characters tended to believe in either everything or nothing. After Ellie's trip through a stargate machine built from alien-transmitted instructions, however -- a trip which nobody believes actually happens ([[spoiler:after encountering an alien intelligence who appears as her dead father, she returns to Earth in the same instant she left with no recorded evidence of her trip at all, [[TheReveal other than that 18 hours of recorded static]]]]) -- she finds herself in a position she previously dismissed in other characters: furiously arguing for the truth of a cosmically important experience for which she can provide no hard evidence at all. While Ellie doesn't go so far as to literally believe "if Aliens, then Jesus", that message, [[AlternateAesopInterpretation whether intended or not,]] is not too much of a stretch.
* This is ultimately the crux of the judge's decision regarding the existence of Santa Claus in the climax of the remake of ''Film/MiracleOnThirtyFourthStreet'': If the U.S. government has the wherewithal to put "In God We Trust" on their money, then who is he to declare false the faith that Kris Kringle is Santa Claus?
* ''Film/FourteenOhEight'' had a super-rationalist reporter who debunks tales of hauntings as the protagonist. He checks into a hotel room which, of course, actually is haunted. The movie indicates that the reporter is also an atheist. At the end of the movie, having found himself unable to explain away the haunted hotel room, he comes to the conclusion that there must be more "out there" than what he can see and touch, and has his doubts about the nonexistence of God and an afterlife severely shaken. This is supposed to provide him some comfort over the death of his daughter. In other words: "If ghosts, then Jesus." The Creator/StephenKing short story on which this was based had a similar subtext: the line about not believing in "ghoulies and ghosties and long-leggity beasties, and even if they were real, there's no God to protect us from them, is there?" was lifted verbatim from the story for the movie. The story itself has the protagonist ending his days dealing with nightmares and half-recalled memories about the incident and contrasting the horror of mere "ghosts" with the terror of the room ("At least (ghosts) were human once, but that thing...that * thing* ...").
* At least two ''Batman'' films - in different continuities - have played this up, with Jesus swapped for You-Know-Who.
** In Creator/TimBurton's ''Film/{{Batman}}'' (1989), [[AgentMulder Alexander Knox]] is mocked by his fellow reporters for believing that there is a "Bat-Man." They joke that he must believe in Bigfoot too.
** Similarly, an early scene in ''Film/TheDarkKnight'' suggested that anyone who believes in Batman not only also believes in Bigfoot, but furthermore believes that Music/ElvisPresley and UsefulNotes/AbrahamLincoln are still alive.
* Lampshaded amusingly in ''Film/{{Ghostbusters 1984}}'', where embodying the first part of this trope is a hiring requirement for the Ghostbusters organization:
-->'''Janine:''' Do you believe in UFO's, astral projections, mental telepathy, ESP, clairvoyance, spirit photography, telekinetic movement, full trance mediums, the Loch Ness monster, and the theory of Atlantis?
-->'''Winston:''' [[OnlyInItForTheMoney Uh, if there's a steady paycheck in it, I'll believe anything you say.]]
** Played slightly more grimly not long thereafter, when Winston points out that the [[Literature/TheBible Biblical Book of Revelation]] might not be so far-fetched: "Ray, has it ever occurred to you that maybe the reason we've been so busy lately is 'cause the dead ''have'' been rising from the grave?" If Ghosts, Then Jesus plus End Of Days...
*** Actually subverted according to WordOfGod by Ray who was apparently once very religious according to Dan Akroyd but became a parapsycologist because of his lost faith (if not Jesus then Aliens if you will). It adds deeper meaning to both his statement he never met God (despite desperately wanting to) and his low-key freakout to Winston pointing out this may be God at work.
* In ''Film/SuperMarioBros'', Mario doesn't believe in parallel universes and aliens and stuff like Luigi does, and basically gets portrayed as a hard-nosed atheist for it. By the end of the movie, once he's gone through an adventure in a parallel universe, he's willing to believe anything.
* ''Film/{{Cthulhu}}''. The protagonist, having spent the night stumbling through [[AbsurdlySpaciousSewer endless tunnels]] beneath [[TownWithADarkSecret Rivermouth]] full of [[FishPeople nameless horrors]], ridicules his friend's suggestion that they're the legendary [[http://en.wikipedia.org/wiki/Shanghai_tunnels Shanghai tunnels]] (subterranean passages allegedly used to transport men kidnapped as slaves) and says sarcastically, "What other explanation could there be, [=UFOs=]?" Which is amusing given where the titular monster came from.
* Employed in ''Film/FromDuskTillDawn''. The existence of God is taken as proven by the existence of vampires. Possibly justified since all they needed was faith and if faith didn't work they were kinda screwed either way.
* Captain America in ''Film/TheAvengers2012''. While he refuses to believe Thor and Loki are gods ("There's only one God, ma'am, and I'm pretty sure he doesn't dress like that."), he accepts that they're magic-using aliens without question. Of course, he ''has'' seen the very-unscientific powers of the Tesseract [[Film/CaptainAmericaTheFirstAvenger first-hand]], so it's not that much of a stretch for him. Steve is technically correct, as well, given that in the movie universe, the Asgardians are supposed to be {{Sufficiently Advanced Alien}}s.
* Subverted for humorous effect in ''Film/TheLostSkeletonOfCadavra''.
-->'''Ranger Brad:''' Oh, say... You don't believe those old legends about the Lost Skeleton of Cadavra, do you?
-->'''Dr. Roger Fleming:''' Ranger Brad, I'm a scientist, I don't believe in anything.

* Apropos of Creator/GKChesterton, the ''Literature/FatherBrown'' stories subvert this trope pretty heavily - several stories feature the priest seeing through apparent miracles that take others in, precisely ''because'' he has a firm belief in the supernatural - and therefore a framework to think about them in, and an appreciation that "inexplicable" does not equal "miraculous".
* This trope is used to explain why Stanley Uris, one of the main characters in Creator/StephenKing's ''Literature/{{IT}}'' can't fully accept the existence of the book's creature and eventually [[spoiler: kills himself rather than return to face the monster]]. In one inner thought sequence he explains to the reader that [[spoiler: the existence of the monster actually OFFENDS him, because the existence of ANY supernatural phenomena destroys his neat and tidy rationalist vision of the world. "Everything leads to everything..."]]
* In Creator/LarryNiven's ''Literature/FallenAngels'', the "ruling coalition of proxmires, falwells, rifkins and maclaines" is composed of groups who in real life regard each other, sometimes literally, as minions of the Devil, but in the novel work harmoniously to make life miserable for the Good Guys, because nothing else counts against their (alleged) technophobic mindset. If Jesus, then crystals, and vice versa. If [[LuddWasRight Ludd]], then Jesus.
** This is stated to be the result of decades of political maneuvering; just as combining socialism with Catholicism to create liberation theology made the Catholic Church a supporter of the Soviet Union and extended the Cold War for a few more decades, combining Green and Catholic thinking into "Eco-fundamentalism" enabled the authorities to gain bipartisan support(Green liberals and fundie conservatives) and pretty much TakeOverTheWorld. A group marriage made in hell; Luddites, fundies, environmentalists and spiritualists all realizing they are NotSoDifferent in that they all yearn for YeGoodeOldeDays.
* Referenced in ''Literature/TheDresdenFiles''.
-->"Zombies. Jesus."
-->"I kinda doubt they had anything to do with that one."
* Inverted in Creator/CharlesStross' ''A Colder War'': an alternate-history USA is dealing with Lovecraftian horrors used as weapons by the Soviets. Ronald Reagan is elected and treats them as just another kind of technology - he's too religious to believe in any supernatural aspect to them. If Jesus, then not Cthulhu.
* In Creator/AnneRice's ''[[Literature/TheVampireChronicles Memnoch the Devil]]'', Lestat encounters a being that claims to be TheDevil, calling itself Memnoch, who takes the vampire on a journey, showing him Heaven and Hell, as well as the history of Earth from a Biblical (and Memnoch's own) point of view. When Lestat asks the obvious question (if extraterrestrial life exists), Memnoch answers that he doesn't know, as he never looked at any other world. So, vampires, God/Jesus, the Devil, angels, ghosts, spirits, witches... all exist. Aliens? Who knows? We got enough trouble here.
** It should be noted that Anne Rice wrote this novel (and all others about vampires and witches) before becoming a "born-again Christian" and renouncing her "heresy".
** The novel also explicitly mentions that besides setting the Universe into motion, God did not participate in human evolution, so there is nothing to indicate that this couldn't have happened elsewhere, especially since neither God nor his angels particularly care about any other planet.
** However, given the events of her most recent work, Prince Lestat and the Realms of Atlantis...yea extraterrestrial beings are definitely a possibility.
* Robert J. Sawyer plays with this trope extensively in ''Calculating God''. Thomas remains stubbornly atheist while several species of alien try to convince him that not only does God exist, but the math proves it.
* Creator/UmbertoEco's ''The Island of the Day Before'' has a 17th century Jesuit use the "If Jesus, No Aliens" argument, trying to convince the protagonist Roberto that other worlds do not exist. His argument is that, if there are other worlds with people on them, every single one would have to have a Jesus dying for that world's salvation, meaning the Crucifixion was not the unique, monumental event Christianity treats it as; on the other hand, if God were to create these worlds and ''not'' offer them salvation, he would not be the loving god Christianity treats him as. The Jesuit is not portrayed particularly sympathetically, and his line of doctrinaire "reasoning" contributes to Roberto's slow, steady [[GoMadFromTheRevelation descent into madness]].
** This was the reasoning used to condemn [[https://en.wikipedia.org/wiki/Giordano_Bruno Giordano Bruno's]] belief in the existence of other worlds as heresy, and him to the stake, in [[RealLife Real Life]].
* In Creator/AndreiBelyanin's ''The Thief of Baghdad'', the author relays a FishOutOfTemporalWater scenario, in which a modern-day Russian man is magically transported into ArabianNightsDays by a genie to become the legendary titular character. The story (and sequels) feature all manner of Middle Eastern magical creatures. The author decides he shouldn't stop there and invoke this trope. After all, if a guy can be abducted and sent into the magical past by a genie, then why can't he also be abducted by a flying saucer in the middle of a Baghdad street chase, causing the guards to run away in fear, claiming that St. Khidr's chariot has taken the thieving infidel for righteous punishment.

[[folder:Live-Action TV]]
* In ''Series/NUMB3RS'', this trope seems to crop up with distressing regularity. Every few episodes, Charlie is challenged to move beyond the empirical world to a matter of faith, only the matter of faith in question is something completely outside the normal debate of science vs. religion, and yet Larry's right there urging Charlie to consider that it might possibly be true. After all, even scientists don't pretend that they can know everything, right?
** Note that Charlie is about the only straight example of the trope in the show. His brother is as likely to believe or disbelieve things. Larry, a scientist, is far more open to belief in the supernatural than Charlie is.
* Played surprisingly straight in ''Series/ThirtyRock''. Religion plays a negligible role in most characters' lives, except when PlayedForLaughs, i.e. when Liz Lemon states that her religious beliefs are "pretty much whatever Oprah tells me to do." However, Kenneth, the one (non-GirlOfTheWeek) character who is devoutly religious, is also strongly hinted at as being [[TheAgeless immortal]].
* ''Series/JoanOfArcadia'': "Touch Move" as well as several other episodes.
* Both ''Series/BuffyTheVampireSlayer'' and ''Series/{{Angel}}'' avert this trope. They've seen vampires and demons of all kinds, but Buffy is agnostic, unknown what Angel is. Buffy wears a cross necklace, but only as a weapon against vampires.
-->'''Vampire Holden Webster''' ''(after discovering vampires and Slayers exist)'': Does God exist, by the way? Is there any word on that?
-->'''Buffy:''' [[ShrugOfGod Nothing solid.]]
** In the Buffyverse, ''everything'' of legends (vampires, werewolves, Bigfoot(feet?), Loch Ness Monster, etc.) are real. Except leprechauns.
** All of the above is probably a case of WriterOnBoard, since Creator/JossWhedon is a known agnostic.
* John Locke of ''Series/{{Lost}}'' fame is one of the few explicit representatives on TV of that (not insignificant) portion of society who are very spiritually inclined but not religious. This has led to him being used as a foil for another character's belief system multiple times: he contrasts with Jack, who is shown (at least early on) to be very earthly and skeptical; he also contrasts with Mr. Eko, whose spirituality is of a deeply religious nature.
* This trope was actually mentioned by a character in ''Series/{{Baywatch}}'' as her personal beliefs. In her own words, "If there can be aliens, there can be elves." The supernatural, however, was not a part of the show. Until the ''BaywatchNights'' spin-off.
* Averted by the characters of Dave Lister and Arnold Rimmer in ''Series/RedDwarf''. In true [[Creator/GKChesterton Chestertonian]] fashion, Rimmer scoffs at the notion of God but is frighteningly eager to declare any unexplained phenomena the work of aliens; Lister, on the other hand, is a pantheist but also considers human sapience to be alone in the universe (Lister is closer to correct; all the "alien" species they encounter evolved from Terran life forms). On the other hand, Lister is also described as or implied to be an atheist a couple of times as well - so either he became a pantheist at some point or it's just another case of Red Dwarf's rampant {{retcon}}ning.
** To be entirely precise, Rimmer effectively substitutes belief in {{sufficiently advanced alien}}s for a belief in God while Lister is more of an irreligious skeptic (either believing in no God or in the universe as a non-personal God). This doesn't really conform to this trope, either straight or as an aversion.
** Lister was stated to be a Pantheist in "Last Days", part of the third season, while he was stated to be an Atheist in "Back to Reality", the final episode of the fifth season. This means it's not implausible that Lister originally had faith in the idea of the universe being a non-personal god, then gave up believing in any form of god at all.
** Inversely, after the first two seasons, Rimmer's obsession with finding aliens is toned down to the point of vanishing completely, whereas despite mocking the idea of believing in God in the first season, in the third season episode "Timeslides" it's implied he's attended a church service onboard the ship (although who was conducting it is anyone's guess) and in "Last Day" he says people shouldn't be mocked for their beliefs (it's probably a side effect of suddenly [[CanonDiscontinuity coming from a different century]]).
* The short-lived sci-fi series ''Series/SpecialUnit2'' centered on a secret police bureau devoted to tracking down "Links", evolutionary deviations that were responsible for the ideas of classical monsters. Throughout most of the series, there's a scientific explanation for most of the deviations. The episode "The Eve", however, quickly set about suspension of disbelief to tiny little pieces. A Link so old and so powerful he's considered the Devil? Sure. He can raise people from the dead? Okay. There's a prophecy about him? Sure, you could buy precognition. He needs a magic ring to carry out his plans? Er, all right, you could buy that it's of special AppliedPhlebotinum. He needs to pull off a ''magical ritual'' to gain the power? Oh, fuck that noise.
* ''Series/TheXFiles'' is a subversion: Mulder, who appears to be an atheist or agnostic, believes in aliens and most paranormal reports. Scully, who struggles with her faith, but still is shown to be a believing Catholic, initially denied the existence of most paranormal phenomena.
** This subversion was most apparent in any episode featuring religious supernatural phenomena. Mulder and Scully would actually switch roles, with Mulder being the skeptic and Scully trying hard to believe.
*** The two agents' views on the paranormal are completely inverted very early on in the Season 1 episode 'Beyond the Sea'. Serial killer Luther Boggs (who Mulder helped apprehend) claims to have had psychic revelations regarding a kidnapping case, but Mulder is particularly skeptical whereas Scully comes to believe him after Boggs reveals certain details regarding her recently-deceased father that he could not know. What doesn't help is that Boggs gets certain things wrong, such as 'reading' information from a scrap of 'evidence' related to the case that actually came from one of Mulder's t-shirts.
--->'''Scully:''' How is it that you're able to go out on a limb whenever you see a light in the sky, but you're unwilling to accept the possibility of a miracle? Even when it's right in front of you?\\
'''Mulder:''' I wait for a miracle every day. But what I've seen here has only tested my patience, not my faith.
* Slight subversion on ''Series/StarTrekDeepSpaceNine'': Major Kira is one of the most overtly religious characters on all of ''Franchise/StarTrek'', but also very cynical, sometimes even about the aliens/gods her people worship. The gods of the Bajorans, known as "The Prophets", are referred to by most of the other characters on the show as simply "The Wormhole Aliens". Captain Sisko starts off as one of the latter, but his belief grows as the series progresses and he comes to accept his role as a type of religious leader for the Bajorans. Likewise, the race of changelings are seen as "gods" by those they rule over, but not by others. There is also this exchange between two of the show's antagonists:
-->'''Weyoun''': Pah-wraiths and Prophets. All this talk of gods strikes me as nothing more than superstitious nonsense.
-->'''Damar''': You believe that the Founders are gods, don't you?
-->'''Weyoun''': That's different.
-->'''Damar''': [laughs] In what way?
-->'''Weyoun''': The Founders ''are'' gods.
** In another conversation, Odo asks if Weyoun has considered that the Founders may have simply programmed belief in their divinity into the Jem'Hadar and Vorta.
-->'''Weyoun''': Of course they did-that's what gods ''do.''
* Crops up in an episode of the American version of ''Series/{{Life On Mars|2008}}''. The young cop, Chris, states that he ''wants'' to believe in aliens because then angels aren't so far of a stretch. Because if there are flying saucers out there, that means God exists, right? Inverted, in that he seems to believe If Aliens Then Jesus.
* Grace Van Pelt in ''Series/TheMentalist'' is like this. She is a religious believer and also believes that a relative is a psychic, and asks the titular mentalist how to distinguish "true" psychics from "false" ones. Patrick Jane dismisses her with a categorical "There is no such thing as psychics" but she refuses to acknowledge it. In this case the connection was sensible, since her belief in psychics specifically revolved over their supposed ability to communicate with the dead, the afterlife being central to Christian doctrine.
* ''Series/{{Eureka}}'', "God Is In the Details".
* In ''Series/{{V 2009}}'', the inverse happens where people start to become more religious when the aliens invade. When visiting the Vatican, Anna demands that a cardinal tell all Catholic priests to stop demonizing [=Vs=]. When the cardinal not only refuses on the grounds that he can't stop priests from expressing their opinions but he also supports their skepticism of the [=Vs=]' intentions, Anna then explains that, since Christianity is founded on the belief in miracles, V technology can be used to make more things that appear to be just as miraculous to an average human. Basically, she threatens him with Catholics choosing to abandon their faith in favor of the [=Vs=], and he caves in.
* ''Series/CriminalMinds'' inverts this. Rossi (Catholic) and Morgan (unspecified Christian denomination) are the two most skeptical members of the team when it comes to psychics in "Cold Comfort" and demonic possession in "Demonology," although Rossi acknowledges the power of belief in such things - very negatively in the case of psychics (who waste investigators' time). Morgan was also skeptical of near-death experiences in "Epilogue", doubting that such instances were really glimpses of the afterlife.
* ''Series/{{JAG}}'': Played with in "Psychic Warrior", in which a skeptical mathematician was asked by Rabb on the stand, in a case dealing with a Navy experiment on remote viewing, if he believed in God. He reluctantly admitted it. Rabb then criticized his lack of belief in the possibility of psychic phenomena.
* On ''Series/TheWalkingDead'', Daryl brings up the Chupacabra and T-Dog expresses disbelief. The reply is, essentially, "The dead are walking and you don't believe in the chupacabra?" Well, thing is, there's ample evidence (in the show) for the walking dead...

* In Creator/WilliamShakespeare's ''Theatre/TheTempest'', Alonso declares, after spirits prepare a banquet, that he will now believe in unicorns and phoenixes. It's possible he's meant to be sarcastic, though, since he calls the spirits a "living drollery". Sebastian agrees with the sentiment.

* Played with in ''VideoGame/TheLostCrown: A Ghosthunting Adventure'', where Nigel is frustrated by Lucy's (wrong, but reasonable from what she's seen) insistence that the spooky things in Saxton Museum aren't necessarily proof of ghosts, just ''something'' strange. Nigel's own credibility later reveals its limits when Hardacre implies that he believes myths of ''dragons'' had a factual basis, an idea which even Nigel poo-poos as silly.

[[folder: Webcomics]]
* ''Webcomic/SaturdayMorningBreakfastCereal'' presents [[http://www.smbc-comics.com/index.php?db=comics&id=1356 its take on this trope]].
-->[[GoodNewsBadNews Well, the good news is that we found out Jesus is worshipped on other planets]].

[[folder:Western Animation]]
* In ''WesternAnimation/TheSimpsons'', Lisa's careful balance between sweet little girl and intellectual genius was broken severely by the episode "[[Recap/TheSimpsonsS9E8LisaTheSkeptic Lisa the Skeptic]]" where they found an angel's fossilized remains. Lisa is portrayed as a condescending and atheistically unbelieving skeptic, despite the fact that she was always portrayed as being somewhat religious before then (and after, to the point where when she lost her religion she was not satisfied until she found another, namely Buddhism, though these are not necessarily incompatible positions-some forms of Buddhism reject the existence of gods, and even can be taken as purely philosophical, without supernatural beliefs). To her credit, we are talking about not believing in angel fossils here (an idea which doesn't make sense even if one ''does'' believe in angels, which are generally understood to be immortal beings of pure spirit). And she was right, they weren't angel fossils at all.
* Mocked in ''WesternAnimation/TheVentureBrothers'' episode "Ghosts of the Sargasso" when Hank Venture falls under the sway of Part One.
-->'''Hank:''' Brock, if pirates really exist, I mean, Santa Claus and the Tooth Fairy could even be real, right? It's like, all bets are off!\\
'''Brock:''' Hank, nobody ever said pirates don't exist.
* In ''WesternAnimation/BatmanBeyond'', Bruce displays a healthy attitude to this kind of trope, not dismissing anything out of hand (having encountered his share of paranormal phenomena during his own cape and cowl career) but not blankly accepting all supernatural claims either.
-->'''Bruce:''' These people believe that anything they can't explain is magic.\\
'''Terry:''' And naturally you don't believe in that kind of thing.\\
'''Bruce:''' Of course I do. I've {{seen it all}}: Demons, witchboys, immortals, zombies. But [trashing parts of a high school and attacking a bully], it's just so...so ''high school''.
* In ''WesternAnimation/InvaderZim'', when Dib proves that Chickenfoot is a hoax.
-->'''Reporter 1:''' I bet this means [[BigfootSasquatchAndYeti Bigfoot]] is a fraud too!\\
'''Reporter 2:''' And [[FlyingSaucer UFOs.]]\\
'''Reporter 1:''' And [[TheLastOfTheseIsNotLikeTheOthers hobos.]]\\
'''Dib:''' No wait! Those are real! [[Funny/InvaderZim Except the hobos. Wait, no]]. They're real. I... I guess. But- [[SurroundedByIdiots what's wrong with you people!?!]]
** Dib at one point ran into a guy who believed in aliens, and that vampires exist, but dinosaurs didn't.
* [[PlayingWithATrope Played with]] in ''WesternAnimation/AmericanDad'': The ChristmasSpecial episodes show that God, Jesus, and angels are all real. Aliens are real by virtue of Roger (an alien escaped from Area 51) living with the family. A two-part episode even deals with the Rapture, the Second Coming, and the war with TheLegionsOfHell. When Jesus meets Roger, he offhandedly mentions that Roger's people are one of his father's side projects, infuriating Roger. Meanwhile, Roger is busy fixing his ship to get the hell away from Earth before it becomes the literal Hell. Whether the Christmas episodes are "canon" (as much as that means) is debatable, though, and regular episodes rarely follow suit with the overtly Christian figures (though other supernatural creatures, like leprechauns, do appear from time to time).
* A bizarre example in ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy'', "Skeletons In The Water Closet": "Germs. They're real. Maybe skeletons are real too."
* ''WesternAnimation/MikeLuAndOg'': In "A Learning Experience", Mike asks who the Cuzzlewitz are, and Lu scoffs "Next, you'll be asking about the Easter Bunny." Of course, she ''does'' know they're real, [[IrrationalHatred but she really wishes she didn't]].

* The author Robin Ramsay actually puts forth the "If Jesus then Aliens" theory in his book [[http://www.amazon.com/Conspiracy-Theories-Pocket-Essential-Ramsay/dp/190404865X/ref=sr_1_19?ie=UTF8&s=books&qid=1201017913&sr=1-19 about conspiracy theories]].
* TruthInTelevision: There exists (at least) one cult that believes [[http://www.cnn.com/US/9803/19/saucer.cult/ God would come to Earth in a flying saucer]].
** [[Film/StarTrekVTheFinalFrontier What does God need with a starship?]]
*** Really that question could have infinite number of answers with regards to God/Gods, anything from [[RuleofCool Rule of Cool]] to [[GodinHumanForm God in Human Form]]
** Despite popular belief, [[ChristianityIsCatholic The Vatican]] has historically had an attitude of "God can do anything, so anything is possible." When Copernicus' friend Johann Albrecht Widmannstetter lectured about the early findings implying a heliocentric solar system, Pope Clement VII and several cardinals all attended, were fascinated, and one wrote a letter to Copernicus encouraging him to publish his findings. With the exception of a few {{Obstructive Bureaucrat}}s using scripture to push an agenda, the Catholic hierarchy has been silent or supportive about just about every scientific theory. True to the trope's name, they've even come out in support of the existence of alien life.
*** The Vatican even has a planned amendment to its doctrine if intelligent alien life is discovered.
*** Depending on one's interpretation, Jesus himself [[http://www.biblegateway.com/passage/?search=John%2010:14-16&version=KJV may have spoken about]] the existence of aliens.
** Galileo actually got in trouble not for the heliocentric solar system theory, but for accidentally insulting his friend, the Pope, who himself leaned towards heliocentrism, in a [[http://tofspot.blogspot.no/2013/10/the-great-ptolemaic-smackdown-table-of.html strange series of events]]. Court politics and Galileo's... [[JerkAss acerbic character]] did the rest.
** Reports of AlienAbduction are steadily increasing, while reports of being impregnated by horny gods or demons have all but vanished (supposed house hauntings and demonic possessions, however, remain popular).
** Most branches of UsefulNotes/{{Mormonism}} have believed in the existence of "worlds without number" and the life thereon almost from the beginning of the movement. The Earth merited a visit from Jesus because it is apparently [[CrapsackWorld the most wicked planet in God's domain]]--although it is also [[AWorldHalfFull the most righteous]].
** A fairly important and well-educated Orthodox Christian author Pheophan the Anchorite, while responding to an obviously heretical statement about Jesus actually being an alien (back in the [=1800s=]) said that the problem is that we simply don't know anything about aliens, such as whether or not they even exist, and if they do, did they commit the original sin or not, and if they did, was it necessary for Jesus to die again just for them, and if it was, etc, etc.
*** Which is the basic premise of CS Lewis's speculative fiction novels, Out of the Silent Planet and Perelandra, as well as the Narnia books.
** One of the founders of Seventh-day Adventism, Ellen G. White, invokes this trope literally by claiming God himself gave her [[http://www.whiteestate.org/books/egwhc/EGWHCc07.html visions regarding created beings on other planets]]. According to her, God created multitudes of worlds before Earth, where the inhabitants were still perfect and unfallen (unlike humanity after the whole Adam and Eve thing).
* There is an old joke about a UFO landing and an alien pops his head out the door the first thing he says is, "Has Jesus been through here yet?"
* Another old joke--an atheist is walking through the woods when Bigfoot jumps out and starts chasing him.
-->'''The Atheist:''' God save me!\\
'''God:''' I thought you didn't believe in me?\\
'''The Atheist:''' Yeah, well, until a second ago, I didn't believe in Bigfoot either.
* {{Subverted|Trope}} by [[http://www.nytimes.com/2010/11/13/us/13beliefs.html?_r=2&partner=rssnyt&emc=rss this article]], about a ufologist who ''wants'' religiously-minded scholars to open up to non-spiritual kinds of paranormal phenomena but is having trouble.
* Methodological naturalism kind of flip-flops on this point. The world view focuses on that which is observable, and where cause and effect are connected, i.e. an evidence-based system. Because the supernatural and other associated things are deemed inherently without evidence, methodological naturalism makes no judgment on them, leaving them out of scope. While the default position most seem to take is to not accept an idea without evidence, changes to our understanding of the natural world could lead to accepting a whole new range of things. In other words, once there is evidence for the supernatural, it ceases to ''be'' supernatural, and becomes "natural, if weird and yet unexplained." Some however disagree with this concept. If one found hard, reproducible evidence that meets scientific standards of something that violated gravity (such as levitation) that could be deemed supernatural (above or beyond the natural laws) and if, except for this phenomena, gravity still was seen to hold, it would not disprove these laws, or require their alteration. It would raise a ''lot'' of questions, naturally, but any new discovery will do the same. Methodological naturalism is more of a guideline-scientists assume, for the sake of simplicity, that nothing supernatural will interfere with the results of experiments, otherwise science couldn't be done. If there were such irrefutable evidence for the supernatural, that could be studied just as natural phenomena. Some religious organizations like the Catholic Church do investigate supernatural phenomena (miracles, demonic possession) scientifically, for instance.
* Humorously put in a Tim Minchin beat poem, "by definition, I begin, alternative medicine, I continue, has either not been proved to work or been proved not to work. Do you know what they call alternative medicine that's been proved to work? Medicine."
* People in the skeptical movement, for instance Wiki/RationalWiki, call this "[[http://rationalwiki.org/wiki/Crank_magnet crank magnetism]]," in which believers in unscientific or bizarre theories tend to quickly accumulate more. They suggest that a person who believes that science is wrong on one thing will often jump to the assumption that science is wrong on everything, that people tend to think of all scientists or authorities as being a united front against them, and that people who possess these beliefs tend to be easily-led by pseudoscience and woo. When you hear a creationist explain that all the fossils were fakes planted by [=UFOs=] from Atlantis, you're running into a full blown case of crank magnetism.
* A recent favorite of the Italian Website/YouTube community is Matteo Montesi, an ardent Christian believer who also, in his ''[[ArchivePanic hundreds]]'' of videos, talks about [[ConspiracyTheorist conspiracies]], aliens, ghosts, TheReptilians, and many other pseudo-scientific theories, and seems to believe in them all equally. For example, [[http://www.youtube.com/watch?v=bqsgOpuzE-4 here]] he talks (Italian only) about the supposed [[http://en.wikipedia.org/wiki/Nibiru_collision Nibiru Collision of 2012]], getting angered when faced with the possibility that nobody believes what he's saying.
** Also, he seems to believe that Jesus is both a deity and an [[AncientAstronauts Ancient Astronaut]], and so are the TheReptilians, described as "clones of the Fallen Angels" devoid of any memory of their divine status. Thus, he may be on the polar opposite of the Raelien cult (see 'below): while the Raeliens are atheists granting aliens what is the equivalent of divine status, Montesi is a believer granting deities physical and humanoid-like interactions with our continuum. To put it mildly: "Aliens are Jesus, Jesus is every good unnamed alien in history".
* The Raelien cult subvert this in a very weird fashion: they believe that "gods" were AncientAstronauts (a la Stargate); at the same time, however, these aliens did very God-like things, such as creating human life on earth from their DNA. So while they are technically atheists, and contend their views have a scientific basis (even alleging they have performed the first human cloning) it's very ''different'', to put it mildly. If Aliens, Then Not Jesus.
* Christians who take the Bible in its most literal form usually do ''not'' believe in aliens due to the fact that Jesus came to Earth in human form and died in that form, and has forever taken on physical human form after rising from the dead. Why would He take on the form of a human, permanently, if there are other forms of life in the universe that don't look human? Why would he come to just one planet if others had life? Did literally none of those planets have a fall from grace? Also, as God proclaimed man to be made in His image, this precludes the idea of intelligent forms of life that look different from "the image of God". In this case, it is If Jesus, then [[AvertedTrope Not Aliens]]. Or at least, HumanAliens only.
* Last but not least, Young Earth Creationists (Christians who take the book of Genesis in its most literal form) typically disbelieve in aliens -- since Earth is given special attention in the creation story. However, it should be noted that nowhere in Genesis is other planets mentioned -- and the sun is treated as a separate entity from other stars.
* Many ''Franchise/IndianaJones'' fans averted this, being fully accepting of divine power in the [[Film/RaidersOfTheLostArk first]] [[Film/IndianaJonesAndTheTempleOfDoom three]] [[Film/IndianaJonesAndTheLastCrusade movies]] but considering the aliens in [[Film/IndianaJonesAndTheKingdomOfTheCrystalSkull the fourth movie]] to be out of place.
