Conspiracy theories have been captivating Americans for centuries and with the birth of social media these theories have spread even further and faster than ever before. It is time to unravel the truth behind nine of the most popular American conspiracy theories. From the moon landing to Area 51, let´s dive deep into captivating stories that spark debate.

Introduction – Conspiracy Theories

In this article Fast Fact Fiesta dives deep into nine of the most captivating American conspiracy theories in this comprehensive analysis.

From the controversial “Did we really land on the Moon?” to the enigmatic Area 51, the aim of this article is to explain what each conspiracy theory is all about and take a meticulous look at the evidence, arguments, and counterarguments that fuel these theories. Our objective is not to confirm or debunk these theories, but rather, to present a balanced view that lets you evaluate the available information critically.

Remember, the aim is to encourage thoughtful discussion and discernment, not to propagate unverified claims.

Let´s dive into the intriguing, perplexing, and sometimes baffling world of popular American conspiracy theories.

1. The Moon Landing Was Faked

5 percent strongly believe that the moon landing was faked
In a 2019 survey on conspiracy theories in the United States, by Statista, the respondents were asked whether they think the moon landing in 1969 was faked, or not. Five percent of respondents stated they strongly believe that the moon landing was faked, while 61 percent said they strongly disbelieve.

The theory

The Moon Landing is one of the most discussed and biggest conspiracy theories out there. It was an incredible achievement for humankind, yet many people believe we never went to the Moon at all and instead all was faked.

Arguments supporting the theory

Theories surrounding this iconic moment range from claims of tampering and fabrication to allegations of outright fakery.

Proponents of these ideas cite various evidence such as inconsistencies in photos from the Apollo 11 mission, missing shadows on the lunar surface, and the “lack” of stars visible in footage taken during the landing.

Some have cited the fact that the American flag appears to be blowing in the wind, which is impossible on the moon due to the lack of atmosphere.

Others have even gone so far as to suggest that Stanley Kubrick staged the entire thing with help from NASA.

Arguments against the theory

Despite its popularity, there is no real evidence backing up any of these theories. In fact, countless scientific studies over the last five decades have confirmed beyond reasonable doubt that Neil Armstrong did indeed take “one small step for man” onto the moon’s surface back in 1969 – setting off an unprecedented era of human space exploration that continues to this day.


In conclusion, the theory that Neil Armstrong and Buzz Aldrin never landed on the Moon and that the landing was all faked, is one of the most popular conspiracy theories out there. While there is some evidence that suggests it may have been faked, there has yet to be any proof backing up these claims. On the other hand, a number of scientific studies have confirmed that the Apollo 11 mission was in fact successful and that Neil Armstrong did indeed take ‘one small step for man’ onto the lunar surface. Therefore, the Moon Landing was indeed real.

2. There Is A Deep State In The United States

16 percent believe in the deep state theory
In the 2019 survey respondents were asked whether they believe in the conspiracy theory of a secret and powerful "deep state" working against President Trump and his supporters, or not. 16 percent of respondents stated they Strongly believe in this deep state theory, while 33 percent said they strongly disbelieve.

The Theory

The idea of a ‘Deep State’ in the United States has been gaining traction for quite some time, particularly among those who believe their government is not transparent and accountable. It’s an idea that suggests there are powerful political figures and entities with hidden agendas, operating behind the scenes to control or influence governmental decisions.

Arguments supporting the theory

Supporters of this theory point to events such as the revelations from whistleblowers Edward Snowden and Chelsea Manning, which demonstrate how little we really know about what goes on inside our government.

Proponents suggest that these clandestine forces seek to undermine democracy by manipulating public opinion and influencing policy without being held accountable for it. They argue that these conspiracies go back decades, citing instances like Watergate and Iran-Contra as evidence of deep state interference in US politics over the years. Additionally, they contend that powerful interests have used the ‘deep state’ to further personal ambitions; while critics see this view as paranoid conspiracy-mongering.

Arguments against the theory

There is no evidence of a coordinated, intentional effort to subvert U.S. government policies by a group of individuals.

The concept of a “Deep State” has been used historically to describe the military, intelligence, and other government agencies, which operate independently of the elected government. In the United States, however, these organizations are held accountable to elected officials and are subject to oversight by Congress.

The American system of checks and balances is designed to provide oversight and accountability of all branches of government and to prevent any single branch from controlling the government.


Despite disagreement over its existence, many people still believe in one form or another that something suspicious is going on within our government – whether it be shadowy officials acting outside of public scrutiny or influential corporations wielding undue power. This debate highlights both sides’ distrust of authority but also serves to highlight just how important open dialogue between citizens and their elected representatives truly is.

3. September 11 Was An Inside Job

Respondents were asked whether they believe in the conspiracy theory that the attacks on the World Trade Center on September 11, 2001, were an inside job, or not. 11 percent of respondents stated they strongly believe in this theory, while 45 percent said they strongly disbelieve.
Source: Statista

The Theory

The September 11 terrorist attacks on the twin towers are still a source of contention and suspicion for many. The idea that the attack was an inside job suggests that those in power had prior knowledge, or even worse, were complicit in the tragedy. This conspiracy theory is among the most widely considered among the American public.

Arguments supporting the theory

Proponents argue that there were too many inconsistencies within official reports surrounding 9/11 to be overlooked. They point to evidence ranging from multiple air defense failures by NORAD on the day itself to questions over why certain buildings collapsed despite not being directly hit by planes as proof of their claims. Many believe this points to some kind of cover-up at best or outright involvement at worst.

Alex Jones, the far-right conspiracy theorist and founder of Infowars, is one of the most influential proponents of 9/11 conspiracy theories and has helped spread them widely.

Arguments against the theory

Those who disagree with these theories cite a lack of concrete evidence and point out how quickly they arose after the event took place as reasons why it can’t possibly be true. Opponents also consider that if something like what proponents suggest actually occurred, then it would have taken much longer than it did for them to uncover any shred of truth regarding their allegations.


In conclusion, the 9/11 attacks were a tragedy that shook the world. Subsequent investigations have confirmed that Al Qaeda was responsible for the attacks. Nevertheless, there are many who continue to believe that 9/11 was an inside job, or that the US government had prior knowledge of the attack and allowed it to happen. This theory has not been proven and is largely speculative. It is important to recognize that the attack was a tragedy and to focus on preventing similar attacks in the future.

4. Oswald Had Help In The Kennedy Assassination

During the survey, the respondents were asked whether they believe in the conspiracy theory that Lee Harvey Oswald didn't act alone in assassinating John F. Kennedy, or not. 24 percent of respondents stated they strongly believe in this theory, while 12 percent said they strongly disbelieve.
Source: Statista

The theory

The assassination of former President John F. Kennedy in 1963 was a shock to the nation and left people searching for answers. One of the most popular American conspiracy theories is that Lee Harvey Oswald had help when he killed JFK.

Oswald has been labeled as the lone gunman, but there are many skeptics who believe otherwise.

Arguments supporting the theory

For example, some argue that due to the number of shots fired within such a short time frame, it would have been impossible for one person to shoot multiple times from different angles without any assistance.

Additionally, there are those who claim that the evidence presented by the government does not support their theory that Oswald acted alone.

Supporters of this conspiratorial view, point out inconsistencies with official reports regarding things like bullet trajectories, eyewitness accounts, and other details surrounding the events leading up to and following Kennedy’s death which suggest foul play may be involved.

Arguments against the theory

There is no direct evidence to suggest that Oswald had any help in the assassination of JFK. No accomplices have ever been identified, and no hard proof has been uncovered that links anyone else to the crime.

It has been argued that Oswald had the skill and capability to carry out the assassination without any help. He was a former Marine and an experienced marksman.

The Warren Commission concluded that Oswald was the lone assassin and that there was no evidence that he had any help. This conclusion has been challenged by various people and groups, but it is still widely accepted. Link to the Warren Report


In 2022 the White House released thousands of documents on the murder of US President John F Kennedy in full for the first time. The released documents do not clearly state that Oswald had any help in the murder of JFK.
It’s unlikely we will ever know who else may have been responsible, or if anyone else was even involved at all – leaving us only with speculation about what really happened on November 22nd, 1963.

5. Roswell Theory – The Government Is Hiding Aliens In Area 51

The respondents were asked whether they believe in the conspiracy theory that the government is hiding aliens in Area 51, or not. Nine percent of respondents stated they strongly believe in this theory, while 34 percent said they strongly disbelieve.
Source: Statista

The Theory

According to a recent survey, 81% of Americans believe there is something being hidden in the mysterious Nevada military base known as Area 51. This has sparked wild speculation that aliens and their advanced technology may be kept top secret by US government officials.

The idea of an extraterrestrial presence at Area 51 first surfaced during the Cold War when rumors began circulating about unusual aircraft sightings (flying saucer) in the area. Since then, tales have spread like wildfire across the internet with many alleging a large underground complex exists beneath the base where unidentified flying objects are stored and studied.

What’s more, numerous whistleblowers have come forward over the years claiming to have seen evidence of alien life inside Area 51. Although none of these reports can be verified and no official statement from the US government has been made, this hasn’t stopped people from believing it could all be true.

6. Illuminati Secretly Control The World

9 Popular Conspiracy Theories in the United States

The Theory

When it comes to conspiracy theories, the idea that an elite secret society called the Illuminati controls the world is one of the most popular. But how much truth is there to this theory? Is it simply an unfounded notion or could there actually be something to it?

Let’s take a closer look at what we know about the Illuminati and their supposed power:

  • The Illuminati was originally founded in Bavaria back in 1776 by Adam Weishaupt as an Enlightenment-era secret society opposed to superstition and religious influence over public life.
  • Since then, its members have included some of history’s most influential figures such as Mozart, Voltaire, Benjamin Franklin and even George Washington.
  • Conspiracy theorists believe that these powerful people have secretly been controlling global events from behind the scenes for centuries, with many believing they are still active today.
  • Supporters of this theory also point out that certain symbols like the pyramid on US currency may indicate hidden ties between government entities and the Illuminati.

While there is no concrete evidence to support these claims, their popularity does suggest that some people find them intriguing enough to consider them credible. Whether you choose to believe it or not, one thing cannot be denied – the concept of a secret society calling all the shots as a world government has captivated imaginations throughout history and continues to do so until this day.

7. Search Engines Discriminate Against Conservatives In The U.S.

16 percent think search engines discriminate against Conservatives in the U.S.
Respondents were asked whether they believe in the conspiracy theory that search engines like Google are discriminatory towards conservatives, or not. 16 percent of respondents stated they strongly believe in this theory, while 31 percent said they strongly disbelieve.
Source: Statista

The Theory

The web can be a dark and twisted place, like an eerie house of mirrors. It reflects the shadows that lurk beneath our everyday lives – the deep-rooted conspiracy theories that keep us up at night. One such theory is the belief that search engines discriminate against conservatives in the U.S., ultimately influencing public opinion and creating an unequal playing field.

This idea has gained traction in recent years as more and more evidence mounts to support it. For example, right-wing websites are often buried on SERPs behind mainstream media links or even completely omitted altogether. On top of this, many conservative sites have alleged unfair treatment by Google when it comes to ad placement and other targeted marketing strategies.

In response to these claims, Google denies any wrongdoing but refuses to provide proof otherwise; its secrecy creates further suspicion among those who already believe they’re being censored. While it’s impossible to know for sure what’s going on behind closed doors, one thing remains clear: The stakes are high for anyone with a stake in the political game – especially given how powerful search engine algorithms truly are.

TIP: Stay informed about potential bias from search engines by reading both traditional news outlets and alternative sources every day so you don’t miss out on important information due to censorship or manipulation.

8. CIA Population Control – CIA Created HIV To Kill Homosexual And Black People In the U.S.

Respondents were asked whether they believe in the conspiracy theory that the CIA created HIV to reduce homosexual and African American populations, or not. Five percent of respondents stated they strongly believe in this theory, while 53 percent said they strongly disbelieve.
Source: Statista

The Theory

This conspiracy theory is an old one with a long history. It dates back to the 1980s, when AIDS first appeared in the United States. The idea behind it was that the CIA had deliberately released HIV into certain segments of society as part of a larger plot against homosexuals and black people.

The evidence for this claim is largely circumstantial; there’s no direct proof that the CIA created HIV or even knew about its existence before it spread among Americans. However, some argue that the government could have been aware of its potential dangers but chose not to act on them until they were too late. This lack of action has been interpreted by some as intentional negligence and thus further fuel for the fire of this particular conspiracy theory.

Despite being frequently mentioned over the years, there is still no concrete evidence backing up this notion and it remains just speculation at best. Even if we assume that such an insidious plan did exist, proving beyond doubt who was responsible and how exactly it was carried out would be near impossible at this point in time.

9. Climate Change Is A Hoax

During the survey, the respondents were asked whether they believe in the conspiracy theory that climate change is a hoax, or not. 13 percent of respondents stated they strongly believe in this theory, while 47 percent said they strongly disbelieve.
Source: Statista

The Theory

Climate change is a popular conspiracy theory that suggests global warming is not real, but instead created by people in order to control the population and gain power. Supporters of this idea see climate science as an agenda pushed by politicians, big business, and other powerful figures who want to line their pockets while controlling citizens through fearmongering.

Why do some believe that global warming is fake?

Proponents of this conspiracy claim that scientists’ research into climate change has been manipulated or falsified for monetary gain, with evidence being distorted to support the notion that humans are responsible for rising temperatures around the world.

They argue there’s no way to prove definitively whether man-made emissions have caused a rise in temperature because it’s impossible to measure what would’ve happened if certain actions weren’t taken. This leads them to believe global warming is nothing more than propaganda used by those in charge to scare people into believing something that isn’t actually true.

The proponents of this theory cite natural fluctuations in temperature over time due to solar cycles as proof that global warming isn’t real; however, many experts disagree and point out how carbon dioxide levels have risen consistently since the Industrial Revolution began. The overwhelming majority of scientific communities agree that human activity has had a significant effect on climate change — meaning this particular conspiracy is one we should view skeptically at best.

What facts are there to support the theory of climate change is a hoax?

There are no facts to support the theory that climate change is a hoax. In fact, the scientific evidence overwhelmingly supports the reality of climate change. Numerous studies conducted by scientists from around the world have found that climate change is happening and is mainly caused by human activities, such as burning fossil fuels and deforestation.

This is supported by the United Nations Intergovernmental Panel on Climate Change (IPCC), which states that it is “extremely likely” that human activities have been the dominant cause of the observed warming since the mid-20th century.

Additionally, the world’s leading scientific organizations all agree that climate change is happening and is caused by human activities. Examples include the American Association for the Advancement of Science, the World Meteorological Organization, and the American Geophysical Union.

As you may know or at least have guessed there are more than nine conspiracy theories in US. Here´s a short overview of six more:

The Chemtrail Conspiracy

This conspiracy theory suggests that the contrails left by aircraft are actually chemicals or biological agents deliberately sprayed for sinister purposes, such as population control or weather control.

Reptilian Overlords

There are people claiming that a secret race of reptilian aliens are the hidden rulers of the world and are manipulating world events from behind the scenes.

Flat Earth Theory

The Flat-Earthers claim that the Earth is actually flat and not round, and that those who believe it is round are part of a global conspiracy to keep the truth hidden.

The Mandela Effect

According to this theory, certain events in history have been changed or erased from the collective memory, suggesting that reality may be shifting or being manipulated in some way.

Vaccine Conspiracy

This Vaccine Conspiracy suggests that the pharmaceutical industry is deliberately creating and promoting vaccines in order to make money, despite their potential dangers to human health.

HAARP Conspiracy

A theory claiming that the High Frequency Active Auroral Research Program (HAARP) is actually a weapon designed to manipulate or control the weather or even cause earthquakes.

Alex Jones – One of America’s Most Influential Conspiracy Theorists

Alex Jones is one of America’s most influential and controversial conspiracy theorists. He is the host of the popular news and opinion show, The Alex Jones Show, and is the founder of the website His show and website have become a major platform for the dissemination of conspiratorial and far-right views.

Alex Jones has been involved in a number of high-profile controversies, including the promotion of false conspiracy theories about the Sandy Hook Elementary School mass shooting and the Boston Marathon bombing. He has also been accused of anti-semitism and racism. Despite this, he has been successful in gaining a large and loyal following. His show and website draw millions of views each month, and his views have influenced public discourse on a variety of topics, particularly in regard to the politics of the United States.

Why Do People Believe In Conspiracy Theories?

Many people believe in conspiracy theories because of a deep-seated mistrust of authority and the feeling that powerful forces are manipulating events behind the scenes. Conspiracy theories often fill a void of knowledge and provide an explanation for why things happen in the world. They also provide a sense of control for individuals who feel powerless against the larger forces of society.

Conspiracy theories also provide a sense of community for those who share similar beliefs. This sense of solidarity can be beneficial for individuals who feel isolated and alone in their beliefs.

Also, conspiracy theories can give people a sense of purpose and direction in life, as they may feel that they are part of a collective effort to expose the truth.

Conspiracy theorizing can provide an escape from the mundane reality of everyday life, providing an exciting narrative that can be more satisfying than the truth.


In conclusion, conspiracy theories have been a part of American culture for many years. While some may argue that they’re nothing more than unfounded speculation and paranoia, others point to compelling evidence that suggests there may be something behind these stories after all.

It’s estimated that 25% of Americans believe in at least one conspiracy theory. With the rise of social media and the internet, it’s easier than ever for people to access information about conspiracies, which could account for why this number is so high. From who killed JFK to whether or not we really landed on the moon, there are countless questions yet to be answered.

No matter what you choose to believe, it’s clear that conspiracy theories will remain an integral part of our society for years to come. We’ll continue debating their legitimacy while trying to uncover new facts – because as with any good mystery, sometimes it’s just fun to speculate.
