A conspiracy theory is not really a theory at all, but is a term usually associated with an alternate account of history or an event that usually involves a person or group of people (conspirators) secretly plotting the outcome of events and then successfully passing said event off as a natural occurrence that involved no secret plotting. Many conspiracy theories do hold some water, while others are absolutely insane. Here are five of the craziest conspiracy theories.
5. Lunar Moon Landing Conspiracy

The Conspiracy:
The claim is fairly simple. NASA conspired with the US Government to fake the moon landings. Proponents of this theory say that the NASSA moon landings were filmed in a Hollywood studio. One organization has even went as far to claim that NASA hired famed director Stanley Kubrick to direct the moon landings and Arthur C. Clark wrote the script. They say the motivation for faking this trip was to win the space race against the Soviet Union (who curiously enough pop up again on this list a bit later). Conspiracy theory proponents claim that NASA would not risk sending men into space because if the mission went badly and the astronauts died it would embarrass the nation so they chose to fake the landing instead.
The Evidence:
You cannot make a footprint on the moon

There is no wind on the moon

The flag is blowing in nonexistent wind
The Shadows are created from multiple light sources

The Crazy:
Speaking hypothetically, let’s say that the first few moon-landings were faked. It is pretty much undeniable that NASA eventually did put a man on the moon with the Apollo 14 and 15 missions, so what does it really matter? Back in the real world, the flag appears to be blowing because it was made to look like it was blowing so when the astronauts placed it on the moon we could see that it was the U.S. flag and not the flag of some other country. On not being able to make a footprint on the moon, all I have to say is: What? Lastly, there have been countless experiments that have proven that you can get the shadows that were exhibited on the moon from one light source. Most famous of these were performed by the crew on the television show Mythbusters.
All the evidence that I need that Apollo 11 landed on the moon comes from Buzz Aldrin. When asked by a radio interviewer if the moon landing was faked, Aldrin replied by punching the radio host in the face.
4. Paul McCartney Is Dead!

The Conspiracy:
Paul McCartney, member of the legendary rock band The Beatles is actually dead. This conspiracy states that the real McCartney died in 1969 and in order to spare the public the grief of this great loss he was replaced by the winner of a Paul McCartney look-a-like contest named William Campbell. Strangely Campbell also had the same set of pipes as McCartney.
The Evidence:
This album cover:

Lennon is shown dressed all in white like a clergyman; Ringo Starr is in a black suit and represents the undertaker (The profession not the professional wrestler); George Harrison is in casual wear like a gravedigger (The profession not the monster truck); and McCartney is dressed like a zombie…I guess
Proponents also claim that playing Beatles’ songs backwards offers clues. Also, cryptic song lyrics suggest that Paul is dead. Like when Lennon sings “I Buried Paul” on the classic track “Strawberry Fields Forever”, but I’m pretty sure songlyrics.com says Lennon is saying “Cranberry Sauce”.
The Crazy:
Pretty much everything about this is absolutely crazy. All the evidence for this conspiracy theory is based on interpretation of lyrics, album covers, and Rorschach audio. I can interpret Beatle’s song lyrics a thousand different ways. For example, I do not think Lennon or Harrison is dead. I also know where Ringo Star is, and I do not believe that McCartney lives on terrestrial land. They all in fact live in a yellow submarine…A yellow submarine…A yellow submarine.
3. McCarthyism

The Conspiracy:
During the Cold War U.S. Senator Joseph McCarthy managed to whip many in the American population into a frenzy by claiming that America was being infiltrated by communists who’s mission was to destroy democracy and instill a communist society in America. McCarthy accused everyone from common people to constituents in the Senate to Hollywood actors, directors and screenwriters of being communists and pushing the communist agenda in America.

And, as seen by this photograph, if communists infiltrate America they will abuse minorities and women. Strangely, America did a pretty good job of doing that without communism all throughout the 1960s.
The Evidence:
If you disagreed with McCarthy in any way you were a dirty commie.
The Crazy:
The craziest thing about this conspiracy is that people bought into it and many legitimately believed that there was a sect of Americans that were trying to topple democracy and put communism in its place. For one, even if there were some “communists” in the U.S. Senate or House I don’t see anything wrong with that. It takes all kinds of people to make Democracy work, that’s why we have a representative form of government so all people in America are represented, and if there is a communist populace in the U.S. and they vote, they too can be represented, that’s how democracy works.
For example, did you know that the U.S. has a socialist senator:

-Bernie Sanders
Or an Atheist representative in the House:

-Pete Stark
It takes all kinds of points of view for Democracy to work properly and we are lucky that McCarthyism died out thanks to great journalists like Edward R. Murrow and others who helped put an end to the conspiracy accusations and exposed McCarthy for what he truly was, a crazy person. None-the-less McCarthy managed to monger fear in a large sect of the U.S. population that has yet to be rivaled.

-It’s getting there, though.
2. The New World Order

-No, not those guys!
The Conspiracy:
A secret but powerful organization with financial and political clout has been striving for over a century to unite the world under one totalitarian style of government that they will be in charge of. This theory is a favorite among militant Anarchists and some fundamentalist Christians who believe that this organization represents the apocalyptic coming of the Antichrist. It has been speculated among conspiracy theorists that this group that is secretly controlling everything could be the Freemasons, the Illuminati, or the Jews.
The Evidence:

The Crazy:
First of all, anything that tires to simply blame “the Jews” for anything is about as crazy as Mel Gibson and trust me when I say that he is pretty freaking crazy.

This is just good ol’ fashion paranoia at its best. The people who prescribe to this conspiracy theory are paranoid of government, paranoid of growing technology, and most likely paranoid of hygiene.
1. Reptilians

The Conspiracy:
These humanoid reptiles from the Alpha Draconis star system all ready inhabit Earth and have weaseled their way into prominent political roles. You see these lizard-people transform into a human form by drinking human blood. It has been speculated that the majority of the world’s leaders and decision makers are actually Reptilians.
The Evidence:
This Video:
V is actually a documentary film, probably directed by Michael Moore.

Iggy Pop:

The Crazy:
Reptiles disguised as people who turn into people by consuming human blood… That is the crazy.

U.S. Senator Joseph McCarthy was right.
0bama.
And Jews hate everyone whos not a Jew, it's nothing new or different than any other religion.
They just seem to get away with it.
you must be an avid fox news watcher.
Every single Jew HATES every single non-Jew, and they get away with it. Very bold statement which I have no doubt that you can back up. It should be noted that throughout history, the Jews have been expelled from 79 countries, and lets not forget the Holocaust.You sir a genius.
Sadly – McCarthy was right – read documents on the Venona Project – and read The Haunted Wood, by Allen Weinstein – he was a Russian Jew who defected from the Russian espionage and conspiracy to leak secrets and corrupt American officials/government on orders from Stalin.
It wasn't a crazy conspiracy – McCarthy was right. And FDR and Truman both laughed it off. What does that tell you.
The real crazies are those crazy enough to believe that any of the moon landings actually occurred. Even with the technology we have today, it still can't be done. Perhaps someday, in the future, who knows?
Wait…I see it now! The Illuminati is the organization of lizard people that controls the world! They faked the moon landings, replaced Paul, and started the Red Scare!
It’s all so obvious with the help of certain substances.
Everybody knows about McCarthy theory.
the moon landing was merely a hoax. people have proved that you can make a footprint of the moon it stays there because there is no wind.
reptillians are wishful thinking that aliens excist.
the presidents are masons. proven fact.
