Irish people have ranked the 'fake moon landing' as their most popular conspiracy theory for 2020, a study has revealed.
Conspiracy fans in the Republic on average search for the theory on Google almost 400 times a month.
The debunked conspiracy, which set out that all or some of the elements of the momentous 1969 Apollo moon landing was faked by Nasa, is also the most popular internet search in India, Norway, Malaysia and other nations this year.
Crop circles, the supposed pattern created by alien spacecrafts in corn fields, is the top search in the UK with 9,900 searches per month.
The moon landing theory takes the number two UK spot (4,400 searches) followed by 'Lizard people', according to website Fresh Student Living.
The term is associated with the Reptilian conspiracy theory, which was popularised by former broadcaster and footballer David Icke, who is now a prominent conspiracy theorist.
He has repeatedly made unsubstantiated claims shape-shifting reptilian aliens control earth by taking on human form and gaining political power to manipulate human societies.
Other popular UK searches include the Loch Ness monster - the mythical large, long-necked prehistoric figure of Scottish folklore - along with the more modern conspiracy theory in relation to Canadian singer, Avril Lavigne.
In 2017, unfounded rumours emerged which posited that the songstress had been replaced by a lookalike.
Lavigne later dubbed the outlandish conspiracy as "dumb" and "weird".
Perhaps one of the lesser known conspiracies relates to Denver International Airport (DIA) in the United States. The landmark is a hotbed for conspiracy fans, with theories most commonly claiming that DIA is a secure headquarters used by the Illuminati or New World Order, Neo-Nazis, or Reptoids.
Also popular stateside is the theory that Beyonce is a member of the Illuminati, a supposed secret society plotting to create a New World Order through a one-world government.
The study points out that one of the main reasons why conspiracy theories are so appealing is that they offer explanations for seemingly random and inexplicable events, helping us feel more in control.
Confirmation bias also plays a big part, the study explains, and urges fans to carry out research which both supports and refutes the theory.
