A group of self-proclaimed paranormal researchers claim they have found proof of aliens near the city of Nazca in Peru.
The team say they have found a mysterious three-fingered ‘mummified humanoid’ with an elongated skull.
But not everyone is convinced of the finding, and one UFO expert says that this is simply a plastercast model.
In a short documentary on the bizarre find, Dr Konstantin Korotkov, a professor at Saint-Petersburg University, says that these features are not a deformity, but that the individual is ‘another creature, another humanoid.’
The body was found covered in white powder, which the team say was used to preserve the remains.
They claim that carbon dating samples of the body dates between 245 – 410 AD, though the validity of these tests has not yet been verified.
Writing for conspiracy theory website Ancient-origins, anthropologist Alicia McDermot said: ‘Open-minded scientists studying human origins may find themselves in a situation where they have to identify this surprising discovery as true, probable, or a false find.
‘It is important in these situations to remain curious yet skeptical.
‘We should keep an open mind yet stay apprehensive about jumping to conclusions on new discoveries, even if they seem incredible at first.’
Despite the excitement among conspiracy theorists around the new find, there may be a more simple explanation.
Leading UFO expert Nigel Watson, author of Haynes UFO Investigations Manual, told MailOnline: ‘I’m no expert on ancient mummified bodies but they tend to be more leatherish looking.
‘This seems to be a plastercast over a bone structure with three fingers attached to the hands.’
‘Such hoaxes are the product of wishful thinking mixed with greed and a lust for publicity.
‘The more exotic the claim the more viewers they generate, and so we get ever more bizarre ‘revelations’ about alien corpses, flying saucer wreckage and messages from our alien masters.’
And it’s not just the mummy itself that has raised eyebrows among sceptics.
Jamie Maussan, an ex-investigative journalist who is infamous for his involvement in several high-profile UFO hoaxes, was part of the Peruvian mummy team.
In May 2015, he promoted photographic slides claiming to be pictures of an alien recovered from the Roswell flying saucer crash of 1947.
They were revealed to the world at a conference in Mexico, where he charged £15 ($20) for people to watch a live video stream of the event.
The slides were said to have been thoroughly researched yet they were soon discovered to be pictures of a mummy in a museum exhibition.
‘Jamie Maussan is infamous for promoting dodgy UFO videos and alien artefacts,’ Mr Watson said.
‘He has cried wolf too often to be ever taken seriously by anyone with at least one functioning brain cell.’
