The Vatican has long been thought to be hiding something very telling when it comes to it - and The Pope's - involvement with alien cover-ups, with continued silence seemingly not helping

For decades, the truth about the Vatican's relationship with aliens has been kept hidden from the public – with officials refusing to comment on it.

Speculation has been running riot about what lies beneath the Vatican's walls, with rumours of alien cover-ups and evidence being kept inside its vaults ramping up in recent years. But the pressure on the Vatican to front up to the claims ramped up last year thanks to a whistleblower.

David Grusch is a US Air Force veteran and has often made claims about the US Government's involvement in covering up the truth about aliens and UFOs. However, last year he brought the Vatican into the fold by claiming that it knows about aliens and was involved in a cover-up as far back as 1933.

He said: “1933 was the first recovery in Europe, in Magenta, Italy. They recovered a partially intact vehicle, and the Italian government moved it to a secure airbase in Italy until around 1944-1945

“The Pope back-channelled that, and told the American's what the Italians had and we ended up scooping it.”

He was then asked by NewsNation to clarify whether or not the Catholic Church was aware of “non-human” existence on Earth, to which he replied: “Certainly.” And when asked why he should be believed, he said: “I have the credentials, and I was an intelligence officer.”

But when probed about the claims, the Vatican refused to respond – and has yet to do so to this very day.

Journalist Ross Coulthart suggested: "It's a very difficult situation for the Vatican because if Mr Grusch is telling the truth, it's a difficult thing for the Vatican to admit without the US concurring. I'm told the Vatican does have a very efficient intelligence service and it's long collaborated with intelligence services like the CIA providing useful intelligence, and especially in the wake of the Second World War."

Coulthart claims to be in touch with people with access to the Vatican’s archives, which consists of 53-mile-long shelves full of documents. Answers to Grusch’s claims may lie there, he added.
