Strange UFO patterns have baffled passers-by taking a stroll on a Pembrokeshire beach - one of the UK’s most renowned UFO hotspots.

The mysterious markings appeared etched into the sand at Broadhaven Beach, with the cipher surprising locals and visitors alike with its ancient hieroglyphic style and cryptic message spanning the shoreline.

It showcases a six metre-wide skull at the centre and contains a central cipher code written by Dr Jonathan Melville from MIT, which is waiting to be solved [https://beavertownbrewery.co.uk/blogs/land-of-cool/beavertowns-halloween-sand-cipher].

The markings, which appeared just in time for Halloween, were created by Beavertown Brewery, after research revealed 42 per cent of Brits would try and communicate with aliens if they ever landed on Earth.

Dr. Jonathan Melville said: “Many ancient cultures used circular symbols like Norse runic circles and Hindu mandalas, but some elements in this design are historically out of place and prove to be more modern.

“The ancient Celts had no knowledge of modern computer structures or telegraph codes, nor did they require it - which is why this design almost seems as if its creation has a non-human origin.

“This code is tailored for those who possess a deep curiosity and urge to unveil extra-terrestrial messages - only the truly intrepid would muster the courage to decode its secret meaning.”

The study of 2,000 adults also found 34 per cent believe aliens exist, with 15 per cent claiming they have actually met someone who says they have seen one in real life.

Compared to other unproven beliefs, people have expressed greater certainty in the existence of extra-terrestrial life than they do ghosts (29 per cent) or even heaven (28 per cent).

Reasons for believing in alien existence include 86 per cent thinking the universe is so big there must be other life forms, while a quarter based their views on news stories.

And 37 per cent like the idea that aliens could exist - regardless of whether they believe it or not.

It also emerged 56 per cent of adults think it's likely that the government is hiding the fact that aliens exist.

If they were to ever meet one, 33 per cent would be intrigued, but a fifth admit they would feel terrified.

And, according to the OnePoll data, 42 per cent would try to communicate with them if they ever landed on planet Earth.

Brewery has also teamed up with Black Dog Films' Alice Bloomfield to launch 'Flightmare' [https://www.youtube.com/watch?v=4x7EzB_TIKo] - an animated short film and graphic novel inspired by strange happenings in the Bermuda Triangle.

Tom Rainsford, at Beavertown Brewery, said: “Pop on the TV or check your socials, it seems everyone is talking about aliens and UFOs.

“Therefore, it’s not surprising that almost half of the UK say they’d try and communicate with an alien if they ever came across one - just imagine the questions you’d want to ask.

“We are big fans of all things extra-terrestrial, so to celebrate Halloween and the launch of our new short film and graphic novel, we thought what a better way than to try to see what’s really out there with a unique extra-terrestrial sand message.”
