This unnatural cube-like cloud has the internet scratching its head.

31-year-old Megan Coombs, a mother of two, spotted a strange cloud while hiking in the Devil’s Punch Bowl, a highly sought-after natural reserve in Surrey, south-east England.

The cloud was of a strange cube-shape, with regular lines that made it look like a box.

The images, which were also shared on Facebook, caught the attention of Megan’s friends, with one of them joking that she would think she was seeing fake pictures if it hadn’t been Coombs who shared them.

Some commenters suggested it could be alien in origin, a kind of drone cloud, while others brought up the simulation theory, saying it was a “glitch in the matrix”.

The most obvious explanation, of course, is that it’s just a cubic-shaped cloud, nothing more.

What do you think?
