Duncan Lunan is an author and astonomer, whose 2012 book ‘Children from the Sky’ explored the tale of the Green children of Woolpit. According to a 12th century folklore, two children – one a boy, the other a girl – were found in Suffolk, England, with skin and hair of a green pigment, dressed all in green and speaking in a tongue unlike any earthly language of the time. Many at the time thought their appearance was supernatural… Marsh and Hayley spoke to Duncan about his investigations into the story, how he thinks the children came to be in 12th century England, and why he believes them to be of alien origin – dismissing the more commonly-accepted terrestrial explanations for the story.
