In the early 12th century, two children, a boy and a girl, appeared in the village of Woolpit in England. According to the scant documentation we have, they spoke a strange language that wasn't English and they had green skin. Strangely, they weren't burned at the stake, and the villagers seem to have accepted them. They just assumed the children were fairies, a perfectly logical explanation. When the girl learned enough English, she told a story that made no sense at all. But as we look back at the incident now, there are (at least) three possibilities.
1. They were aliens from outer space.
2. They suffered from a rare but real medical condition that made them look green.
3. In the many years between the incident and the surviving written accounts, the story could have changed a lot, growing like legends do.
