It's either aliens or witchcraft. Or the smoke monster from Lost.
Pierce Smith caught the mysterious ring flying over his house yesterday and we think it's safe to say his fear was justified. Many commenters have been saying that it's merely a smoke circle, but who creates smoke circles in the first place?
To be honest, we're not 100% sure this isn't a hoax, but seeing as the UK has been rife with UFOs lately we're either well into an alien invasion or someone's let some nanobots loose and we're all about to be taken over by them. That or God is smoking one hell of a cigar.
