Aliens are Out There, and they're interfering in our lives. This interference manifests in various different ways - most commonly, unexplained and bizarre mutilations and eviscerations of livestock, particularly cattle; crop circles and other strange phenomena, particularly in rural areas; and abduction of human “samples” to experiment upon. Theories on the true purpose behind these behaviours range from petty sadism, to scientific experimentation, to an obscure attempt to communicate.
