David Wilkinson has made an extensive survey of the data and the possibilities for extraterrestrial life, including
-- the evidence for life on Mars
-- the discovery of other planets that could sustain life
-- attempts to detect alien messages
-- UFOs and alien abductions
-- government conspiracy theories

He carefully weighs the facts and examines the scientific arguments for space travel and for life developing elsewhere in the universe. He also considers claims that the Bible actually describes alien encounters from the past. And if life does exist elsewhere, he asks, does that mean that human beings do not have a special relationship with God or that Jesus' life and death did not have universal significance?

Analyzing our interest in alien life from Star Wars to The X Files, from science to speculation, David Wilkinson offers a convincing answer to the question "Are we alone in the universe?"
