Are aliens and UFOs real? Astrophysicist Hugh Ross, who is also a Christian apologist, has intensely looked at this issue for decades.

Ross became a UFO expert by accident, though his theological take on the issue — particularly in light of the newfound cultural obsession with the topic — is fascinating.

On today's episode of "Billy Hallowell's Playing With Fire," he explores the nature of aliens, why he believes things might not be what they seem, and what people (and, in particular, Christians) might want to pay attention to.
