Books like Our Haunted Planet

I listened to this audio-book through Audible.The title is a little misleading, as from it you would think this is a study of ghostly apparitions and the spirit world. In fact this is an in depth collation of otherworldly visitations and UFO sightings from prehistory to the 20th Century. The author certainly weaves an intricate pattern across the world, tying together sightings across many lands and many cultures in an attempt to link the rise and fall of many societies with alien superior intellect/design.I enjoyed the pace of the narration and the timbre of the narrators voice had a resonance to keep me interested in the subject matter (congratulations to Michael Hacker).Although I'm sceptical about this subject, I am also one of those people who firmly believe we can't be the only planet in the entire Universe/Multiverse with life, whether that life is capable of sentience is another matter altogether.
