Fingerprints of the gods

This book is about the beginning of the human race. How perhaps normal history has left things out, or maybe just left things unexplained. **Graham Hancock** explains how certain ancient structures all over the world are much older than originally thought, how civilizations who had no means of travel seemed to have communicated in some way. Hancock tries to answer questions we may have never even thought to ask. Were ancient civilizations visited by a superior race? Were these civilizations taught about technology they wouldn't have had?
