Book excerpt: Follow this multi-disciplinary, scientific study as it examines the evidence of a great global catastrophe that occurred only 11,500 years ago. Crustal shifting, the tilting of Earth's axis, mass extinctions, upthrusted mountain ranges, rising and shrinking land masses, and gigantic volcanic eruptions and earthquakes--all indicate that a fateful confrontation with a destructive cosmic visitor must have occurred. The abundant geological, biological, and climatological evidence from this dire event calls into question many geological theories and will awaken our memories to our true--and not-so-distant--past.
