• the earth would have existed for about
• five years 4.5 billion ys
• large organisms with many cells for
• 7 months 600 million ys
• the asteroid that killed the dinosaurs would have
  landed
• 3 weeks ago 67 million ys
• Hominines would have existed for just
• 3 days c. 7 million ys
• our own species, Homo Sapiens, for
• 53 minutes c. 200,000 ys
• agricultural societies would have existed for
• 5 minutes c. 10,000 ys
• the entire recorded history of civilization for
