Brian Hoffstein puts it in perspective:
Hypothetically, if our 14 billion-year-old universe were scaled down to just 10 years (for the sake of comparison), dinosaurs would have been extinct 17 days ago, our earliest relative Lucy would have been playing around on the Savannah 19 hours ago, modern humans would have first appeared 80 minutes ago, the birth of Jesus just 46 seconds ago, and the declaration of independence would have been signed a mere 5 seconds ago! Think about that for a moment: what does 5 seconds mean to you in the scope of 10 years?
