The fact that humans are smarter gives them an edge over the . Similarly one may ask, where is the crater that killed the dinosaurs? (The closest comparison in human experience is a nuclear explosion, but the energy release of the Chicxulub impact was on the order of 100 million megatons, while the largest bomb ever tested yielded about 50 megatons.) It was formed when a large asteroid, about 10 kilometers (6.2 miles) in diameter, struck the Earth.
