The Solar System. Dinosaurs. Donkey Kong. What is the missing link? Surprisingly enough, it's meteorites. They explain our past, construct our present, and could define our future. Impact argues that Earth would be a lifeless, inhospitable piece of rock without being fortuitously assaulted with meteorites throughout the history of the planet. These bombardments transformed Earth's early atmosphere and delivered the complex organic molecules that allowed life to develop on our planet. While meteorites have provided the raw materials for life to thrive, they have radically devastated life as well, most famously killing off the dinosaurs and paving the way for humans to evolve to where we are today. As noted meteoriticist Greg Brennecka explains, meteorites did not just set us on the path to becoming human, they helped direct the development of human culture. Meteorites have influenced humanity since the start of civilization. Over the centuries, meteorite falls and other cosmic cinemas have started, and stopped, wars, terrified millions, and inspired religions throughout the world.
