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 cinema have started (and stopped) wars, terrified millions, and inspired religions throughout the world.

| 0:51.0 | Right now, Greg, I need a definition. What is a complex organic molecule? |
| 0:57.0 | Well, a complex organic molecule is a molecule that contains carbon, usually some hydrogen bonded to it. |
| 1:04.0 | And then when it becomes complex, I guess it gets a little bigger than just carbon and |
| 1:09.3 | hydrogen. |
| 1:10.3 | So you know, the definition is quite fuzzy about what complex means, but it just means something that's got a little bit more to it than just carbon and hydrogen, I guess. |
| 1:19.0 | And the reason we're looking at them is because the word organic is highly suggestive. However, we don't |
| 1:26.7 | have the at this point we don't have the formula that we need to put together organic molecules, amino acids, and meteorites. |
| 1:38.6 | But it would appear that you have the elements for it. |
| 1:41.6 | That's from reading your reporting you don't go any |
