Despite the fact that Apophis needs to pass through a 'keyhole several hundred meters wide' in order to become a serious threat to impact Earth (which seems rather insignificant in an astrophysical sense) this provides humans with the first tangible opportunity to affect their destiny as a species against the previously impervious forces of nature. It has long been thought that dinosaurs perished as a result of a cataclysmic impact from a meteor similar to Apophis, but because of their lack of advanced intelligence they were wholly ignorant of their fate until they were engulfed in an atmosphere that could no longer sustain their ecosystem. Had we faced such a danger even 50 years ago, the human race would have been close to powerless against an impending impact from an asteroid, but because of the great technological progress of the late 20th century, and assuming continued progression at or above current rates, human-beings have created for themselves an opportunity to become the first Earthly species to have complete control over its fate. Remarkable, aren't we?
