Doctor Who: 10 Major Ways The Doctor Affected Human History

10. Hijacking The Moon Landing Broadcast

One of the only examples of the Doctor actually utilising a historical event to help them win the day, the bad guys in Series 6's blockbuster two-part opening were defeated with a little help from Neil Armstrong... and his foot.

With the Silents having infested pretty much every last corner of the Earth, the Doctor devises a surprisingly violent way to deal with them, for someone who claims to be a pacifist: he convinces humanity to mercilessly slaughter them.

That's uh... that's one way of doing it.

With a clip of a Silent saying, "You should kill us all on sight" spliced into the broadcast of the moon landing, any human who watches that iconic historical moment will now see a Silent instructing people to kill them. This clip could be in the real broadcast too, and we'd never even know it. Spooky. If you ever feel a murderous urge out of nowhere, that might be it.

Did the Eleventh Doctor care that he'd basically turned billions of humans into murderers? Since he was snogging River immediately afterwards, probably not. But hey, his plan was an effective one!
