Doctor Who's depiction of time travel, to put it mildly, is a mess. It makes so little sense, that its hard to have any real idea of what did and did not happen in the final timeline.
Do the Daleks still invade and conquer Earth in the 22nd century or was that event erased during the purge of the Daleks from history during the Time War?
How much does "modern" humanity know about the existence of extraterrestrial intelligence. The Cybermen very publicly invaded Earth as far back as the 1960s (or 70s depending on when those events were actually supposed to have occurred).
Even excluding the stuff from the old shows, even the modes incarnation of the series seems to be all over the place when it comes to aliens on Earth. UNIT has been in existence since the 60s and Torchwood had been around since the 19th century (yet both manage to be both secret and oddly public at the same time). From "Aliens of London" to the various Christmas incidents Aliens have been shown publicly several times (and been on the news). Planets have appeared and the Earth has been moved. Yet strangely both Torchwood and Doctor Who keep showing us a modern and near future Earth where people are SHOCKED at the existence of Aliens. Torchwood: Children of Earth and Miracle day almost seem to have taken place on separate planets given that the CIA was apparently unaware of Torchwood or aliens. That would seem odd given the existence of UNIT, the fact that the President was ASSAINATED by an alien on the Victory and that the US government and public were aware of what happened during Children of Earth.
