How about...
The Slitheen were paid by [insert your villain of choice here] to destroy the Earth because that would remove it from the timeline.
I mentioned somewhere that the only way to destroy Gallifrey would be to attack it in several times at once - creating unmanageable paradoxes.
If Earth is the lynch-pin of the future (cradle of civilisation etc.) then it's removal would give another race the chance to seed the universe.
If we look at The End of the World, the timeline seems OK. Our villain [insert your villain of choice here] decides that the human race SHALL NOT become the dominant species. So he/she/it goes back to several key points in Earth's history in an attempt to find a weak spot in the timeline:
1869 with the Gelth
2005 with the Nestene
2006 the Slitheen
200000 the jaggedlyspeckledgooglewhatsitofthejaffacake (or somesuch)
Luckily the Doctor - perhaps guided by some higher force (which would explain the TARDIS going off course) - is always there to thwart [insert your villain of choice here]'s evil plans.
Any thought's?”
The Slitheen deliberately targetting Earth: this is looking more and more likely as the series progresses. There's obviously more going on in each episode than meets the eye. BG thinks there could be a consortium of businessmen, I originally thought the Master would be involved (I still wouldn't be surprised) and Alrightmate/yourself think it may be Fenric (if I remember rightly?)
I also agree with Alrightmate's ideas that this series is very much 'of the day' and would be willing to bet that the people behind this trouble would be terrorists - time terrorists? Which leads us back to Faction Paradox (although they may not have that particular name in this new series.)
I don't know whether the Tardis is deliberately going astray due to some influence or it's just the Doctor's erratic ability to control it properly. If it is deliberate, then we should be expecting to see the Guardians reappear later in the series (possibly at the end if the destruction of Gallifrey is reversed). If not, then I'm not sure where this leaves us.
I'm not sure about the Guardians - I don't know if RTD would want to delve that deeply into the history of the classic series at this point
Since we have a 'money is the root of all evil' theme going on, maybe the terrorists are sponsored by the consortium (indirectly of course - nothing that could leave a trail).
Regarding the destruction of Gallifrey, wouldn't another way of destroying it be to go back before it's creation and destroy it then? (OK, I know we have the transduction barriers, but if they were lowered or destroyed by a traitor then wouldn't that be possible too?)
Even Timelords are forbidden to go back into Gallifrey's past in case they alter something and prevent the Gallifreyan discovery of time travel. (another part of Blinovitch I think?).
I need to think about this some more.
