Howling:If the doctor never existed...

when the doctor was errased in the big bang (tbb), how could there still be a universe for amy to live in to remember the doctor back into existance, since if he didn't timelock the last great time war (lgtw) then rassilon would have destroyed the universe, amoung other things the doctor will never have saved the universe from?

Same reason Amy can still exist even though her parents never existed-when the cracks erase somebody, they don't erase that person's impact on the universe. If it did, then the Time Lords destroying the universe wouldn't be a huge problem. Look at Turn Left and see what the effect is on one planet, when the Doctor's only been dead for two seasons. Now, imagine if he was never born. His impact throughout history remained intact, even though he never existed. Just how that works is anybody's guess.Icecreamdif talk to me 06:52, October 19, 2011 (UTC)

It's arguable that, if the cracks had erased the Doctor's impact on the universe, they'd have erased themselves. Without the Doctor, no Doctor's TARDIS to explode, therefore no cracks caused by the explosion -- and, also, the universe wouldn't have been destroyed by the explosion. --89.240.241.19 14:08, October 19, 2011 (UTC)
