The Idea behind this question is to determine others' opinion as to the flow of events.
From the 900 year old Doctor's time stream, he used their own post-hypnotic suggestion. Hence, the humans were able to rebel. Those ghostly, white creatures start the order and then went back in time to stop the Doctor.
Another view is that the "Order of the Silence" is a governing body, a Theocracy, of the Universe. They were always "here", and decided to eliminate the Doctor.
