Ok so heres my thoughts, there were time travel attempts before Cole was sent back so #1 the thousand year old corpse that the plague is derived from is the remains of a earlier attempt by Jones to send someone back therefore ultimately causing the plague (paradox) #2 Olivia's father is was also a time traveller and that's where he got his fore knowledge and passed it on to her and also why she doesn't age. Possibly one of the previous attempts by Jones or somebody that hasn't gone back yet.
