Well, with all that was said in the 2009 movie, aside from mentioning "Admiral Archer" and his dog, who we don't even know if they were referring to Jonathan Archer or another Archer altogether, there was very little to indicate that Enterprise came before the movie.
I believe it was Orci and Kurtzman who confirmed that the Archer mentioned was indeed John Archer of Enterprise
. Besides, the name drop makes no sense otherwise. Occam's Razor should be wielded here.
The prime universe was not altered until 2233 so Enterprise
occurred as seen on TV. It is the only series that is canon in both universes.
