This question already has an answer here:

At the end of Star Trek: Nemesis Data sacrifies himself by destructing Scimitar(year 2379). I thought he died.
But then i searched for Enterprise F and there I saw written that:

"Captain Data was offered command of the vessel but refused."
(Year 2409).

How is he alive?
