Indirectly, it would seem that the Xindi were responsible for the creation of the Borg. If the Xindi hadn't attacked earth, Archer wouldn't have needed MACOs onboard Enterprise, and later recommending that Hernandez have some MACOs assigned to Columbia. So the events that led to MACOs becoming the first Borg would never happen.
But then again, since the attack on Earth apparently never happened in the original timelime, the Borg probably shouldn't have existed in the first place .......
Who says there was an original timeline? The attack on Earth, the events of ST:FC, were a predestination paradox. They *always* happened. Certainly can't prove otherwise, can we?
