Q tossed the E-D into the path of the Borg.
This gave the Borg knowledge of the UFP. The Borg later ran a couple of attacks on the UFP, trying to assimilate Earth. If not for Q's fooling around, they would not have known of the UFP, and even if they had, they probably wouldn't have considered them a priority target.
The Borg's attack on earth which was met by a UFP fleet at Wolf 359 directly led to Benjamin Sisko being assigned to Terok Nor, the newly rechristened Deep Space 9. Which posting led to his "destiny" and stuff with Bajor and the prophets.
Thoughts?
