You are all wrong. What Paradox and Ben did was go back in time in NO WATCH BEN'S timeline, THEN they rebooted the timelines. Why would they go back in time in the main timeline, when Paradox wasn't even the cause for Ben finding the Omnitrix? Why would they need to go back 6 years in time into another timeline, to reboot the timeline, if all they needed to do was literally travel 6 minutes back in time?

Because Vilgax erased all timelines present, past and future, ALL OF IT. Nothing remained, only No Watch Ben's timeline remained, which is why they travelled back in time in his timeline, and gave him the omnitrix, which essentially made HIM the main timeline Ben, since every other Ben and their timelines were erased from existence.
