"Ben 10,000 Returns reveals that Kenny lives in a parallel future (hence the reason the original Ben 10,000 didn't remember meeting his younger self or the fact that Kevin turned over a new leaf)."

Ben 10,000 Returns is a very important episode explaining that ALL the futures are alternate. the first live action film Race Against Time was even confirmed as an alternate timeline. The games are alternate timelines too.
