<p>That still proves there is an afterlife. If Kakashi was dead (and he was, he was revived by Rinne Tensei), and could then talk to his dead father, then there is obviously some level of consciousness beyond living in the Naruto universe. Just because Haku and Zabuza couldn't mark the passage of time, doesn't mean they weren't conscious. Elveonora has zero evidence for his beliefs other than his misplaced real-world bias.
