Ozpin being the first human would be amazing, but like you said... highly unlikely. He does seem wise beyone his years (or any years, for that matter), but I cant see him as that old.

However, to give some cannon support to your guess: Remember Pyrrah's speech when she unlocked Jaune's Aura (one we can assume is always used in said ritual)?

"We will be... infinite in wisdom and unbound by death..."

Sounds like Ozpin to me. Maybe he wrote that? Again, it's unlikely, but it would be awesome!
