Kishimoto never actually confirms the origin of the byakugan. All we know is that the Otsutsuki had it first, and then passed it on to the Hyuga. Personally, I think a good explanation would be that an ancient Otsutsuki ate the fruit of a Shinju Tree, gained the Byakugan, and passed it down through the generations. I could be wrong though. Any theories?
