Forum:Explanation to devil fruits

has it ever been explained how devil fruits were created or where they originated. Like it just occured to me what if they originated on Raftel because fruits grow on trees and you know .. theres trees on islands. Idk sounds far fetched because that would mean they had somehow got to to the others islands.

Dr. Vegapunk created them.

if Vegapunk created them then Vegapunk must be well old because brook got his power over 50 years ago
