Long time ago, I dreamt about wheels...
Years later, I saw one being made and got a deja vue feeling.
Using my dream and my observation, I made my own version of wheels.
Am I a thief now?
Is it ethical for a tribe to claim sole right on the use of wheels, just because they were the first to make one?
If that tribe would come over to destroy my wheel to protect their copyright, would'nt I be allowed to defend my creation?
