You can't see nitrogen, so I guess it'll never be a fact that it exists and you breathe it 24/7. You can't see and never will electricity going through the wires in your car audio "build", so I guess there is no proof electricity even exists. You've never seen a **** happen, so I guess you will never believe one actually did happen. You've never seen a billion dollars in person, so I guess there is no proof that such money exists. You didn't see your laptop being assembled, so there is no proof it ever actually was.
Jeez, you are a fvcking weird kid.
