Debris and Oil not from missing Air France Plane

I still do not understand how an airplane can just disappear! The debris thought to be from the airplane has been determined to be from something else. The oil slick thought to be from the plane was more than would have been. I want to know what is dumping that much oil in the ocean? I am still going with the theory that the plane has been lost in the bermuda triangle and is on an island with polar bears. KA says they are probably with Amelia Earhart!
