Example  
Form 
Treatment Dealt with by pointing out that just becuase something has not yet been proven true does not mean it will not be or visa versa. You simply cannot draw any conclusion. It took 358 years to prove Fermat's Last Theorem. So for all of that period according to this fallacy you would have concluded that the theorem was false because it had not been proven. Yet in the end Andrew Wiles proved the theorem correct.
