The Offical God FAQ is neither scientifically nor logically accurate. Science cannot prove that something does not exist. Logically it is not accurate for if you say there is no God, then that means you know absolutely everything which then makes you God.

A true scientist, if he is to be honest, can not answer that question with a “no.” He may answer it by saying he is unable to determine the existence of God – but never can he make a definitive negative answer.
