A perfect god would have stopped natural disasters and have surpassed all evil. Yet things like school still remain. This is strong evidence for atheism. Christianity says it was due to free will, where humans decided to do what they want. However, why was there even a bad apple in the first place? If God was perfect, how could he have caused a highly dangerous item to appear? That is quite unexplainable. Thus, I believe this pretty much shows there is no perfect, omnipotent, and omniscient God.
