Please watch this brief educational film in which Kirk Cameron -- best known as the teenage son and (apparently) Chief Evolutionary Biologist from "Growing Pains" -- has a friend show us why the banana proves the existence of a Supreme Being.
I myself do believe in the existence of God. However, using the same logic presented above, one could prove that since a pineapple isn't easy to open, isn't conveniently shaped, isn't covered by a user-friendly surface, and doesn't fit well in your hand or mouth... that God did not create the pineapple as He did the banana. I knew there was something vaguely unholy about that Hawaiian pizza I had a couple of days ago...
The nifty thing about this is that the banana as we know it today is an excellent example of Intelligent Design. To prove it, I have included a photo of a wild, unmodified banana at the top of this entry. This is what all bananas looked like before hundreds of generations of selective breeding and modification... by humans.
(By the way, a banana is easier to open from the non-stem end. Pulling on the stem is a human convention. Try it yourself. Or watch a gorilla have lunch some time).
The lesson here? Whatever your Dogma is, don't let it become your Truth. At best you may end up being right for the wrong reasons. At worst... you might invade Iraq.
