Long time readers of this blog will recall the famous banana argument for the existence of god put forward by an evangelist named Ray Comfort, accompanied actor by Kirk Cameron. The design of the banana is so exquisite, he said, that it could not have evolved according to Darwinian natural selection. He asserted that the existence of the banana was the ‘atheist’s nightmare.’ (This clip has to be seen to be believed. Move the cursor to the 3:25 minute mark to get to the good stuff.)
Well, another ‘atheist’s nightmare’ has surfaced, this time to show why life could not have originated naturally by the action of energy on inorganic matter. The evidence? To appreciate it, you have to move from the fresh fruit section a few aisles over to where the peanut butter is.

Oddly enough, the argument used in this video is the very same ‘absence of evidence is evidence of absence’ argument that I wrote about before, but used incorrectly. There is so much wrong in how this reasoning is used here that one scarcely knows where to begin.
But what I would like to warn the person in the video who is making the case based on peanut is that this kind of argument can be fatal, not for atheists (unless they get a heart attack and die from laughing), but for religious beliefs, because it falls into the trap of ad hoc thinking which can be so easily demolished.
From back when religious believers realized that they could not assume that the idea of god was obviously true and needed some supporting evidence, they have cast around for things that they thought ‘proved’ some religious idea. Initially they have sought to provide evidence of things that could not have occurred except for the action of god.
First it was “Look, the human being! It is so perfect that it has to have been created in the image of god.” Then later it was “Look, the eye! It’s so perfect it cannot have evolved!” And when that fell apart, it was intelligent design creationism with its more sophisticated “Look, the bacterial flagellum!” Now it is degenerating to “Look, the banana!” and even “Look, its Skippy extra smooth peanut butter!”
The flaw is that the proposers of these ideas never seem to explore the implications of their ideas and this is where they differ fundamentally from the scientific approach. All scientists realize that any idea to explain anything has consequences that extend well beyond the thing being immediately explained, and that these consequences must be investigated.
Charles Darwin’s idea of evolution by natural selection is quite simple and the main argument can be stated in a few hundred words. But his groundbreaking book On the Origin of Species consists of nearly 500 pages where he carefully explores a huge number of the possible consequences of that idea, looking both for corroborating evidence and for weaknesses in his theory. He examines animals, birds, insects, fish, and plants from all over the world, looking for patterns. It is an exhaustive and encyclopedic effort, of which I will write more later.
The person making the peanut butter argument has obviously not thought things through. If he thinks that finding an organism in a peanut butter jar or in any other processed food item is evidence of how life originated without god, then he has lost the case because I think almost everyone has at some time bought some item of food that seemed to be ‘spoilt’, i.e., contaminated by some bacteria. We put this down to a fault in the manufacturing process. It is not unknown for foreign matter to creep into food products, and court cases resulting from such events are legion. But for this person, such an event would be a sign of life being created by the action of energy on matter, without the need for god.
I wish it were that easy to show how life originally came into being. Then all scientists would have to do is fan out into the world’s supermarkets and systematically examine each jar of processed food to see if any living organism is found. But instead scientists continue to do it the hard way, in the laboratories, under controlled conditions.
