In science, the term “theory” refers to a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment. Theories must also meet further requirements, such as the ability to make falsifiable predictions with consistent accuracy across a broad area of scientific inquiry, and production of strong evidence in favor of the theory from multiple independent sources.

The biblical stories were presented to me, but they never seemed reasonable. I remember asking about Noah’s ark. Did he look after the invertebrates: the bees, for example? What about the yellow-jackets? And, the black wasps that stung me a few times? All those ants? There’s no mention of the most numerous organisms in my world. As a kid, I remember imagining a series of barges full of soil to be pulled like trailers behind this big boat. Grownups explained that it was just a story (whatever that meant). I remember asking, what was the point of the story? What was this guy’s idea to get animals two-by-two? What did he hope to accomplish, if all the bees, worms, oak trees, and rosebushes were gone? Let alone the question: why did he let the poison ivy come back? He missed a huge opportunity, etc. It was never satisfying to my mind.
