At multiple points throughout week one, God declared His work “good.” When He gathered the waters together to make dry land, God saw that it was good (verse 10). When He made plants and trees yielding seed and bearing fruit, God saw that it was good (verse 12). When He set the sun and moon to rule the day and night, God saw that it was good (verse 18). When He created fish and fowl, God saw that it was good (verse 21). When He made livestock and insects, God saw that it was good (verse 25).
As He prepared the earth for life, specifically life for His image-bearers, God pronounced His own approving evaluation of creation’s goodness. That is, God declared creation’s beauty and quality and acceptability and desirability. (As a side note, setting up the earth for life is not the same as making little-life and causing it to mutate into more complex life.)
Then, God saw everything that He had made, and behold, it was very good (verse 31). There was nothing about His creation that was deficient or defective or hurtful. So here’s the question: if killing and death prevailed on the planet, with weak and mutant and in-between-stages creatures, as evolution requires, how could God claim “everything was very good”? Theistic evolution must imply that death is an acceptable good, that as long as the fittest survive and overall progress is being made, everything is okay. But in biblical terms, that is a very bad kind of good, and really no good at all.
