For some reason the theory of evolution seems to raise the hackles of some fundamentalist Christian groups. Other Christians accept the theory of evolution and still find room for God in their worldview. I certainly don’t want to speak for either group, but perhaps the side that each group comes down on is directly correlated to how strictly they interpret the Bible. Because if you literally believe that God formed Adam from the dust of the Earth on the sixth day of Creation, and Eve maybe in the late afternoon from one of Adam’s ribs, then it’s probably got to be nigh impossible to also believe that humankind evolved. And if humans didn’t evolve, then the whole theory has to be wrong.
The human brain does a pretty good job with cognitive dissonance. But two ways the human race came into being? It’s too much, and it would force a person to reject something. Hm. What to choose. Reject God? Nah. Too drastic. Reject Christianity? Nah. Too scary. Reject the literal interpretation of the Bible? Nah. Too chaotic. Reject evolution? There you go. And science itself is responsible for providing the weasel words to make it all possible: it’s only a theory.
