The Ascent of an Inferential Staircase

This supposed demotion of human beings as being created in the image of God proceeds by means of the ascent of an inferential staircase that any thinking person can see is on the verge of collapse. Any cursory examination of the great apes and human beings revealed profound and striking differences, not only in the organism itself, biomechanically, biochemically, but above all in its nature and soul. You're having trouble distinguishing a difference in kind rather than degree between you and a chimpanzee? Here's a simple test that chimps are on the other side of the cage. You're not. It's quick, it's effective, it's operational, and it's infallible.
