"We are unique, therefore it must be a divine plan"? That's essentially your argument. Yes, we do have a far greater capacity for moral reasoning, which from a Darwinian explanation, has evoloved from our developed consciousness and brain formation. Our morality is a part of us, just like our instinct and consciousness. To explain our morality by resorting to the supernatual has not advanced the discussion by one inch.
Must we explain our consciousness on Darwin's theory? One cannot say that these set of laws, universally embraced by all humans in the form of the conscience can be simply explained away by Natural Selection.
Firstly the fact that this morality + ethics are universal in all humans, ranging from pre-historic cultures to the contemporary world is startling. Our conscience has evolved from vastly differring environments, both culturally and physically different. This in itself defys Darwin's explanation, as the environments of a species differ therefore the another species should be formed.
Moreover, Darwin's theory should not be applied in social circumstances. His theory for natural selection was developed for the "unconscious" so to speak. In our society, the crippled is not left to die on the streets. And there are terrible effects stemming from the social application of Darwinism, i.e. Hitler's Facism, where the blue eyed blondes were nominated to overpower world. Humanity's consciousness is unique, and trascends beyond Darwin's theory, and arguably science in itself.
The second thing we must ask ourselves is this, why does this system of morality exists within our conscience. Why must we perserve human life, pretaining to those laws within our mind? Lets take the example of being unselfish. As C.S Lewis once answered in his book
Mere Christianity, 'Because it is good for society,'. But he continued to question, 'Why should I care what's good for society except when it happens to pay me personally?' The answer to that is 'Because you ought to be unselfish'. The result is a everlasting chain of truths, that does not answer our question.
So from my perspective, I find that the existence of a conscience, if you like a set of "Moral Laws" as Lewis puts it is ever against rationality. And it leads to the conclusion for me, that there exist a God.
However, I am happy for those to refute my claims.
