And therein lies the moral dilemma for the materialistic evolutionists. The fact is that all life is composed of rock. So we have a choice. We can believe we are descended from the rocks and therefore are nothing more than walking talking rocks, or we can believe that we have ascended from rocks by the process of being created out of the dust of the ground. If the former, then our lives are no more intrinsically valuable than the chemicals which inhabit our physical shell. If the latter, if we are the creation of God, then our worth is derived from the fact that we are made in the image and likeness of God, our creator.
If in the beginning... chemicals, then we are no more valuable than the rocks from which we descended. If, in the beginning... God, then our worth is determined by the one who formed us from the dust of the earth into his image and likeness.
I find it interesting that many who declare the former behave as if they believe, but are in rebellion against, the latter. As an example, they attribute selfishness to the gene while declaring that the mind/soul/spirit is an illusion. And they dont credit their discoveries to their composite matter but rather to themselves.
