The fact of the matter is that the fossil record not only documents evolution, but that it was the fossil record itself which forced natural scientists to abandon their idea of the fixity of species and look instead for a plausible mechanism of change, a mechanism of evolution. The fossil record not only demonstrates evolution in extravagant detail, but it dashes all claims of the scientific creationists concerning the origin of living organisms.
Well, evolution is a theory. It is also a fact. And facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world’s data. Theories are structures of ideas that explain and interpret facts. Facts don’t go away when scientists debate rival theories to explain them. Einstein’s theory of gravitation replaced Newton’s in this century, but apples didn’t suspend themselves in midair, pending the outcome. And humans evolved from ape-like ancestors whether they did so by Darwin’s proposed mechanism or by some other yet to be discovered.
Ultimately the Darwinian theory of evolution is no more nor less than the great cosmogenic myth of the twentieth century. Like the Genesis based cosmology which it replaced, and like the creation myths of ancient man, it satisfies the same deep psychological need for an all embracing explanation for the origin of the world which has motivated all the cosmogenic myth makers of the past, from the shamans of primitive peoples to the ideologues of the medieval church. The truth is that despite the prestige of evolutionary theory and the tremendous intellectual effort directed towards reducing living systems to the confines of Darwinian thought, nature refuses to be imprisoned. In the final analysis we still know very little about how new forms of life arise. The “mystery of mysteries” — the origin of new beings on earth — is still largely as enigmatic as when Darwin set sail on the Beagle.
The probabilistic teleological argument exploits the idea that it is extremely improbable that the laws of the universe should be so balanced as to permit the development of life unless we adopt the hypothesis that these laws were fixed by a creator who desired the development of life. The argument, however, faces the same kind of objection as the one we brought against the cosmological argument in the previous chapter: it takes a certain concept out of a context in which it is obviously applicable, and applies it to a context in which that concept is not applicable. In the case of the cosmological argument, the crucial concept is that of causation; in the case of the teleological argument, it is statistical probability. Neither argument carries conviction because we can plausibly deny that the concept in question can be extended to cover extraordinary contexts.
Suppose you become convinced that all your choices, decisions, and conclusions were determined by rationally arbitrary features of your psychological makeup or by external manipulation, and then tried to ask yourself what, in the light of this information, you should do or believe. There would really be no way to answer the question. Because the arbitrary causal control of which you had become convinced would apply to whatever you said or decided. You could not simultaneously believe this about yourself and try to make a free, rational choice. Not only that, but if the very belief in the causal system of control was itself a product of what you thought to be reasoning, then it too would lose its status as a belief freely arrived at, and your attitude toward it would have to change. ¶ Doubt about your own rationality is unstable; it leaves you really with nothing to think. So although the hypothesis of nonrational control seems a contingent possibility, it is
no more possible to entertain it with regard to yourself than it is to consider the possibility that you are not thinking. I have never known how to respond to this conundrum.

God does not exist if Big Bang cosmology, or some relevantly similar
theory, is true. If this cosmology is true, our universe exists without
cause and without explanation. There are numerous possible universes,
and there is possibly no universe at all, and there is no reason why
this one is actual rather than some other one or none at all. Now the
theistically alleged human need for a reason for existence, and other
alleged needs, are unsatisfied. But I suggest that humans do or can
possess a deeper level of experience than such anthropocentric
despairs. We can forget about ourselves for a moment and open ourselves
up to the startling impingement of reality itself. We can let ourselves
become profoundly astonished by the fact that this universe exists at
all.
Religious experiences are like those induced by drugs, alcohol, mental illness, and sleep deprivation: They tell no uniform or coherent story, and there is no plausible theory to account for discrepancies among them.
If you look up ‘atheism’ in a dictionary, you will probably find it defined as the belief that there is no God. Certainly many people understand atheism in this way. Yet many atheists do not, and this is not what the term means if one consider it from the point of view of its Greek roots. In Greek ‘a’ means ‘without’ or ‘not’ and ‘theos’ means ‘god.’ From this standpoint an atheist would simply be someone without a belief in God, not necessarily someone who believes that God does not exist. According to its Greek roots, then, atheism is a negative view, characterized by the absence of belief in God.
Now it is often seems to people who are not religious as if there was no conceivable event or series of events the occurrence of which would be admitted by sophisticated religious people to be a sufficient reason for conceding ‘there wasn’t a God after all’ or ‘God does not really love us then.’ Someone tells us that God loves us as a father loves his children. We are reassured. But then we see a child dying of inoperable cancer of the throat … Some qualification is made — God’s love is “not merely human love” … perhaps — and we realize that such suffering are quite compatible with the truth of the assertion that “God loves us as a father …” We are reassured again … I therefore put … the simple central questions, “What would have to occur or to have occurred to constitute for you a disproof of the love of, or the existence of, God?”
If it is to be established that there is a God, then we have to have good grounds for believing that this is indeed so. Until and unless some such grounds are produced we have literally no reason at all for
believing; and in that situation the only reasonable posture must be that of either the negative atheist or the agnostic. So the onus of proof has to rest on the proposition [of theism].
