One scientific challenge young earth creationists have had to address is the starlight-time question.

It is interesting to put together all the data. Isaiah 28 mentions learning, teaching, doctrine and knowledge. It mentions line on line, here a little and there a little, and precept on precept. This is how we come to truth in mathematics—in a proof of a theorem, we see line upon line and concept used to prove another concept. Math builds on itself.

For example, we generally learn to crawl before we learn to walk. And, it is often necessary to put all the relevant information together to come up with the best interpretation. We have all heard of the blind men who examined the elephant. Alone, in isolation, they came to erroneous conclusions. This is because they had only a part of the data. Missing information was the problem. One thought the elephant was like a fan, because he had examined the ear. Another, however, who had examined (by touch—remember, these were all blind men) the elephant's leg, said the elephant was like a tree. Well, the part of the elephant that each man examined was as he found it, but that was not all there was to the elephant.

It does seem that we have been jumping to conclusions a bit too quickly in some areas, and in evolution in particular. For example, some scientists have said that dinosaurs evolved from birds, and others that birds evolved from dinosaurs. One must wonder, if there is room for such difference of opinion among scientists, whether the evidence is actually all that clear-cut and conclusive, after all.

The bodies of living things are what evolution tries to explain. But what about behavior? Within the evolutionary model, the only possibility is that behavior results from the chemicals, cells, and components of the organism's body. And what about soul? Spirit? Mind? Likewise, these things are viewed in evolution, if they are dealt with at all and not simply ignored, as simply results of chemical or other natural processes in a body.

Is there any evidence for anything beyond the body? Something involved in the operation of our minds? Something that transcends the simple mechanics and natural forces involved in the matter composing our bodies? If so, then this would be something unaccounted for by evolution. If evolution is true, then evolution must have given rise to consciousness. But, first, what is consciousness?

One view that we could take concerning consciousness is that consciousness, or mind, is nothing more than chemical reactions occurring among brain cells. The brain would be analogous to a computer. However, there is a theory that human consciousness is qualitatively different from what computers do. According to this view, something is happening in consciousness that is beyond the ability of science to explain. In particular, this view holds that it is beyond the ability of physics to explain consciousness.
