Are you in KS? What part?

JStark,
Would you agree that evolution deals largely with evidence that is circumstantial in nature, since no creature has ever been directly observed to evolve into another creature?

This is not, I think, an accurate representation of the position most IDers take.
Neither evolution nor ID have much in the way of direct evidence to work with since neither has ever been directly observed.
The evidence that is available to evolutionists and IDers alike is largely circumstantial in nature. As such it is open to a variety of interpretations.
Most evolutionists hate to admit that this is so, but until they can show direct observation of evolution, this is where we are.
For evolutionists to present inference and circumstantial evidence as conclusive is, I think, a bit too optimistic on their part.
That is very silly reasoning. We have never seen a mountain created by 2 tectonic plates crashing together but it is well established based on other evidence that it has occurred. We didn't see the Grand Canyon created by erosion but the science supports that it was created that way. We haven't seen the polar ice caps or glaciers created but it is well known that they are caused by precipitation. We didn't see the sedimentation that created sandstone but that doen't mean we don't have a clue how the rocks were formed. We didn't see the formation of oil and coal but we have a good idea how that happened.
Every branch of science often takes small observed changes and extrapolates over long time periods. We have seen DNA change. We have seen species become unable to have offspring with other descendents from a common ancestor. We have seen NOTHING observable that relates to an intelligent design. There is quite a difference in the science behind ID and evolution. They are in no way comparable unless you ignore the standards of science completely.

How exactly would you expect to witness such an event? Please explain what you mean. What exactly would we be witnessing?
We do have fossil records that show evolution has been at work. We can witness it's effects through time that way.
Evolution is not anymore circumstantial than quantum mechanics.

However, we have NO direct observable evidence of one creature becoming another, nor anything even close. Not even close to close.
What we have is fossils that show that animals which were alive are now dead.
Finding fossils of two creatures who share many characteristics and diverge on a few others is NOT proof that one evolved from the other or that they come from a common ancestor. That is an inference only.
There are other POSSIBLE interpretations of them as well.

We have direct observable evidence of erosion making canyons.
We have direct observable evidence of continents moving.
We have direct observable evidence of large amounts of precipitation in the polar regions.
However, we have NO direct observable evidence of one creature becoming another, nor anything even close. Not even close to close.
The changes we do observe in creatures by way of mutation are almost always harmful, not beneficial. So most of the direct observation that should take us in the direction of evolution (according to the theory) instead takes us in the other direction.
Evolution is only a certainty if you ignore the standards of science completely.

We can observe genetic mutations, and we can observe heritability. That is evolution. Genes determine a creature's physical characteristics, and genes are passed on from parent to offspring. Genetic mutations occur, creating new physical characteristics - if one of these characteristics is beneficial, the animal is more likely to survive and reproduce, so the gene is more likely to survive. As this occurs over many many years, species gradually change, and adapt to their environment. Evolution.
If we can observe genes, genetic mutation, and survival of the fittest, we can observe evolution.
The great majority of mutations are not beneficial. They are harmful or neutral, advancing the species not a bit.
Even the ones that can be said to be beneficial (how many mutations would it take to generate an eye where none existed?) often have no benefit until and unless many other mutations (the other necessary components of the structure, it's processes, it's maintenance and defense) are existing as well.
Also, slight advantages may (or may not) tend to help survivability but in no way insure it. The fittest do not ALWAYS survive and thrive. If a beneficial characteristic is lost due to the death of the member that carried it , then you must suppose that the same beneficial characteristic showed up by blind chance AGAIN in the same species.
Since populations of species , especially of the higher animals, tend to be much smaller numbers than , say insects or bacteria, the likelihood of this characteristic reappearing is greatly hampered. And it is in those same higher animals that evolution requires huge changes in body style, function, etc to develop the huge variety represented by such diverse groups.
Also as these creatures supposedly diverged from one another, the failure to interbreed with old stock would, each step along the way, repeatedly by definition reduce the population of each 'new species' to a very low level, increasing the risk of losing new characteristics if one or a few members of the newly diverged species perished.
These repeated instances of small populations are a huge problem for evolution which NEEDS very large populations to make a go of it.

Evolution is not about the survival of the fittest per say. It's mostly focused on the survival of the fit. There need not be only one, hence variation. I don't understand what you mean by the rest of the paragraph. Could you explain why a trait that is lost do to death must reappear? The reality of extinction seems to be against this.

Again, I am not understanding what you are saying regarding the reappearance of characteristics. Why must they reapper? As for requiring huge changes in body style, it has been shown that even a fraction of a percent of advantage is significant in evolutionary adaptation. So the changes can be minute.

This is absolutely backwards. A new species that is better adapted to it's environment than the "old stock" would thrive. The old stock would dwindle as it is not as "fit". Thats the point.

I don't see the problem at all because evolution does not make the claims you are attributing to it. Evolution is about adaptation to environment so that a species can thrive, not stay small and dwindle.
Kind Regards
If the creature with the beneficial mutation does not, in reality, benefit enough to insure survival, then the mutation must reappear some other time in another member of the same species. This member must derive enough benefit to survive, or.......it's Groundhog Day. Get it?
Actually evolution does require large populations to "work" and evolutionists will generally admit that much.
a. The theory "postulates an unguided natural process that has no discernable direction or goal."
b. "The view that living things in all the major kingdoms are modified descendants of a common ancestor (described in the pattern of a branching tree) has been challenged in recent years by (i) discrepancies in the molecular evidence, (ii) a fossil record that is not consistent with gradual increases in complexity, and (iii) studies that show that animals follow different rather than identical early stages of embryological development.
c. "New heritable traits may result from new combinations of genes and from random mutations or changes in the reproductive cells. Except in very rare cases, mutations that may be inherited are neutral, deleterious or fatal."
d. "Whether microevolution (change within a species) can be extrapolated to explain macroevolutionary changes (such as new complex organs or body plans and new biochemical systems which appear irreducibly complex) is controversial."
