Well, at least you are been honest
You are right on the part that "evolution" is observed and tested on the very limited scale, that all living organisms are able to adopt to the environment in some limited way. As I said early, in software engineer terms this is called a configuration change, i.e. programs that pre-configured to handle certain situations by adjust per-configured parameters.
Once the change is out of the pre-configured parameters, the program will crash (i.e. when mutation happens, most are bad ones that result in different deformations of the host and the host usually dies).
What evolution was suggesting (The original book by Darwin, "On the Origin of Species"), is that those minor changes will gather and eventually result in something totally different, i.e. fish gradually evolve to have legs and then have wings. What I am countering with is, that could never happen, and if you look back on the fossil records, you see fish, then something with short legs that still looks like fish, etc, but you never see the in betweeners where the legs are very short, then gradually got longer, that fill the void between them (evolution should be gradual right?). All that strongly indicates creation, i.e. species were created, then the creator gradually improves upon them (or modify them to try out how the result will look like), the step are much bigger than a slow evolution as suggested by ToE.
