Because the simple fact of the matter is you are not asking them to change an existing theory or consider a new scientific theory, but to change their religion of evolution.
Evolution is a scientific theory supported by scientific evidence. It is not a religion. Why do you continue to lie about this?
One would expect similarities between kinds, given that 1) the same Creator made them all, and 2) they were all created from the dust of the Earth.
However, we would not expect a nested hierarchy since the Creator of birds and mammals would be free to combine those features for a new species. It is not simply similarities that evidence evolution. It is the NESTED HIERARCHY that evidences evolution.
How many times do we need to go over this?
If there were no similarities at all, then one could discount creation.
Why? Isn't an all knowing and all powerful creator capable of creating millions of species that don't share any homologous structures?
In fact, why would such a creator need to reuse a single design? The only reason that humans reuse designs is because we are limited in knowledge, time, and resources. Without those limitations it would be just as easy to make each species from scratch as it would to reuse designs.
One also expects dissimilarities even amongst kinds, given that we know kinds adapt to their surroundings, yet always remain the same kind.
Still waiting for your definition of kind.
You can be sure they have confused fossils with different species when in reality most are more likely the same kind, just different appearances.
You have to define what a kind.
They talk as if they have genetically sampled these million year old fossils.
We have tested living species and found that they are our cousins.
They want things to occur in the past that we have never observed once,
False. We are pointing to the mechanisms of mutation, selection, and speciation, all of which have been observed and all of which can be tested.
They pick and choose what data to accept, and what to ignore. If the data contradicts their belief system it is the data that is in error, not their beliefs.
What beliefs, and what data?
[qutoe]It is a sad, sad, state that mainstream has let science fall into where only data that conforms to ones belief system is deemed valid. [/quote]
What data is being deemed invalid?
Science is observation and testing, and then fitting a theory to what is observed, not discarding data so that what is left fits the theory.
What data is being discarded?
How many years have they experimented with bacteria and virus's, yet they have never once evolved into more complex life, just stayed what they originally were.
You can't reverse 4 billion years worth of evolution in a few years in a lab. Bacteria are highly specialized at being single celled organisms.
From the Petri dish to the whale, kind after kind; always has been always will be.
You still have not defined kind.
When they start the ad homenim remarks, you know they are on the run, flopping like a fish out of the water with not one shred of evidence to back them up. When they attack the author, while ignoring the argument, it is from lack of any evidence to present in return.
When you start using religion as a term of derision to hide from the evidence, it is obvious that you have lost.
Don't let them fool you with their false religious beliefs.
Another example of you losing the debate.
