This is a transferral of my conversation with Anonymous over at www.atheistethicist.blogspot.com, since I've clogged up enough of Mr. Fyfe's comment thread space already.
Anon's last comment:
The theory of evolution includes the big bang it is not just from when life began. If it includes the big bang then it includes cosmic evolution. If your idea of the theory of evolution starts when life has appeared on the earth then why do you have a problem with creation.
Creationist rhetoricians, I think, like to group theories like evolution with others like abiogenesis and the big bang to make a "stronger" case of - "Oh look at how insurmountable the odds must have been for x, y and z!!!."
UC Berkeley has a helpful introductory site to the theory.
There, it defines evolution thus:
Biological evolution, simply put, is descent with modification. This definition encompasses small-scale evolution (changes in gene frequency in a population from one generation to the next) and large-scale evolution (the descent of different species from a common ancestor over many generations). Evolution helps us to understand the history of life. *The theory of evolution does not demand or imply the Big Bang theory, nor does it demand or imply that abiogenesis occurred. Notably, among educated scientists, approximately 0.14% (an extremely small number) do not believe the theory of evolution describes reality.** Yet polls suggest - from what I've heard - that at least 50% of scientists call themselves Christian or theistic. I may be wrong here...
However it is certainly not the case that a belief in evolution is inconsistent with a belief in a God.
To answer the second part of your question:
I'm an atheist. Basically every reason I have for being such doubles as "a problem I have with creation."
