Because I would never go to an auto mechanic to fix my plumbing.
From you specifically, no, as I have read the studies and have been exposed to the evidence and by people with actual backgrounds in the relevant fields of science that lend evidence to support the theory of evolution.
I actually do have a footing towards having credentials, and am close to having more than just a footing. Things such as pro-social behaviors in social animals, similarities in behaviors between humans and chimpanzees, and even non-verbal signals found throughout the animal kingdom (such as an animal, or even reptile or fish, puffing up and making themselves appear larger to look more threatening and intimidating) bring up observations and questions that are answered and predicted by the theory of evolution.
There is no such thing as an "evolution believer." No more than there is a "believer in mental illness" or a "germ believer" or "gravity believer."
You haven't been doing this.
Dawkin's own personal opinions reflect his own personal opinions, not the findings or functionings of science.
That is not how science works. There is a "side" for a flat Earth, but the Earth is not flat and will not flatten itself because people believe it is, nor will the facts and evidence ever support such a position. Science works by making predictions, recording systematic observations, replicating experiments and results (or finding different results), and falsifiability of a hypothesis and theory is a must. Evolution can be proven wrong, but what we learn only adds to support evolution. About the only way evolution is ever going to be proven wrong is if we find fossils that are very geochronologically out of place and we discover a mechanism beyond random mutations that drive DNA replication.
