I want to quote a quote Richard Dawkins makes in his book The Greatest Show on Earth (Video). It is about a lady who didn't believe in evolution:
… He was asked by a lady:
Even given the billions of years that you say were available for evolution, I simply can not believe it is possible to go from a single cell to a complicated human body.
But madam you did it yourself, and it only took you nine months.
Btw. and I can not believe that the Kindle Edition is more expensive then the Paperback version.
Homer Simpsons shows how it is possible.
