Point #2: 20 billion years is not enough time for the observed complexity to be produced at known rates of change.
Response: We observe minor changes taking place in species during periods of weeks, months and years. Evolution on some scale is thus an observable fact. You argue that the rates are not fast enough. How fast do they need to be? It is accepted that several mutations are present in each individual born.
What changes are you speaking of? Mutations resulting in loss of information or added information. One specie turning into a whole new specie?.
