The reproduction of DNA and RNA is not the issue here. DNA and RNA is essential for life to exist in the first place. So if the evolution theory starts from the basis of DNA and RNA existing already, we cannot say that evolution is how life started, because DNA and RNA has to be present at the same time and work together to sustain life.
Now, you're catching on! That's it exactly. We can't say that evolution is how life started. That's not what the theory is about. The theory of evolution starts after life appeared, and makes no claim about how it did start, only what happened afterwards.
