For me it is about that catalyst, until that is solved both are nothing more than theory.
We had a very long conversation about that and despite numerous requests for you to define what you mean we are no better informed..
I came to the conclusion that you don't understand your own "question".
I told you above about three prominent scientists who have provided a compelling hypothesis about the origin of DNA and offered to tell you a lot more about it.
There are just two tiny chemical differences between RNA and DNA. Both of them would easily have occurred spontaneously in the alkaline vents that were the nursery of life. I will explain more if you are interested.
You really don't want an answer do you?
