Again, we already agree that the origin of these natural cellular processes, and the origin of cells themselves is problematic from a natural/materialistic view. However, once they exist....
So regardless of how such cellular processes came to be they're here now and cause evolutionary changes in genomes and organisms without the need for divine intervention. And these processes include the ability to do *natural genetic engineering* that results in random genetic changes in genomes and random gene shuffling and random transfers of different genes and mobile genetic elements within genomes, and between genomes, and between organisms in a controlled way that allows for natural variation and natural genetic "experiments" without lethal effects.
That is to say these random changes are not *accidents* but normal cellular processes that generate new genetic variation and evolutionary changes in genomes and organisms. In the same way that "crossing over" is a normal, natural process during cell division that results in new genetic variation and new *random* genetic combinations that are not *accidents* but a result of normal functioning of cells (*no divine intervention needed).
(Recombinant random genetic shuffling due to crossing-over)

*If you want to say an Intelligent Designer originally put this all together and created cells with the ability to naturally evolve, then you could say that if you want







Well however you want to qualify it, these are still natural, cellular processes. And however they got there in the first place and however cells first originated, cells have them now and many evolutionary changes (MAJOR evolutionary changes in genomes and organisms) occur by way of these empirically documented and well-studied *natural* processes of symbiogenesis, horizontal gene transfer, hybrid speciation, and natural genetic engineering (via mobile DNA elements) without the need for divine intervention by an intelligent designer.
Are you suggesting it’s evolution no matter what? If it was due to a design than within the code every adaptive process was coded to occur and not only that it would require the ability to evolve in new species over and over throughout time allowing each new life the same properties. The other possibility chance and necessity which has no creative power only destructive.
When you refer to “natural” processes as if you are explaining what is going on, you are leaving out all the mechanisms that do the work without saying how did this come into being? Instructions don’t just happen without a cause capable of creating them.
