Hello, mate! from Australia.

>>This is what I don't think is true. I think DNA/RNA is product of evolution, not a starting point. The DNA, and sexual replication in general, is merely a strategy at replicating, and a pretty damned good one for practical and theoretical reasons. I think that replicators could be built much more primitavely than this scheme. You ask "how?"

The aboslute starting point was a molecule that replicates itself.

The prerequisites for such a thing are fundamental particles of nature and the fundamental forces of nature (electromagnetism, strong/weak nuclear forces, and gravitation).

You might ask, "How did those come to exist?" I think "God did it" is as good of an answer as any that we have at this point.
