OK, lets stop here for a moment.
Up to the point where the Replicator was formed, there could not have been any selection. Please describe this Replicator.
What was it made of?
RNA?

To be honest, I am not sure. Some precursor of RNA perhaps. :ask: Chemicals self-select themselves all the time. Some abiotic reactions are auto-catalytic. In titration, suddenly the buffer solution can no longer hold back the change, and a tipping point is arrived at. The colour changes. My point is that there are all sorts of selectors and filters in nature that do not need life to happen.


Perhaps not.
However, such Replicators aren't found anywhere in nature - outside of living systems.
We don't come across molecules which copy themselves, and evolve to more complex molecules - unless they were originally based on the chemistry of life.
Chemistry and Time alone don't seem to do it.
...or do you have evidence that they do?
