RNA World is a religious belief.
No religion endorse it.
Concensus and faith without evidence.
None that John Larkin can understand. In fact all life depends on a couple of RNA based enzymes, and they probably have been there from the start. Some viruses are RNA only. DNA offers a more stable genome, but there aren't any DNA based enzymes. John Larkin is arguing from ignorance, and he's got a lot of ignorance to draw on.
Just watched some news story where a sort of computer robot was teaching kids...
Again, an other science program today on TV about planets: all sort of basic chemistry was found
on some moons and asteroids.
Sure. Chemicals are not life, as a junk box full of parts is not a
working electronic instrument.
They did a testing in the lab and made RNA from just basic chemicals added some heat cycling and dry soak cycle
like you will find on planets (sun, tides):

We are an astoundingly complex structure that uses chemicals and
quantum mechanics. At least I am.
Sadly. John Larkin isn't all that complicated. Push the right button and you get the same half-baked response every time.
A better education might have provided a greater variety of responses, but he still hasn't got a patent of his own.
