There is no scientific evidence for RNA world. RNA has never been seen evolving into DNA.

RNA is transcribed into DNA in every human being every day. RNA hybridizes with DNA, and there is complete compatibility between RNA nucleotides and DNA nucleotides.

No naturally occurring RNA molecules have been found that direct the replication of other RNA molecules.

Wrong, I'm afraid. Very, very wrong.

Performing your original search, RNA-dependent RNA polymerase, in PubMed will retrieve 2020 citations.

Well, no it would be a force unknown implementing the design. Sort of like how RNA would switch roles with DNA.

Happens in every RNA virus.

Even without hydrolysis, RNA breaks down from background radiation.

So does DNA, at essentially the same rate. Photochemically, there's little difference. The big difference between RNA and DNA is the availability of 2',3' cyclic intermediates for RNA hydrolysis

Anyway, the lack of enzymes is also a stumbling block. Without protein enzymes, researchers have not been able to produce a duplicate of a RNA template.

This has not been a good day for you.

Show me where an RNA molecule apart from a DNA molecule adds a DNA molecule.

RNA polymerase is a protein. We are discussing RNA World where the idea is that RNA doesn't use proteins to replicate itself.

Even without hydrolysis, RNA breaks down from background radiation. So does DNA, at essentially the same rate.

And we're not talking about abiogenesis in a DNA world.

Anyway, the lack of enzymes is also a stumbling block. Without protein enzymes, researchers have not been able to produce a duplicate of a RNA template. . . This has not been a good day for you.

Have you been reading your links?

"Full non-enzymatic replication of RNA from monomers has never been demonstrated. To achieve this remains the holy grail of this field."
