    It's not that simple, Tonio, what took millions of years to emerge and evolve when the conditions were right, with all the means and mechanisms still not fully understood cannot be simply recreated in the laboratory.

    DBT9,
    That is a fallacy.
    You can make diamonds in a laboratory. It does not take millions of years .
    You can also make RNA. in the laboratory.

    I wonder if you actually read the articles you put up. Here is the link to another one and some extracts.

    RNA world (article) | Natural selection | Khan Academy

    The RNA world hypothesis suggests that life on Earth began with a simple RNA molecule that could copy itself without help from other molecules.

    All living things reproduce. They copy their genetic information and pass it onto their offspring. And for RNAs to start life, they needed to reproduce too. This is why scientists think that the RNA world took off when an RNA emerged that could make copies of itself.

    DBT9,
    Machines can synthesize billions of DNA sequences, and use them to construct the corresponding RNA molecules.
    There is no problem with building RNA molecules. Your problem is making one that can make copies of itself.

    We have a work in progress in understanding how life emerged and evolves. That life evolves is proven.

    Actually DBT9, the RNA world has stalled.
    First find an RNA molecule that has emerged and can self replicate before you try to prove it can evolve.
    Remember,

    The RNA world hypothesis suggests that life on Earth began with a simple RNA molecule that could copy itself without help from other molecules.

    Even cheating using DNA sequences they can't produce self-copying RNA.
