Don’t know. They just showed that Uracil could be produced in conditions present in space. Maybe they are working at it.

Finding the answer to one small step can take a long time.
I had to change about 10 DNA bases of a gene to get it to be expressed in the organism I wanted it to be expressed in -the organism had a quirk in it’s genetic code. A certain amino acid was coded by a different codon than normal. It took two of us about three weeks to do it and verify the sequence we wanted was correct. Add that to deciding what promoter (switch) to use to turn it on and what DNA vector was needed to introduce it into the organism. Took about 3-4 months.

All that deliberate work by more than one researcher.

And we're supposed to believe that lightning bolts in the *right* kind of atmosphere under uncontrolled conditions with impure solutions of reactants was supposed to lead to the formation of life of the complexity of that exhibited by even single celled organisms?
