Evos typically say that's not formally a part of evolution theory...so therefore that's not a problem.
Its only not part of evlolution when one seeks its credentials. When applied in support of materialism its routinely presued as proven so thouroughly that one must be an anti science dunce to doubt it.

Well... not necessarily a problem for basic evolution theory (descent with modifications plus natural selection), but a far more complex difficult problem.
A basic question is: when & how does interesting organic chemistry first become the simplest possible form of life?
Current hypotheses & models are, well, light-years beyond the 1952 MillerUrey experiments, and while fascinating cannot be called confirmed theories.
So far, any abiogenic origin ideas can still be falsified and panspermia (non-Earth origins) cannot be ruled out.
