IMO all steps were forced by the sun's heat/uv cycle.

What didn't survive burned up.

What did survived and survived in variant forms - the more successful
variants were able to reproduce, use the energy,
have cells, etc.
Life is not an emerged magic, or fluke creation,
or 'goal oriented to get to us' - its a reaction to an environmental sun cycle.
Take the sun out and see how far you get in any
origin scenario.
(I have numerous posts here to explain these ideas)
Good luck,
