To get a better idea of how life began you need to familiarize yourself with amino acids and proteins. These are the building blocks of life. Even things that technically aren’t “alive” (although that’s up for debate) like virus are composed of amino acids and proteins.
I think it will make it easier to understand if instead of going from gasses to humans, you focus on the sequence of events more, down to the point where amino acids become proteins. We know how amino acids form. We know how proteins create life. What we don’t know is how exactly the first proteins formed from amino acids.
Once life begins its pretty straightforward to understand natural selection. Before life begins its just chemistry. Its that very brief, nebulous point between the two time periods we don’t understand.
