Forgive me, but "I've decided" is probably more accurate than "I've concluded" and it is a bit..... Naughty.... To discuss chemistry and science and then in the end make a 'conclusion' based on opinion.
That is not what science does.
Also, molecular forces explain the formation of these processes, simple physics explains why these naturally form and I'm not sure what your issue is?
Atoms, molecules develop charges and that dictates free movement of particles and molecules. For example, space is full of sugar because hydrogen, carbon and oxygen is in abundance (having formed in stars) and naturally join together due to the difference in charge, forming molecules. Note DNA has a 'sugar' backbone. Your molecule is H and C and O .... formation of such molecules is no mystery and certainly doesn't require 'guidance'.
Lastly, it is a weak argument to follow science and it's 100+ years only ,of explanation and new understanding (even less in years with modern physics and chemistry) then at the point where we are at, awaiting an understanding, say.... "Aha God does it!" That is illogical and reduces God to the latest thing to be understood and when it is understood, makes him/her/it simply more impotent and invisible.
Humans once concluded thunder was god pissed off...... rainbows were God promising to never be pissed off again.... 🙄........
Scientists do not see a gap in knowledge and then without evidence insert a complex, all powerful and jealous deity as the likely explanation.
That is not science. Not logical. Not intelligent. Not helpful. Not an answer. Not evidence of said assumed deity.
The dark ages were called dark for a reason....
