Thank you for taking the time to post this response
and to be honest, I don't understand everything you said
So the big question I have is, How does the single-celled (life) start?
I guess scientists don't know yet right?
and are you saying that there are no biologists who believe in God?
That's fair. It's good to ask questions. There are no biologists who disbelieve in evolution. I personally know a few biology professors and they understand that the process that started life is definitely a natural process that we will eventually understand. When scientists say they don't know how life started it's because they are extremely exact and meticulous. They need to have proven theories for every single step. Right now we know the building blocks of life like amino acids, proteins and such occur naturally. They know self replicating chemicals occur and can form more advanced structures along the chain like nucleopeptides. We do not yet understand how a simple RNA was formed. But the basics are there, it's just a matter of time.
Some biologists do believe in some God they just assume it created reality or nature and the big bang and life are natural parts of things that will happen in nature. They generally don't try to insert God in places where science cannot answer because that has been done for centuries and always turns out wrong.
Overall scientists tend to believe in a theism less than the general public. I have a family member, a biology professor who is Catholic and attends church weekly. But he doesn't believe any of it. It's just tradition and structure and a way to have some type of spirituality.
So the big question I have is, How does the single-celled (life) start?
More complex cells - eukaryotes - formed from simple cells (no nucleus) prokaryotic cells, the simple cells evolved for around 1.5 billion years so they had a long time. Simple cells have proteins, membranes, probably had a simple RNA and a few other things that occur naturally. How they got together is not my area. There are many pieces to the puzzle that are known and theories about other things that we are not sure about.
It's a bit of a fallacy to think there is one magic point where we need a God. We can demonstrate simple cells evolve into complex cells or RNA may become DNA and millions of processes that happen in the formation of life. So why would there be one step that is too much to fathom? For example this paper proposes nucleopeptide reciprocal replicators could be the key. Nucleopeptides have been shown to form naturally. So now we just need one that replicates. Replication is also something that happens naturally.
Even the simplest organisms are too complex to have spontaneously arisen fully formed, yet precursors to first life must have emerged ab initio from their environment. A watershed event was the appearance of the first entity capable of evolution: the Initial Darwinian Ancestor. Here, we suggest that nucleopeptide reciprocal replicators could have carried out this important role and contend that this is the simplest way to explain extant replication systems in a mathematically consistent way. We propose short nucleic acid templates on which amino-acylated adapters assembled. Spatial localization drives peptide ligation from activated precursors to generate phosphodiester-bond-catalytic peptides. Comprising autocatalytic protein and nucleic acid sequences, this dynamical system links and unifies several previous hypotheses and provides a plausible model for the emergence of DNA and the operational code.
Reciprocal Nucleopeptides as the Ancestral Darwinian Self-Replicator
"The spontaneous formation of organic molecules was first demonstrated experimentally in the 1950s, when Stanley Miller (then a graduate student) showed that the discharge of electric sparks into a mixture of H2, CH4, and NH3, in the presence of water, led to the formation of a variety of organic molecules, including several amino acids (
Figure 1.2). Although Miller's experiments did not precisely reproduce the conditions of primitive Earth, they clearly demonstrated the plausibility of the spontaneous synthesis of organic molecules, providing the basic materials from which the first living organisms arose."
