Hadriel almost everything you have written is so muddled it is abundantly clear you do not have the slightest clue about origin of life science.
in very short we're talking about RNA and its condons translating to DNA
I assume you mean codons. RNA in early replicators did not code for DNA. Two simple chemical changes happened - really simple ones - that changed some RNA into DNA. Chemically they are really similar.
LUCA is not contrary to origin of life
I don't know what you mean by that. LUCA is the earliest ancestor of all life. It was already a complex cell that became the ancestor of bacteria, archaea and 2 billion years later eukaryotes. A huge amount of things happened before LUCA existed.
If you can't explain that process you cannot say with anything definitive as to that early bacteria like RNA started chaining and ultimate became DNA.
What do you mean by "bacteria like RNA"? When RNA first formed it was a long time prior to anything we could call bacteria.
Why did you not just say that scientists don't know for sure how chemistry became biology and we would all agree with you and have a productive conversation about the fantastic progress that has been made in recent years?
Instead you spend pages posting self-contradictory statements and using words and phrases that make no sense.
A huge amount is known about the origin of RNA, DNA, proteins, respiration, metabolism and many, many more features of the first cell. I am not going to spend hours describing it to you when you clearly have no interest in the answers and not even a basic understanding of the science. I will recommend a reading list if you like.
