How the origin of life through the understanding of evolution is factual if it's contradicts the knowledge of cells?

Charles Darwin's theory of evolution is the widespread belief that all life is related and has descended from a common ancestor and that birds, fruits, fish and reptiles are all related. It is said that complex creatures evolve from more simplistic ancestors naturally over time. Many people believe it is a fact, but the theory of evolution is flawed and that is why it is only a theory. How can evolution be true if it contradicts the knowledge of scientific things we already understand?

The beginning of life through the theory of evolution came along by chance. Science shows that in order for a cell to survive and reproduce, it must have DNA, RNA and proteins, which are complex molecules. What is the probability that DNA, RNA and protein formed by chance? RNA is needed to produce proteins but at the same time proteins are needed in the production of RNA transcription. One couldn’t exist without the other. What are the odds of both RNA and protein appear by probability at the same time and place?

The way cells work and are made are too complicated to be made by chance through evolution. The probability for every cell to know it’s job in the body and work in harmony for it to properly run the body is nearly close to zero percent.

Marshall Brain, author of the article “How Evolution Works” said that the first living cells had to possess “A cell wall, the ability to grow, the ability to process other molecules floating outside the cell as food to create energy and the ability to split itself to reproduce.” How did a cell know how to do these things in the beginning of evolution? It takes time for a trait to be pass on but the chance of all these traits to already be given to the first form of life is low. Even though some things have been proven factual in the theory of evolution such as natural selection, the origin of life from the theory of evolution is hard to believe.
