Look up the Haber process, the industrial process for making ammonia, made up of 4 atoms- 1 nitrogen and 3 hydrogen. Appreciate the effort that goes in for chemists to get the gases (reactants) to react.
Now consider human DNA which contains 23 chromosomes, containing about 8.5 billion atoms per chromosome. Humans will never be able to come anywhere close to making this from scratch. Everything in the physical world is made up of chemicals. They do not bump into each other haphazardly in nature and build up one by one into mega molecules like dna, even over billions of years. Think of atoms like Lego, they need a person to put them together. In reality chemicals are not like Lego, needing complex conditions each step to build simple molecules like the Haber process, each step.
No human knows, or will be able to know where consciousness comes from while breathing, that’s common sense. The incredulous say it’s an extension from monkeys.
I hope this helps you to understand God the Creator is the very logical answer, no incredulity no ignorance.
