So many scientists are so blinded by their refusal of the possibility that God created the world that they do not see how ridiculous their theories are.
So, RNA couldn't have converted into DNA, so they had to have started evolving together. The whole point behind the original RNA to DNA theory was that RNA is less complicated and therefore more plausible to have spontaneously self-assembled. Now we are told that even the more complicated DNA came together automatically.
To quote the professor: “Why not think of RNA and DNA rising together, rather than trying to convert RNA to DNA by means of some fantastic chemistry at a prebiotic stage?”
Yet we are to believe that DNA and RNA could spontaneously self-assemble by some fantastic chemistry.
I'm sorry, but biogenesis is simply impractical and using probability completely impossible.
