It seems that our DNA code is fantastically complicated, more so than originally conceived.
DNA aside, life is more complex that envisioned by Darwin. Darwin believed in protoplasm, akin to some living jelly. We now know that a living cell is very complex. It has been said that a cell is more complex than a nuclear submarine, advanced as man's most complex created entity.
Given all this complexity, it seems there was not enough time for life to arise and evolve through mutation and natural selection.
I suspect one reason some people advance the idea that there is an infinite number of universes is to give evolution a chance. (To paraphrase John Lennon, “All I am saying is give evolution a chance”).
Nature's Destiny, by Michael Denton, suggest that evolution, and presumably man, was the plan all along.
One author made the claim that simple bacteria have more DNA than any of us. (I've found this hard to confirm or disconfirm.) The hint is that simple bacteria had it all from the start. DNA for a horse, a shark, a dinosaur, a tree, a human. Then natural selection can down-select to fill an evolutionary niche..
I suspect that we will never be able to establish a natural or supernatural origin completely beyond all doubt. My theological understanding is that the universe was created so that you could choose. There will always be mixed evidence. Most people will emphasize some evidence, and de-emphasize other evidence, to suit their desired outcome..
Thank you for the great post.
