Question from Wilson:
I am not an expert in biology just warning you, so feel free to enlighten me!
Correct me if I am wrong but evolutionists believe that life originated from a soup filled with amino acids or something along those lines. But there are a whole range of complex and simple microorganisms each with precise roles and functions almost like a program? And correct me again if I am wrong, now the cells function in a certain way due to a specific set of instructions in their DNA…how do you explain the exact precise instruction that each one of these different microorganisms have without there being an intelligent creator…finally I am also wondering how a bunch of amino acids decided to come together to make a microorganism and how that tiny cell decided itself that it needs to reproduce and how the heck microorganisms turn into a fish without a creator and if you’re gonna use time as an answer then what is the probability of such an event occurring for even a simple cell?
(Just as a lot of atheists find the idea of God absurd I find Evolution completely absurd)
Answer by SmartLX:
I’m not an expert in biology either, but a little research in response to things like this can teach you a lot, and I’ve been at it for a few years now. I’m still learning of course; while I write these answers I’ve usually got multiple other tabs open for reference material.
Before I go into details, the same logical problem applies here as to the last question I answered: the argument from ignorance. That’s not an insult, it’s the proper name for a specific fallacy where because you personally don’t know how something could happen, you assume it didn’t. Even if I had no answers for any of these, we would not be justified in jumping to the conclusion of a god until any other possibilities were not just dismissed but actually ruled out (or at the very least, actual probabilities were assigned to them).
I’ll try to address each of your points, but each of my points may not correspond to just one of yours or to the order of yours.
– There are multiple hypotheses about the origin of life from non-life (abiogenesis), and the “primordial soup” idea is one of the classic front-runners. Here’s a list of the current ones.
– Amino acids could occur naturally, as was demonstrated in the 50s, but a lot of different amino acids and other materials had to come together in just the right way to make the first simple proteins and genes. That’s a big factor reducing the probability that it would happen. However, there are three factors of a comparable scale which raised the probability: the sheer amount of material being constantly shoved against itself by natural forces, the huge number of different combinations that could have had the same effect, and finally the vast amount of time you mention – by current estimates, about one billion years from the formation of the Earth to the emergence of the first life form.
– The first life had DNA, or an equivalent like RNA, with one simple instruction: “Use the material around you to make another of yourself.” This was not an intelligent command, it was just something its physical makeup drove it to do, like a pinwheel spinning in the wind because of its shape. If it was in an environment full of the same material of which it was made, then this was straightforward: break evenly in two, then have each half absorb its own weight in raw material, then repeat. This is how microorganisms still do it today.
– Once life existed and was able to reproduce, it began to diversify. Slight imperfections in the self-copying process produced different offspring, and some of those differences were carried forward to the next generation. Whichever differences made it easier to survive and procreate, the creatures with those features tended to grow in number relative to the others. At some point a set of single-celled organisms joined together and shared their genetic material; the experiment was successful, and the first multicellular life came about. (Perhaps it had occurred before, but in the wrong conditions, and everything that tried it died.) At a certain point, small amounts of calcium became part of the essential material in the “body”, forming rigid structures; this helped with self-defense, and the viability of bones was established. Every tiny change that came about had to compete with other changes and come out on top, so every change that persisted had to have some benefit (or at least not be a hindrance), and thus a number of useful features began to accumulate. It’s been so long now that living things and their genes seem to be made of nothing but useful features, though some superseded components (like the appendix) have yet to be eliminated entirely.
I recommend reading at least a couple of books on evolution, just so you can know what the theory actually says before deciding whether it’s so unlikely. Your Inner Fish by Neil Shubin is about to be accompanied by a TV show. Richard Dawkins’ early book The Blind Watchmaker is a great primer, and has little or none of his recent anti-religious material that puts believers off him. Just don’t restrict yourself only to books on evolution by creationists and/or Intelligent Design proponents, because all they do is claim that various things are impossible when at worst we just don’t know how they happen – and sometimes when we actually do know.
