The Theory of Evolution is simple and easy to understand. It's also convenient to cling to if you don't want to be bothered with the idea of an omnipotent arbiter of good and evil and the associated immutable standards of morality. Those of you that need a worldview adjusted to your existential philosophy and associated deviant behaviors won't care about the following questions. Those of you that think evolution actually makes more sense than intelligent design might want to read on. I once thought evolution made more sense but then I learned something about organic science.
If I remember correctly Darwin's Book is called "The Origin of Species." Here are some hard questions for Evolutionists about the Origin of Species:
Was the first single cell organism an animal or plant?
If it was an animal what did it eat? Animals only eat organic material.
If it was a plant, it would have needed to synthesize it's own food. It would need to bio-originate with a fully functioning photosynthesis capability. Probabability? Zero Point Zero to 20 decimal places.
But for the purpose of exploration, lets just allow that the immaculate bio-origination with a fully functioning photosynthesis actually happened. We now have a living single cell creature. Let's assume it has an extraordinary life span for a single cell creature, say... 200 million years. At the end of 200 million years, how many single cell creatures would there be?
Answer: One. This single cell creature would not be able to reproduce unless it had what we call DNA. DNA strings are the most complex molecular structures known to man. And it would have to bio-originate as one of these critters that splits itself in half to reproduce. Every living creature has DNA. Even viruses. Viruses steal the cells of other creatures to reproduce their DNA.
So this immaculate bio-genesis would also need to include the spontaneous accidental construction of DNA and the instinct/coding to cause reproduction. Probability? Add some more zeros...a lot more zeros.
Maybe more than one of these critters spontaneously bio-genesized. If there were two of them, they'd need to have recombinant DNA to reproduce. They'd also need to be in the same place at the same time and they'd need to have the instinct to reproduce. Add some more zeroes.
But just for the point of argument, lets say it happened just like that. Shazaaam! Right there in the midst of some primordial sea, a spontaneous, bio-genesis of a single-cell plant with fully functional photosythesis, DNA and reproductive instinct/coding. It starts reproducing. It makes more and more of itself. It even evolves into multi-celled plants. They multiply like roaches. They consume carbon dioxide and water and turn it into oxygen. There are no predators. What happens when a life form has no predators? It reproduces until it over tasks the food supply. Plants everywhere. The whole planet is green.
It's likely that the plants would consume all the carbon dioxide until they choked themselves to a level of balance. There are none of the little microbes and fungi that compost plants down into rich topsoil, the only reduction would be solar decay and combustion started by lightning, volcano or meteor. Maybe that would happen often enough to keep a supply of CO2 to keep the plants growing.
Suddenly at some point, a plant mutates and stops consuming carbon dioxide and begins to burn oxigen and feed on plants. Or suddenly a plant gives birth to an animal. I like science fiction, and that one sounds like science fiction to me. A plant giving birth to an animal. What are the odds on that one? Add some more zeroes.
These are just the questions that come off the top of my head. We need to remember that Chucky Darwin didn't know about DNA. He didn't have electron microscopes or a reasonable understanding of photosynthesis. In fact, organic chemistry was in the dark ages.
But there's another direction to start from: What if there was an original lifeform that didn't need photosynthesis and DNA. It needed nothing but sunlight, rocks to eat and water to absorb. It can reproduce itself and make it's own food. Sounds like a pretty hardy critter. Can live in the most austere of environments. Actually, it sounds like a weed. OK, cool... where is it now? It was prolific then but none of them survived. It could live then but not now. Now there's too many sources of nutrients to eat. But eventually it developed photosynthesis even though it didn't need it and it developed DNA even though it didn't need it either. Cool - it just invents two complex chemical processes for no reason. and then after a while it get tired of that and changes itself into an animal. Sounds pretty far-fetched to me.
Mr Darwin has sold you a bridge that goes most of the way from the present to the origin of life and then ends abruptly just before the other side. You can believe in it if you want. But it will require you abandon hard science and make a leap of faith. It requires an energetic leap of faith.
The requirement for a leap of faith means the theory of evolution becomes a religion when examined under 21st Century Science. Intelligent Design answers all these questions while Mr. Darwin stands speechless.
