There are 3 billion base pairs in the human genom(a cell) and around 30-40 trillion cells in a human each specialized for a specific function.
There are approximately 86 billions of neurons in the brain.
The eye has a cornea, iris, pupil, lens, retina, optical nerve, macula, fovea, Aqueous Humor, Vitreous Humor, Ciliary Muscles, sclera, Choroid and Conjunctiva to name a few. The eye can distinguish between 10 million colours.
The human gut is home to trillions of microorganisms, collectively known as the gut microbiome.
These are just a few incredible facts about the human body there are hundreds more.
This doesn't even touch on the origins of the first cell, first DNA, first multi cell etc etc
How can you expect anybody to believe that it was random mutations that ultimately created all of this, the complexity is ridiculous and there's no way all these complex organisms could have evolved to work together in harmony as they do?
The idea of random principles driving all this order is ridiculous. For example, randomly rearrange the words in a paragraph or the parts in your car and see if you can improve it or add new improved ordered meaning. Order requires an ordering principle or two, such as a knowledge of grammar or knowledge of car making and car function. If you know these things, you have a shot to improve and not do damage via change. There more things thing that can go wrong then right with a random approach. One genetic defect can be life threatening.
The best two ordering principles I could find for life are water and the 2nd law. The second law states that the entropy of the universe; complexity, has to increase. We have a science based law and potential for change and complexity increase. Science has very few laws but theories are a dime a dozen, so why not use a law for credibility? While water and oil or water and the organics of life, do not mix, but rather tend to separate when they interact; compartments and organelles. If I mixed water and oil and try to combine them into a solution, once I stop shaking, they will mutually separate, imposing repeatable order. When proteins are manufactured by a cell, the water packs and folds them into repeatable packages; water-oil effect. This is not randomness achieving the same order each time. We need a set of natural ordering potentials and not random hocus pocus, since repeatable order is observed in life. How can mother cells make two daughter cells that both become ordered using random?
Water is very effective at ordering life because water is the majority component of life with 50 times as many water molecules as all the organics combined. Each water molecule can form up to four hydrogen bonds, with hydrogen bonds the strongest secondary bonding forces in life. Life is fluid and hydrogen bonding is king of these fluid structures. Water comes first and organics needs to evolve to maximize the water, with the water pushing for change via its secondary bonding dominance. When water and oil separate, the water is imposing this, so it can maximize its own hydrogen bonding matrix. The oil has to follow suit since it is being displaced by water. Water is what makes the DNA form a double helix to shield the bulk water from the organic bases and sugars.
Water is very stable and the product of combustion or fire. Water does not change over time, even over billions of years. The system of water and organics, when subjected to the 2nd law; change and complexity, has to focus change on the organics in light of the dominance of water. The net result is water stays the same while the organic of life do all the changing to accommodate the needs of water. Life has one stable and stationary bookend and one moving bookend. The stable bookend imposes order on all change.
The DNA will not work without water. There is a double helix of water inside the major and minor grooves of the DNA double helix. The base pairs of DNA have twice as many hydrogen bonding sites for water, then are needed by the base pairs, to pair up. Water is twice as valuable to the hydrogen bonding structure and function of the DNA. The DNA is not bioactive without this water. The amount of hydrated water will define the conformation of the DNA with B-DNA the most common and having the most hydration.
In most textbooks, this water is not shown. Do a Google search and try to find it! This omission of the water; dominant principle, results in the illusion of needing a random placeholder to explain the ordering nature of water upon the evolving DNA oil. Once you add the water to the analysis it is not random at all. The problem is science malpractice, due to using the same math for science that is used by gambling casinos, politics and marketing. Random is more like a campaign slogan oracle than rational science.
In my experience, if one does not fully understand how things work it appears more random than it is. The black box approach is a tell since the black box means you start in the dark of ignorance, and apply a math method or oracle to help you see something. That is middle ages science before the age of reason. My guess is science was hijacked by politics and the free market, who imposed their math on science, to dumb it down and control it, for the needs of an assembly line workforce. Random is a useful applied science tool, being used for pure science, and it does not belong there. The result is manufactured theory and not pure rational theory. This is OK in a factory or casino, where manmade it the gaol, but not if the goal is to explain the natural order in the natural world.
