great! so going with that idea, in my view, the first thing that can be reasonably called "a human", for any of us, is that first single cell, the fertilized ovum.
God forms that first single cell that we call 'adam' out of dust, and forms him 'ready to go', ready to start dividing, taking in nourishment.
Please cite one observed example of a single cell suddenly appearing, nourished by soil that provides the bewildering supply of finished amino acids and thousands of other organic compounds necessary at once, in concert, to sustai nthat original single cell even one minute!
Why bother with a universe necessarily full of special miracles just to invent DNA when our Supreme God can by his words create one living being along with all necessary conduits of life, sustaining its growth, and matching the very image and likeness of his Creator God? The alternative was to create a huge laboratory filling the entire universe, full of imps, each concocting a particular chemical, others arranging the exactly right chemical reactions between all of those products, with the aim of making a living man.
Well, nothing in nature hints of such a process. Man was made a man all in one day, fully functional with no announced faults whatsoever.
Rather, the word of God plainly states that God fashioned Adam from dust, like a potter forms a vase. He then breathed life into the man, and he became a living vase pleasing to God.
Looking at the physiology of man, that Adam could not have escaped rot past a few minutes of formation without given full functionality that same hour. That lifeless "vase" could never have lived to be a man without a fully functional circulatory system, endocrine, resperatory, skeletal, muscular, etc set of perfectly cooperating systems, all in the same "hour", actually within about 2 minutes of our time. Within 4 minutes he would have remained brain dead.
Quit letting Satan celebrate his partying over human stupidity! God did it the only way possible, yet naturally sustainable by reproduction of Adam's "kind".
His flesh heart couldn't have hung around thousands of years reproducing more hearts, eventually figuring out a way to get oxygen into the heart muscles, enough to begin forming a stomach and intestines to process food energy.
But wait. That would require a mouth and teeth to take food in. But wait. That would have required that heart to devise lungs to absorb oxygen.
But wait, none of that would occur without first the heart muscle developing a brain and senses like sight, smell, taste, to search for and take in food.
The point is that little ovule wouldn't have had those testes to form in until late in the evolutionary process, so from the date of the heart formation, all else would have never happened, but would have perished, and that original heart would have dried up into a slug a day or two after existing.
The way God says it happened is great science. The complete human body was made in a single day in the personal attendance of Creator God who knew all the required steps, and possessed the necessary skills to coordinate all of them perfectly. He didn't even let the human eye suffer loss from lack of systemic coordination! It's the only sensible explanation, because that is the truth.
