The human body is very complex but far from well designed. Up until recent advances in medical technology if most of your important organs failed you would die. We're pooly designed to remain upright and walking for decades (hence eventual knee, back, and foot problems later in life). We eat and breath through the same hole which leads to the choking deaths of thousands of people each year. There's a nerve that runs from our eye, down our neck, to our chest, then back up to our brains... all because a fish's eye and brain are essentially adjacent. The world is absolutely filled with plants, animals, bacteria, viruses, molds, and fungi that will kill us.

If you are implying that we are the product of intelligent design then that intelligence must have been moronic and inept.

You say, man. but you could just as easily say pigs. cats (in fact they have a second set of eyelids which is cool) or pretty much any mammal. There are also wonderfully complex species of reptiles as well but let's concentrate on mammals for now.
One clue to man's evolution is the appendix. a totally redundant and often dangerous remnant of our previous herbivore common ancestors. Now if you are a koala bear, then an appendix is an essential bit of kit. In fact, you better have a jumbo super size me one if all you eat is eucalyptus leaves. But for man, it is definitely not needed on the journey.
One good theory that explains evolution quite simply is Richard Dawkins "The selfish gene". He starts with a basic premise. "In the beginning was the gene and it has but 2 functions. To survive and reproduce". If you look at nature. You can see all the diverse and different ways that living things survive and reproduce. You can think of this as a natural arms race. Say for example the strawberry and the thorn bush. The former is tasty, easy to get at and leaves its seeds in you till you hopefully plop then on fertile ground. The latter has defences that can take the eye out of any mammal that even thinks about eating it. Both are successful, both survive and reproduce.
So how does that work with more complex species like mammals? Okay, let's take the eye as an example. One can understand how being simply light-sensitive or aware would give one species an advantage over another. If a mutation gave a multi-cellular organism some light-sensitive cells? It could tell if the sun was shining or not, day from night. The better they could do this, the bigger the advantage in the arms race. So the systems get more complex as every successful mutation gives an upgrade. (bear in mind for every success story they would have been millions of unsuccessful ones). Until we get to the very complex DNA code that makes our eyes.
Now here is a fascinating fact. A few years back, scientists spliced the eye part of a mouses DNA into a fly. The fly grew a third eye. It grew it on its back because it already had two eyes where they should be. But the really interesting thing is that it did not grow a mouses eye, it grew a fly's eye. That means that somewhere in the mouses DNA (and ours because our eye DNA is common) there is the blueprint to make a flys eye.
"Could we say he got it automatically? " is a very flippant and brief-phrase to cover billions of years of evolution. A very important theory which, however, once understood, unlocks the understanding of all biology.

why would you assume anyone created man, or anyone or anything else, to the extent of phrasing your question like that? have you not read any science books? google "evolution."

You are perhaps not as complex as you think anyway. Humans still have the basic mammal design, which has been around for million upon millions of years, and is little changed in us. And that is in turn, only a slight variation on the basic reptile/tetrapod design.

While if you think about, for example, your skeleton, you are basically just a bilateral tube, reinforced with bones in segments along the length, ( your ribs make this very clear,) while your pelvice, collar bone, and even jaw, are just highly modified ribs. In the end therefore, the basic pattern of a segmented worm, is still there and hardly changed.

From evolution over a great deal of time .... a lot more time than 6,000 years.

Why do our bodies have parts that aren't used? Why are our ears overly complex? Why do Manta Shrimp have better eyes than we do? Why is our food passage the same as our air passage. We couldn't choke to death if they were separate.

Ummmm, so do most all other vertebrates. Perhaps the Platypus God did it?!

Evolution, million of years of trial and error of nature.

Evolution

Whenever I encounter something that I do not understand I posit that it's the product of something else that I understand even less. It may not be intellectually rigorous but it gives me a false feeling of superiority.

As Terry Pratchett once wrote, we are bags of water.

Evolution does not have any regard for how complex or not its creations are, the only criterion is, does it work, and anything that works is kept. Though of course the more complex of organisms are more prone to going extinct, due to even slight changes in the environment. Which is why some of the longest lived, or at least longest in an unchanged state, are the simplest, there are species of single celled creatures which have been around practically unaltered since the earliest fossil records, while few complex organisms survive more than a geological era.

Amusingly, there is doubtful but interesting hypothesis about the saber tooth adaption, which illustrates this. Since there have been, many animals with the saber tooth form, cats, dogs, bears I think and even hoofed animals. Yet they all go extinct. The hypothesis goes that this happens because, having saber teeth is a very good adaption for feeding on large vegetable eating animals, which few predators are big enough or well armed enough to kill, so that saber toothed animals have a food source all to themselves. ( Not many things want to try an adult elephant.) And when once you have got your saber teeth and large strong body, then those with the biggest teeth and strongest bodies, thrive and prosper the most, in competition with their fellows, so that the bodies and the teeth get bigger and bigger.

The problem comes when there is a climate change, disease, or a disaster of some sort which causes the plant eaters population to plunge. Eventually the plant eaters populations may recover, from a few individuals who stagger out of isolated valleys. But the saber toothed predators can not live on a few scattered individuals in isolated valleys, they need huge populations spread widely. And because they are big, perhaps slow and have clumsy teeth, they can do nothing else, they can not live on or even catch mice or birds, such as a modern wolf would in hard times. So they go extinct.

And then, when thing settle down, evolution produces, because it is driven by inter-specific competition, another species of saber tooths. The process is mindless and remorseless. Competition says get better at your job, become ever better adapted, to out perform the fellow members of your own species. Until you are so highly adapted, you are a specialist, and you can do nothing else. Then a small rapid change is enough to tip you over the edge. And a few medium sized, none specialists, stagger of of caves in hidden valleys, diversify and it all starts over.

A human is no more complicated than a dog, cat, whale, orangutan, gorilla, etc. If some church-boy says that humans are different in that they have a soul, ask them to show the evidence.

No being consciously created the human being.

Evolution and the origin of life on earth may be counterintuitive. It is extremely unlikely that - at any given moment, in any given place - organic molecules floating in a primordial sea would spontaneously generate life. Yet such an event actually becomes quite likely to happen when given the virtually limitless opportunities in time and space for it to happen somewhere, at some time. A few extremely "lucky shots" become highly probable when billions of trillions of "guns" are firing every split second for a billion years or so.

Our intuition fails in the extreme scales of time and space involved in these events, the spontaneous generation of life and the evolution of diverse forms of life. Galaxies of molecules in each handful of seawater, reacting chemically in nanoseconds, under widely varying conditions over hundreds of millions of years - and the speciation of organisms over millions of generations - fall outside the range of human experience and intuition. Science gives us the finely tuned tools to "see" on these extreme scales.

Nothing is CREATED. That concept doesn't exist. Humans EVOLVED.

Huh?

Evolution.

For the moment, I will assume that you may be trying to clear away the last cobwebs of a creationist theology from which you have escaped. Even though being level 6 suggests otherwise. So I will recommend that you find some books on evolution such as Darwin's 'Origin of the Species' and have inquiring conversations with some of the people on this about which books to read about the sciences.
If, however, you are trying to push fruitloopery then you have come to the wrong site.

Definitely intelligent design

EVOLUTION is the REAL answer.
BTW, humans have 2 kidneys NOT 1 single kidney.
IF 1 kidney fails to operate then the second does its best to compensate, fish also have hearing organs (ears) though NOT the external ears that most terrestrial animals have.
The liver IS the ONLY organ in the Human body that can actually re-generate/repair itself AFTER suffering damage/s such as wounds, etc, BUT NOT from being abused by Alcohol consumption and the like.
It may appear to a complex structure BUT it is NOT, it IS merely a pound or two of minerals and salts and about a volume of 60+% water all held together in a very fragile bag of skin.
Humans are Primates that evolved from the earliest of Primate related ancestors who ALSO evolved from the earliest of forms of life such as single celled organisms, we ARE NO different to any other forms of life inhabiting this planet, we ARE all related, distantly as it may be, BUT still related none-the-less.

We could say SHE was created through something called EVOLUTION. Heard of it??

One of the wonders of nature. All that is true about the body.

Who ever did create they didn't do it all at once or with too much logic or absence of mistakes

Evolution.

That would be the lead to an Argument by Incredulity. With the answer right in front of you, how is it you CHOOSE to ignore it. How is choosing ignorance a search for truth?
