You can puff up the theory of evolution to be as factual a theory as much as you like, you can call it things like infallible and proven, tested, etc. But in the end it boils down to this:
People think (not know for certain) it's correct, based on what they've 'done' 'seen' and 'heard', via other people.
It can't be proven like the theory of gravity can, because no one has ever witnessed a creature evolve. Humans within recorded history have never evolved.
Okay, first of all, I know your post is two days old, but I've read most of the thread a bit late, so. I don't intend to flame or start an argument, I just found your post to be worthy of a reply (it reminded me of my way of thinking when I was younger and not a college student).
Now that's out of the way, I'd like to say that evolution does not necessarily mean transformation from one life form into another or whatever people believe evolution means these days. I know Wikipedia is not the peak of human knowledge, but check out Wiki's definition of evolution. It's only one sentence: "Evolution (or more specifically biological or organic evolution) is the change over time in one or more inherited traits found in populations of individuals." (with this source: ^ a b c d Futuyma, Douglas J. (2005). Evolution. Sunderland, Massachusetts: Sinauer Associates, Inc.). Within recorded history, humans did not develop wings or morphed into astral beings (and probably never will), but we did evolve. First and foremost, our lifespan increased. Second, we grew to be taller on average. If there's this included in the definition ("Inherited traits are distinguishing characteristics, for example anatomical, biochemical or
behavioural, that are passed on from one generation to the next." - the sentence right after the first one from Wiki), do I even need to go on on how our behaviour evolved during recorded history? And there's the simple things, not exclusive solely to recorded history; humans with darker skin? It's not for aesthetics, it serves a purpose and it
evolved to protect humans from the dangerous sun rays. Black people can sunbathe without sunscreen while I'll get major skin burns if I do that.
We can also completely ignore the humans. There are other life forms that we can observe and see their evolution. Ever saw more than one dog breed? Evolution (artificial, selected evolution, but evolution). We breed them as we like it. How do you think we even got dogs in the first place? By selectively breeding wolves and taming them to become obedient and less aggressive to humans. Dogs did not just magically appear because we needed them; it was a live and long-lasting process of selectively taming and then breeding favourable traits, while affecting the behaviour of the animal as well. Actually, I think that dogs are probably the best example for this. Even better examples, though, are life forms with smaller lifespans. Humans are not really suitable for observing evolution because of our long lifespan and we can't really take humans to isolate them and let them live as live experiments. But even without that, anyone can see some of our evolved traits; the afore mentioned longer lifespan, height and, something I didn't mention before, our intelligence. No matter what people say about "new generations", humans are, on average, becoming more intelligent with every new generation. And not because of magical space dust or giant omnipotent man in the sun.
Still, I'm interested in what you would consider to be an "evolution of a human being". Do we need to get extra limbs, extra brains? Special powers? Lose something we don't need? Become evidently smarter, evidently prettier, stronger, better? I'm just interested in what people would approve of as being the evolution of the human kind.

The Theory of evolution still requires an impossible miracle to have occurred, and in my mind that makes it a belief more than a fact. It won't be factual until we can go back in time and see the big bang happen, or in 10-100 million years if we still have documented history and can compare our 'evolved' selves to those of old.
The big bang states that matter created itself from nothing, matterless energy was formed from nothingness, and the entire universe was the result... also that life was the result of nothingness, and that giant rocks colliding with each other somehow produces life.
Go outside and bang two rocks together, you could do it for the rest of your life and you wouldn't create a new form of life... hell... take a spaceship to outerspace and try to make it authentic if you want... you still won't get life from that... just a lot of destruction (especially on the planetary scale)
Impossible miracle? Miracle, maybe, but impossible? No, obviously, because we are here with means to observe evolution. Still, neither you nor me are biologists that dedicated their lives to this subject, so neither of us can say "All those people that
did dedicate their lives to this matter are WRONG and they missed something." Logics tell me that such complex matter cannot be explained in a few sentences or on an online encyclopaedia or that we actually have to witness something in person to know it happened. Can anyone really "witness" the eruption of Vesuvius in 79 AD and say that it really happened? No, not at all. But we have an enormous amount of evidence, such as historical records and, most importantly,
cities buried in volcanic ash. We haven't seen it and we never will, but we have indisputable evidence of this event. Evolution, however, is not just ONE event; it's a process, lasting for millions of years, a process that
still lasts and that will go on on working after humanity is long gone. We can't observe it as we could observe the eruption of a volcano. It's not an event set in time that you can just look at once and see "Ah yes, evolution just happened". And we most certainly don't have to go back in time to see our ancestors because we can already see them when we dig out their bones. What do you think anthropology and archaeology are for? And paleonthology, paleozoology (well, paleobiology in general) for that matter too. We don't need to see real dinosaurs walking around to know they existed, we have an indisputable amount of evidence for their existence (and their evolution), despite nobody saw them alive (or saw them evolving). I suppose there are still certain questions about evolution, but that does not mean evolution is not true; it just means that we have yet to develop a way to understand certain things about it. So far, evolution is very well documented and explained and can be taken for a fact, but still has minor thing that need to be attended. What else do people want? A video of a life form evolving? Well, that ain't happening (not any time soon, at least).
And smashing two rocks together is not how live started. There needs to be a delicate balance of various factors for life to appear, that's why there was no life when Mars was created or when Mercury was created. It appeared only on Earth. Not because of smashing rocks, rocks smashed in the entire solar system. But the origin of life is not a part of studying evolution. That's abiogenesis.

I've always found it funny that evolution is supposed to take millions of years, conveniently large amount of time, no? When a human being can develop from nothing more than small proteins and nutrients into a 6ft tall mass of flesh in a matter of 20 years.
Surely after the couple thousand years of recorded history we could have evolved by now at least at a small level.
Read into this however you want: think i'm religious or creationist or something.
The truth is I know that one thing throughout our entire history has remained true..
People have always thought that their age was the modern age and that their 'science' was 100% correct and "infallible".
Entire civilizations have risen and fallen thinking that the world could not improve any more than it had.
We think that today, just because we have the power of electricity (really, the power source behind all of our 'improvements') that we're special and that we have it all correct.
We're wrong.
Everything is still a theory, and it's all based on the limitations of the incorrect human mind, biased and self-interested, it doesn't surprise me in the least that there are men that can think themselves their own creator.
Regardless it doesn't matter, because whether or not science/the theory of evolution is all correct and all true, it is leading into a bad end for humanity, and those who think it will be used for the greater good of all are sadly mistaken... the thing you cling to with all your hopes and dreams will one day destroy millions, possibly billions of lives.
Science, power and the human ego.
Evolution does not "behave" "conveniently" for us. Evolution just
is, whether we are here or not. Evolution was happening for hundreds of millions of years before humans appeared on Earth. And what do you mean by developing "from nothing more than small proteins and nutrients into a 6ft tall mass of flesh in a matter of 20 years"? As in, in 20 years, a human goes from being an egg and a single sperm to being a fully developed human being? What's that have to do with evolution? Evolution is a process that needs thousands, millions of years, depending on what's happening; to go from a simple life form to a human being, yes, it needs millions of years. To make humans taller or smarter? A few thousands.
Now, I don't know how to make this sound any prettier, but you need to get to know a thing or two about the world. Telling someone "You need education" may sound like mocking, but I find it to be a delightful truth for all humans on this planet, and something you apparently agree on; humans don't know everything and it is doubtful that we ever will. However, the more we know, the stronger we are and the better we are. Yes, some people will use it for evil deeds, just as some people use ignorance for evil deeds. Should we stop exploring the world around us because of that? No. Ignorance is not a bliss. Ignorance is the darkness where the abilities of a human being, evolved after thousands, millions of years, are left unexplored and unused. It is through knowledge that we realized that our actions are hurting Earth's ecosystem and our fellow humans and it is through ignorance that we've killed and destroyed million, possibly billions of lives. Was it science and knowledge that killed people in the Crusades, or burned "witches" or created the Holocaust? No, it was ignorance.
I agree that we don't know everything and all scientists agree too. It is a sign of a simple mind when someone believes there's nothing left to learn, and people knew that since the dawn of time. I'll give you a quote from Seneca, which was printed at the beginning of one of my Physics textbooks for high school:
"The time will come when diligent research over periods will bring to light things which now lie hidden... Many discoveries are reserved for ages still to come, when memories of us will have been effaced. Our universe is a sorry little affair unless it has something for every age to investigate. Nature does not reveal her mysteries once and for all."
- Seneca (Opera: Naturalium Quaestionum Libri)
Wise men and women have known, since recorded history (and probably before that too), that no man will ever know all that is. However, we currently live in time where we have the biggest amount of knowledge at our disposal, more than ever in history. What is even more important, never before in history have more men and women been able to freely get all that knowledge for themselves. Never before were there so many schools and so many opportunities to learn. Never before was there
Internet, a place where anyone can reach any type of knowledge in a matter of seconds (it's not the best way to learn, but it's a very good start, especially if it has a lot of sources. So Wikipedia is not always something to be entirely dismissed). Yes, we don't know everything. But we have more knowledge and more possibilities for learning now than ever before in the history of mankind.
People really need to stop looking at science as if it is a horrible monster. And I tell you this because I was once in your position. Only now do I realise that I was far too young and lacking in far too much knowledge. As soon as I opened my mind and started exploring the world around me, I realised that science is not a monster to be feared; ignorance is. Indifference is. Simple-mindedness is. Refusing to broaden your horizons, refusing to stand up and just TAKE all the possibilities you have to learn is.
You can make an educated guess that all questions you currently have about evolution have already been answered by scientists, after many decades of research, observation, testing, accumulating and documenting of huge amounts of data and knowledge. If you have questions about evolution that you can't find answers for, then you might just be a revolutionary thinker who thought of something before everyone else and I'd urge you to go and study the subject, especially if you have a major interest in it. Maybe you'll stumble upon your answer along the way and maybe you end being the one who discovers it. The cure for almost any problem is education, but only if you let yourself use it.
Note: I may be wrong about some things, but hey, it's nothing that some good old education can't fix.
