You are over exaggerating Giz.
We humans don't know not even 20 percent of it to begin with.
Humans tend to make rules for themselves - they treat them as a borders that can not be crossed. Once a "border" has been created, you will follow the normal and "logic" life of the rest of the society: you will accept what the others accept, you will reject and they reject, and you will do as your rules and the society wants. When you tend to see, hear, or do something that is unnatural to the world and to the laws of nature, you will classify it as an unlogical occurance and that it would never repeat again.
The rules humans made have made the humans a more complex, but yet, lower life form then the humans of the past.
Humans of the past, and by past, I mean by millions of years, did not follow rules; they didn't create rules to follow in the first place. In another word, they didn't have limites as to what physical and mental powers they had and obtained. They were mentally and physically powerful beings of this earth.
The current human state is not at its best at all. More and more rules are being created over time - more and more borders are being set up to stop us from reaching "outside" the border.
Why do humans assume? What are the rules? Do we, humans, already, know all the rules? What are the rules? Define them? There is no definition. Overtime, the rules have accumelated to an extent that lowered the human being into what we are now; give it millions of years, and the human being will be the lowest life form on earth.
Humans will never be able to fly, in anyway, it's just not right; in another word, it's against the rules that we made ourselves! God dang it, we made the rules ourselves! Can humans fly now? Yes. In many ways: planes are the most common.
What? You mean you're telling me that the Earth is a round sphere rather than flat? You are an insane man. You are crazy, in another word: you are not following the rules we created over time.
Well, guess what, Earth is a globe, a round sphere! How could that be possible? Sorry, it is.
You mean that this little brown box can have pictures and sound coming from it representing the events in another place? You are obsecure. This is impossible. Or is it? Come now, and see the televisions and dvds and say it's impossible!'
You see that? Most rules are made upon logic. If anything "wiered" happens, even if its seen with ones own eyes, it will be classified as an "impossibility".
Humans don't know nothing.
Until people start breaking the laws, and passing the borders that they, themselves have created, the humans will discover nothing! Nothing! Sure, go ahead, make whatever you want with that nueclear bomb, but still, you'll know nothing...Go ahead, come up with the next big thing...You'll know nothing.
Nothing will happen and nothing will change until the rules are broken and the laws are denied. Nothing will alter until the bordres have been erased.
