How the hell did people end up on polynesia??? 
They navigated. First, oceans have wave patterns and currents that can be felt with human tactile senses. In specific, the Polynesian navigators used
the insteps of their feet, to feel the reverberation of waves hitting land, sandbars, coral reefs and the like. They followed these waves, making note
of the star positions and wind currents as they went, until they hit land. Then they resupplied, and headed back to gather colonists for the new
island. It was hardly a fast process, with the last two Polynesian colonizations (that we know about) being in the Middle Ages or so - Rapa Nui and Ao
Te Aroa.
The Polynesians did explain all this to Captain Cook and the other navigators they came across, but in typical Colonial European style, these methods
were disregarded and the Europeans cooked up mind-numbingly dumb conjectures of the "primitives" only making landfall by total accident.
Nevermind that these "total accidents" always managed to bring a viable population of people, chickens, pigs, dogs, taro, yams... And that all the
people had a very similar language...
how did stonehenge get there?
Time, people, and log rollers, paired with river barges. Seriously, just 'cause they lived a long time ago doesn't make these people inept. Leverage
is a pretty simple concept.
how did the mayans have such advanced knowlege of the earths solar obit to construct an accurate calendar? Not only that, but how did they know
that the end of an age would occour in 2012, exactly the date when the solar system aligns with the galaxy? 
First, the solar system is ALWAYS in alignment with the galaxy. Don't try to combine astronomy with new-age stuff, someone always gets hurt. The
Mayans accomplished this
exactly the same way that other people did - They made measurements, took records, you know... math and science.
Contrary to some ideas I've seen, being brown does not preclude people from knowing how to get things done.
We have found human skeletons over 100,000 years old yet there is so much Human history unexplained, only the last 6000 years is pretty well
documented.
Actually we've found human skeletons a little over a million years old. Or dod you mean
Homo sapiens?
Only the last 6,000 years is documented (and only from certain areas) because writing did not develop until people had both time for it, and need for
it. A nomadic people has no time for devising a writing system, while a small agricultural community has little need to do so. Once that settled
community gets large and trade increases, some way to create a lasting record of debt and standards requires a writing system.
Agriculture invented only 12,000 yrs ago by the Egyptians, sorry I dont buy it! Things in my opinion seem to get wierd at the last ice age
12,000 years ago.
It's good you don't buy it, because I've never heard anyone claim that. First off, "Egypt" did not exist 12,000 years ago - Egypt as a cultural
entity arose along the lower Nile (near the Delta) some seven thousand years ago - probably in response to the introduction of Agriculture from
eastward peoples.
Agriculture itself probably dates to the Mesolithic period. Ancxient settlements such as Catal Huyuk (in the Neolithic) display well-established
agriculture, while stone-age peoples existing to the modern day (such as Papuan tribes) nevertheless have some pretty advanced agricultural
techniques. In all likelihood, agriculture arose independently among many, many people the world over, at different points. Again, our ancestors
weren't stupid, and trial and error would inevitably lead to all of them perfecting the techniques best for their climates
