A 4,000-year-old Greenland man just entered the scientific debate over the origins of prehistoric populations in the Americas. A nearly complete sequence of nuclear DNA extracted from strands of the long-dead man’s hair — the first such sequence obtained from an ancient person — highlights a previously unknown and relatively recent migration of northeastern Asians into the New World about 5,500 years ago, scientists say. An analysis of differences, or mutations, at single base pairs on the ancient Greenlander’s nuclear genome indicates that his father’s ancestors came from northeastern Siberia, report geneticist Morten Rasmussen of the Natural History Museum of Denmark in Copenhagen and his colleagues in the Feb. 11 Nature. Three modern hunter-gatherer groups in that region — the Nganasans, Koryaks and Chukchis — display a closer genetic link to the Greenland individual than do Native American groups living in cold northern areas of North America, Rasmussen says.
Oh yeah, I also added references to studies on DNA which proves that these cultures did have ancient migrations/contract with the Americas. The DNA evidence is incredibly revealing and stunning.

Why does the history of North America begin 30 000 years ago?

Let us wait for some more confirmation on this. A piece of charcoal and some rock flints (that others deem natural instead of human made) is not proof enough - it is an indication though to dig deeper and look for more of those pieces of evidence to make one's case.
