America got "nuked" in 12,500 BC! In 12,500 BC North America fossil records show powerful nearby supernova or cosmic ray jet hit during reduced magnetic polarity?  Traditional history tells us that the first people who entered North America came across the Bering Sea, from Asia, and migrated South to the continent around 12,000 BC. But this date has often puzzled archaeologists who place the migration in South America to a much earlier date -- around 32,000 BC. How can these two dates be so far apart?Edit

Since no traces of the Homo habilis or the Homo erectus could be found in America, Archeologists conclude that America must have been settled by the Homo sapiens sapiens about 12,000 years ago There are 4 main migration-hypothesies: A) People came via the BERING SRAIT from Sibiria to Alaska;B) People from SIBIRIA crossed the Northern Pacific and landed on the American coast;C) People from POLYNESIA crossed the Pacific Ocean and landed either in Northern or Southern America;D) People from EUROPE crossed either the Atlantic Ocean or came via Russia and Sibiria to America. Recently, scientists have started questioning the methods used to date artifacts and strata in the earth that support this early (12000 BC) date. The traditional method, Carbon-14, has been used with confidence since it is based on well known principles of physics. But while the method may be well understood, certain natural phenomenon may have interfered with the sites in the Northern Hemiphere and caused the readings of Carbon 14 to be inaccurate. Specifically, scientists now believe that a nuclear explosion or a similar event could have changed the chemistry of Carbon 14 thousands of years ago, throwing off the real dates by thousands of years! A pattern of unusually young radiocarbon dates in the Northeast has been noted by researchers and this indicates that the entire Great Lakes region (and beyond) was subjected to particle bombardment and a catastrophic nuclear irradiation that produced secondary thermal neutrons from cosmic ray interactions. The neutrons produced unusually large quantities of 239 Pu and substantially altered the natural uranium abundance ratios ( 235 U/238 U) in artifacts and in other exposed materials including cherts, sediments, and the entire landscape. These neutrons necessarily transmuted residual nitrogen (14 N) in the dated charcoals to radiocarbon, thus explaining the anomalous dates. The evidence from dated materialsScientists investigated a cluster of especially young radiocarbon dates concentrated in the north-central area of North America. For example, at the Gainey site in Michigan a 2880 yr BC radio-carbon date was reported, while the thermoluminescence date (a different dating test) for that same site is 12,400 BC! Other anomalous dates were found at Leavitt in Michigan, Zander and Thedford in Ontario, Potts in New York, Alton in Indiana, and Grant Lake in Nunavut. The Grant Lake Paleoindian site is most remarkable because its 160 BC age is fairly young, while adjacent and deeper samples give ages of 1480 to 3620 BC.
