The Atlantic Conference is a not-for-profit company whose sole aim is to further the study of early trans-Atlantic contact. This year, the planning is being handled by Rick Osmon and Steve St. Clair.
Since the 1933 discovery of a flint spearhead unearthed at Clovis, New Mexico, scientists, academics, and just about everyone else became entrenched in the idea that North Americans arrived on this continent exclusively via the Bering Strait land bridge.
The mammoth skeleton that lay beside the Clovis point was carbon-dated to 11,500 years ago, and there seemed to be no other find that pointed to older human habitation in North America. This theory became so accepted that archaeologists stopped looking for older artifacts.
