This document discusses evidence of pre-Columbian intercontinental contact, including voyages by the Vikings to North America around 1000 AD as shown by their settlement at L'Anse aux Meadows in Newfoundland, Thor Heyerdahl's 1947 Kon-Tiki expedition demonstrating that early peoples could have sailed from South America to Polynesia, and the possibility that early humans arrived in the Americas through ocean voyages rather than solely over the Bering land bridge.
