The world had been one continent, Pangaea, but then split apart with the movement of the continental plates. It is likely that the ancient people would not have had much water to cross (though Pangaea had split before then) and could have swam/made boats out of reeds, something which there is evidence to suggest.
I've heard that they were following animal herds, and that's where the herds went. Seems like it would be awfully cold to cross the Bering Strait though. Gotta eat I guess.
Columbus's discovery of the Americas
Yes it was. At least in the Americas. Democracy is an evolutionary concept of government and has its roots in Ancient Greece.
The first European Explorer was Cristopher Columbus,that was the first recorded one, but probably many Euopeans have reached the Americas.
Because their history is not cleared
Christopher Columbus brought the first white people to the Americas. There was already Native Indians that lived here first before anyone.
The first people in the Americas were bands of hunter-gatherers.
Because they weren't there, so they have to work from ancient evidence, which isn't always clear.
The Bering Land Bridge was used by the first people who came to the Americas.
Maya Counting: The ancient Maya developed a very advanced number system. They were the first in the Americas to use the number zero. Today, people in the Americas count based on the number ten. In ancient Maya times, Maya counting was based on the number twenty.
The polynesian in record were possibly the first people to come to the Americas in about 7000 BC.
Native Americans
