Thousands of years ago, many of the parts of the earth were covered with glaciers, or large and thick sheets of ice. When the glaciers grew bigger, the water level would decrease; since the water level decreased, some land that was submerged grew dry and shallow. Between Siberia and Alaska, the water level depleted and the land massed together. During that time, humans were tracking large game animal herds, like the Wooly Mammoth. When they were following the prehistoric animals, some of the men/woman decided to stop and settle where they were. However, some still decided to follow the herds and settled in South America.
