Nature thought the flat land in that area was too flat, especially to move glaciers back and forth on the land. So over thousands of years, nature sent glaciers down across what is now Canada and now the US. These glaciers would advance...and retreat... over and over during seasons throughout the glacial period of earth. As the glaciers advanced and receded, it broke rocks down, which eventually created five very deep "basins". Each of these basins, as they formed, collected rain water and melted glacial water. Eventually, the glaciers retreated off these lands.

The basins formed by the glaciers created The Great Lakes, and are known as glacial lakes. No one built Lake Erie; nature formed or created it.
