What was the primary goal of the european explorers in the 1500s

During the 1500's Spain and Portugal were the two big countries exploring The New World ( Now North and South America). Important Explorers include Christopher Columbus, Vasco de Gama, Francisco Vasquez 
          There are three main reasons for their exploration it is referred to as the 3G's, which are Gold, God, and Glory. Gold referring to money and any treasure that could be found. God referring to the Missionaries that went and converted many Natives to Christians. Glory referring to any fame that could be obtained by the explorers. Another reason is in search for land. This encouraged Imperialism throughout the New World which was practiced by many European Nations 

It taught people how to live a good life, but not what to believe.
