Why did English colonists consider themselves superior to Indians and Africans?

English colonists considered themselves superior to Indians and Africans because of how different their cultures were. English colonists thought that the Indians and Africans lacked traits of English civilization. Colonists migrating from Europe to the New World were coming from a place that was well established with religion, government, arts, and much more; which was far different to the Natives of the New World and the Africans. English colonists arrived to the New World to find the Native Americans clothed with leaves and had thoughts of the Indians acting with savage behavior. English colonists considered themselves superior to Africans because of the color of their skin. In the Oxford English Dictionary the word black (which English colonists referred to Africans as) meant many negative things like horrible, wicked, deadly. The word white meant pure and goodness; the exact opposite of the word black. Because of the opposite meanings between black and white, it was easy for English colonists to think they were superior to the African people in the New World. Because the skin color of the Africans were viewed as un-Elglish, the Africans were cursed in the eye of the English colonists.
