What was the primary goal of European colonists when they set foot in America?

I understand that this problem is the primary goal of European colonists to set foot in America; Then you have to ask the Europeans the purpose of their first visit to the United States, otherwise you can't use the word set foot on many times.

For Columbus, the first European colonial representative, it was a personal exploration, which proved that the earth was round, and India could be reached from the west, and religion was promoted. Therefore, it is important to note that European colonists were not afraid of Britain when they first arrived in America, when Britain was still a hair! Nor plundered wealth. At that time, although the Spanish royal family expected Columbus to bring back wealth from America (they thought it was India), Columbus did not do so, which was the main reason for being left out later.
