Why do Caucasians live on all continents?

Europeans, or people of the Caucasian race, in the Middle Ages created states that technologically bypassed countries in all other regions of the world. This made it possible for them to make rather long sea voyages, as a result of which all other continents were discovered (except for Africa, it was known since Antiquity). Europeans quickly began to establish colonies on new continents, and a huge number of immigrants left to live there. During this colonization, Caucasians live on all continents.
