There is a popular myth that says that we all have a double or doppelganger somewhere in the world. It sounds crazy, but the chances of this happening are high and these celebrities are proof of that.
If you wonder what is the reason for having a twin of another mother, the reason is that the genes that make up a human face are many, but we are also many humans, so some genetic combinations end up being repeated among people, more if they belong to the same ethnic group or have a kinship, even if it is distant.
