You have probably seen me write/talk about the fact that there is not one person 100% like any other person in the world. I mean, think about everything that makes up who we are: Our genes. The combination of all our experiences since birth, or even of past life experiences if that’s what you’re into. The beliefs or set of beliefs we have adopted throughout our lives. Then take into account the interactions with other humans, who have their own beliefs and experiences. Add the environment to this, and you have even more variety if you consider weather, food, culture, ideology, vegetation, etc. etc.
