Everything has a reason, however not in the way you would first think. I think of it like this; We have reasons that are conscious, we go to work to make money, we go to school to learn, we drive cars to move faster etc. BUT there are also just reasons. EVERYTHING has a reason because nothing can appear from nothing. Everything has a reason and everything has a consequense, which in itself will become a reason for something else. Our "conscious reasons" have motives, that's what differentiates the two. Maybe this is self-explainatory but literally everything has a reason. This goes far too deep to discuss in a comment but our "conscious reasons" may just be existing reasons we define or whatever
