I have a class in philosophy. My mind always floats while I'm in class.. I usually think random things when I'm in class..then that time.. I'm thinking of why all people looks different.. there isn't anyone that looks exactly the same. I was just thinking that in my mind.. then I was surprised my professor suddenly opened that topic.. and he said god made us all unique.. then I started thinking of who made the world and the universe? if god made it then who made god.. then who made the creator of god. then who made the very first creator. then my professor again discussed this topic.. I'm like "wtf I was just thinking that". but he didn't answer the question. he just make our mind go round and round..
