I am the only conscious human on this world. You however could easily be compared to as a non-playable-character in a video game. You have no sense of self, no will, ect. Your animated to behave like me, and prepare responses like "I think, therefore I am". It's all just an act, stop pretending.

Ok, all jokes aside. How do I know if this really isn't true? I coud never be you. Or better yet how do you know I'm not an npc and your the only consciousness playing this "massive game"?
