Who are anyone?

Just Google for "Who am I". I found "Everything". Am  I really "Everything"? - just asked myself. Am I, really? Could I? Not as a permanent state... Maybe, if I sum "all the partial am for every single day I lived". But do I want to be Everything? What's left? Maybe if I just create something new, I'll just drop the "Everythingy" thing. If at least Google didn't find out...
