Any representation of a thing is not the thing itself.
“I think I am”...are merely words explaining a representation of that which I think I am... and therefore, because it is merely a representation, whatever description that follows is not you.
Unpack this further and we will discover that “I am all things at different moments in time and space”. Therefore it stands to reason, if I am all things, I am in fact no certain or specific thing. And to unpack that even further, if I am no specific thing, I am therefore no thing. “I am nobody.” I always have been, and always shall be nobody.
Upon realization of this knowledge you will become free from attachment. Period. Once free from attachment, the being is left to enjoy moments of time by witnessing each moment pass by. The moment is merely a moment. It is not a representation of the being, nor is it something in or of itself. It too is nothing; and therefore it too is also a potential something, hence it too is everything (it has the capability to produce moments made up of every thing). Each moment is a nothing, and therefore an everything. Yet, like the thing called me, each moment is neither permanent nor real (it is not real because one moment it exists, and the next it does not. if it does not exist in the next moment, it cannot be classified as ‘real’; it is non-existent.
The ultimate answer to who am I?
I am Nobody, which is experiencing never ending moments of being a representation of something. A microcosm that is in a constant state of flux. I am THAT which witnesses the macrocosm, which in itself is in a constant state of flux. I am nobody witnessing the potential of everything that is created from the space of nothingness.
