The body I inhabit is descended from apes. But what am "I"?
Are you the body, or are you the mind?
I am a construct created by a brain, bootstrapped into existence using memories that this body has collected.
But "I" can only experience what the brain running my simulation feeds me. My perspective is only based on sensors that collect data about reality. I am not directly experiencing Reality (capital R - meaning "the REAL"), I am experiencing a simulated reality.

How do you know this is true?
When you see an object, you know it exists, but the "seeing of the object" is not the object. The image in your mind only exists for you, and it only attempts to model reality, it is a poor substitute for the Real.
