To me, this is the single most important question that could ever be asked, ever be considered and hardest one to answer.
What answer can you give that does not use words which rely on other things to define them? For example, “I am a mechanic.” No, no you are not. You work as one, you have skills as one, but if you look up the up the definition if one, I do not see you’re picture there.
“I am a mother.” No, again you are not. You are in the role of a mother but your picture does not grace the pages of the Oxford Dictionary.
“I’m a human being.” Ooooh, now we are getting close but still, how true is that statement? After the first two examples does that statement hold true.
Do you know who you are?
