Thank you for finally addressing the argument.

“not nothing” is fine.

Step 1 is stated as a necessary condition of My existence - i.e., that I
remain self-identical throughout all my perceptions. Denying that would
be denying an identical referent for the identical first person pronoun
that I use to refer to myself at any point in my life (I was born, I am
now X, I will die). So step two concludes that knowing my existence
implies knowing that there is some identity throughout everything about
me that changes.

Yes, the referent for both “I” and “my” is assumed to be the same. As
which reality type, the argument works whether it is phenomenal or
metaphenomenal. If it’s phenomenal, then there is no evidence that there
is any phenomenon that remains identical throughout my whole life. If
it’s metaphenomenal, there is similarly no evidence that there is any
metaphenomenon that remains identical throughout my whole life.

First, the argument above isn’t that I know it is not the case that I
am. The argument is that I don’t know that I am (i.e., a skeptical
conclusion about knowing that I exist). You have made this same
misrepresentation several times now. Please get it right next time.
Secondly, Hume’s argues that there is no evidence for EITHER my
phenomenal or metaphenomenal identity. So his argument isn’t limited to
your I-3.

We’ll get to Heidegger later.

I am limiting it to evidence based logical deduction.

Misrepresentation #1. Scientific procedure is not limited to argument by
direct perception. Most scientific conclusions (e.g., about stars or
atoms or dinosaurs) are deduced from the perception of something else,
through a series of argumentative steps. All I said was “evidence,”
which can mean either direct perception or deduction from direct
perception of something else.

Misrepresentation #2. The argument is not limited to direct observation
of something unchanging within perceptions, but also includes proposed
deductions of something unchanging.

Misrepresentation #3. The report is not limited to “not having perceived
anything unchanging,” but includes proposed deductions from changing
perceptions.

Misrepresentation #4. The conclusion isn’t that “there is no I-3,” but
that I cannot know there is any I-3.

Considering four significant back-to-back misrepresentations of the
argument, you have a strange definition of “certainly”.

Then please describe this “experience” (your word) of reflective
self-awareness to which you refer, and precisely what in that experience
indicates an identity within your changing perceptions.
