There may be an index to the set {human beings}, and, if there were,
you'd be able to look up 'me' in the set. It'd probably be an object
that linked to all the other objects in the set.

The relation 'stated' links an object 'H' to a statement 'q'. p, the
proposition that a human being exists, and that human is me, stands on
its own, simply asserting this is the case. Which simply asserts that
there is some human that is 'me' - it could be lots of them, or it
might be an empty set.

The relationship stated(p,me) links the 'me' to the statement,
specifying that 'me' is part of the set of human beings qualifies it

It's different from saying 'you are', because the person making the
statement is linked to the proposition by the operator 'stated'.

You could go on to express that:

p2='∃y, y ∈ { human beings} s.t. y = you'

Then I could assert that you exist by:

me ∈ { human beings} ⋀ stated(p2,me).

To assert 'Peter' exists:

p3='∃z, z ∈ { human beings} s.t. z = Peter'


me ∈ { human beings} ⋀ stated(p3,me).

I could go on further:

P4='me = Peter'



You could then deduce, from p and p4 that I am Peter.

Of course, you'd need to consider whether things that are 'stated' are
true, or not, as a separate matter.
