> EVERYTHING that exists is made up of molecules, that is what existence is

This is a belief system which one does not have to believe in order to accept the findings of physical science.

> I know I have consciousness, and I know I am made up of molecules. I don't find that limiting or disappointing at all.

There's two things this can mean:

(1) You do genuinely believe you exist, but just that you're arising from a temporary arrangement of molecules -- essentially, all the statements that one can make about souls is true of you. In that case, you're not who I'm talking about.

(2) There is no such thing as "you", it is purely an illusion, and no legitimate subjective entities really exist.
