Who argues that we don't really exist just because we are made up of molecules? That doesn't make sense at all, EVERYTHING that exists is made up of molecules, that is what existence is.

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

I am very confused by these people you say argue that we don't exist. I have never heard anyone argue that.

There are people who think a machine that can produce the same outputs as or better than humans are just as good or better than humans, that we can be treated just as black boxes.

Those people frighten me.

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

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.
