you're not actually understanding what's being said
Yeah, we're not on the same page.
First, let me describe what I think thoughts are - just so you have an idea where I'm coming from. Then I'll try to respond to what you said.
I believe that thoughts and consciousness are the product of the physical brain only. Neurons, chemicals, maybe something else, but definitely physical objects. So there's a limit to your thoughts. Any thought, takes up space. And the actual arrangement of the atoms in your brain IS the thought. So if I imagine that a teapot is orbiting Mars, that's represented by some number of particular atoms arranged in a particular way inside my head. If you had the technology to arrange the atoms in a particular way, then you could change the color of the teapot from white to red, for example, and that's the thought that I would have.
(disclaimer: this is obviously very simplified, but the main point is that the physical parts are entirely responsible for thought and consciousness)
Atheism/theism can only exist by limitation of conceptualization.
Not sure what you mean exactly, but my view of thought might BE a lot more limited than yours - just arrangements of atoms. This might be what you're talking about.
Imagine right now a girl in your mind, and she says, "I'm quite a radical notion, am I not?": that girl is an idea, and that idea is saying to you "I'm quite a radical notion, am I not?": that idea is as conscious as you are.
So before I read "Imagine right now a girl in your mind" there wasn't any group of atoms in my head that were arranged into the idea of a girl. After I read it, there WAS a group of atoms arranged into this idea. So I have some number of atoms, let's call it "N", that are in my head. The idea of the girl is some other number of atoms, let's call it "M". M is MUCH smaller than N. All of the atoms, N, is what makes up my consciousness, M by itself is just a small part of N. M is not enough atoms to be "conscious" or a "person" or a "being", etc.
I'm going to guess that you don't hold the same view about what thoughts are. I think maybe this is the deeper difference.
