The most disturbing image I saw in my life

[awty]

It's not me, it's part of me.  I am more than my nervous system.  I am my body and I am also my mind.  The fact that you are impressed by the complexity of our bodies is not a warrant for believing in a deity.  Pictures are not arguments.  Incredulity is no defense for believing in the supernatural.  You ask how can we see this and still be atheists.  It's a non-sequitur.  I'd like to ask theists how they can accept such faulty reasoning?  The racism, toxic behaviours, and killings that you lament are a result of such faulty reasoning or the failure to reason at all.  Our brains and our nervous system are wonderful things and they give us the ability to do wonderful things but when we fail to use them or use them in the wrong way we are capable of horrible things.  

We do not replicate our own creation when we create something.  There is a huge equivocation here.  When we create something new, we create it by using existing materials.  The kind of creation you are talking about is creation from nothing pre existing.  It is essentially wishing things into existence.  The two are in no way alike.  

There isn't a god.  It's a fantasy.  But if I were to find myself in from of this god he better clear his schedule because I'll have a lot to say to it and it won't be short.  

It's interesting that you ask us to use our imaginations.  I know of no other way to apprehend your god but to use my imagination.  But, there is a fundamental distinction between what is real and what is imaginary, one that is identified by the primacy of existence principle. It's a principle you unwittingly use and reject at the same time any time you make a claim about your god.  I think you should reconcile that contradiction before you go presenting arguments for your god.

It includes your brain; so it is you.
We can't runaway from it. The Nervous System needs a body to work; just like a firm needs a Manager.

Without the manager; the company would fall.
Without a Nervous System; the body would fall.

That's why a "head shot" kills you immediately.
That's why a severe trauma to the Spinal Chord immobilises you immediately.

The rest of the body is a mere resource feeding the Nervous System.

None of the systems in the body can work without the others.  They are all necessary.  If the vascular system isn't working then oxygen isn't transported to the other parts of the body and they won't work.  If the lungs stop working, the body doesn't take in oxygen for the blood to carry.  If the GI system doesn't work to transform nutrients from food into what the body needs, the body won't work.  Take out a major component and everything stops.
