How to easily defeat any argument for God

[Acrobat]

I have evolved as a member of the human species to see. To recognize that that certain things outside of my mind are real, like the sun, the room I'm in.

I can recognize the natural facts of a babies head getting cut off, all the parts that went into the actions, the various brain states etc.. I can also recognize an objective badness, that is neither a part of my brain state, nor in any of the scientific facts surrounding this. 

We have evolved to recognize an objective non-natural/immaterial/transcedent moral reality not reducible to scientific facts, or brain states.

You have made no attempt to demonstrate such a reality that you speak of. You just jump the gun by going there without first ruling out the naturalistic explanations.

The descriptor "bad" is linked to what the act itself entails, "good" is not floating out there somewhere in the divine realm.

I've indicated that we all recognize the objective badness of x, and that this objectiviness is real and not an illusion, or something subjective. 

I've also demonstrated that this objective badness of x does not exist in any of scientific/natural facts  about x. So if the objective badness of x is true, than it badness/goodness exists as a non-natural reality/property.
