** Blind Post **
Not to take the side of the theist; but, proving a negative seems hardly feasible. It is very likely that you provided evidence of the improbability of such a being; a claim with which I would personally share that nonbelief; but hard evidence that proves the negative? Hmmm.
Say god is an "empty space" (We can't see it).
Empty spaces are defined by the walls (Example: traditions/culture/history)
A theist is saying that the empty space exists because of the walls.
A atheist (many) tell theist to prove the empty space exist
without referring to the walls that defines it. It's like they want theists to make present something that is, well, empty without referring to the actual thing that makes it exist in the first place.
Some atheist think that theist believe god is some guy floating in the sky like casper (in other words, theist making a claim [there's an empty space] without being backed up by evidence [the walls]) Theist repeatedly give atheist the walls-the text, the traditions, the culture, their experiences.
ALL of these things define god.
The issue is that theist do not separate the walls from the empty space. For example, they don't separate the bible from god.
So, in my other post I gave evidence, I just gave detailed evidence that the walls define empty space; an empty space does not exist on its own as many theist say. It is depended on something.
You used negative and positive. Theist are saying negatives exist without understanding that their negative cannot exist without the positive. Many god-religions such as Bahai go out of the way to take out the positive of their religions (traditions, rituals, dogma) so they can keep the negatives.
Again, though, with all god-believers of the western realm. You understand god by first understanding how theist define god (a feeling, connection, thought, gut, so forth). Then you see how it relates to humanity and study (psychology, place in the world, culture, etc) these are the walls/the positive.
You drop what theist say about "god existing" because god
does exist. The negatives do exist; the empty space
does exist. Just many (not all) theist can't tell the difference between a negative and a positive. They know. They aren't aliens. They are just blind to it.
Nothing wrong with that. Just take their word for it and move on.
