Do you realize there are some things the CAN be proven not to exist?

Question

An object that is both a circle and a square simultaneously is a contradiction and cannot exist. We can know this purely through logic. We don't need to search the universe.

However, I CANNOT prove that a unicorn does not exist. It's description is not self-contradictory. It is a theoretically possible object.

Linz: If it's definition is self-contradictory then it cannot exist AS DESCRIBED. It might exist and be different enough from the description as to no longer be self-contradictory, but then it's no longer what you said it was. In the case of the bible, if God is redefined enough so that he's no longer self-contradictory, the bible becomes incorrect.

Answer 1

I am begin to doubt that you exist.

Answer 2

Not only can you prove things with logic, you can prove that God does not exist with logic, if a few reasonable premises are accepted. So logic is one of those things believers need to stay away from.

Personally, I find gods and goddesses useful as myth and metaphor, but I don't take them more seriously than that. And what's more, I doubt that most educated Greeks and Romans in classical times did, either. They were used to illustrate a point, usually a moral point.

P.S. There was a unicorn, maybe more than one, back in the 1970s I think it was. It was surgically altered from a goat by what's-his-first-name and Morninglory Zell. They published a calendar with pictures of it gamboling around the meadow with their daughter, a young maiden. They also showed it at ren faires and pagan gatherings.

Answer 3

The only way you can prove something doesn't exist is if you know enough about its characteristics to prove it to be self-contradictory.
