Logical Challenge for an Atheist
Here's a logical challenge:
First, an introduction: From the perspective of logic and philosophy, the only position that can be taken without evidence is agnosticism. That is to say, agnosticism with an open mind is the only default position.
The atheists on this site essentially are arguing from this form categorical proposition: God is one who does not exist.
What proofs can you offer for this proposition?
(Remember, that in logic, an argument against a position is never an argument for a position)
(Also remember, that in logic, a syllogism is only true if its constituent parts are true - and provable through inductive reasoning)
