Ybe an atheist

[Ybe]

downbeatplumb:
There isn't a god. (prove me wrong, I am always willing to view new evidence)
So it would be illogical to believe in a god.
There is no G so I am an A.

Trying to put what you said into a logical reason:
[Assertion No G]
P1 If there is no G it would be illogical to believe in G
P2 No G
C. it is illogical

If that is not what you meant to say, then the following would not apply:
Denying the antecedent, sometimes also called inverse error or fallacy of the inverse, is a formal fallacy of inferring the inverse from the original
statement. It is committed by reasoning in the form: If P, then Q. Therefore, if not P, then not Q.
(https://en.wikipedia.org/wiki/Denying_the_antecedent)

To prove you meant to say otherwise give a logical proof.
_________________________________________________________________________________
Sounds like you think you have the ability to judge E for G.

But (using A way of thinking)
Assertion - there is no convincing/sufficient E for As being able to logically reason that.
Proof:
P1. If A's can"t give convincing/sufficient E (that As are able to logically reason), then As have no ability to judge E for G.
P2. I agree that As can't give convincing/sufficient E (that As are able to logically reason).
C. So, it is true they have no ability to judge (any E for G presented)

(by modus ponens) - rule of logic stating that if a conditional statement (“if p then q ”) is accepted, and the antecedent ( p ) holds,
then the consequent ( q ) may be inferred. (ref google search)

To prove the premises false As would have to Give me convincing/sufficient E. So far not done.
