Ybe an atheist

[Ybe]

Ybe's own statements:   
[Assertion No G]   (We can assume that "G" means "god" -...
P1 If there is no G it would be illogical to believe in G         ABSOLUTELY TRUE!  BRAVO!     
P2 No G                 Woopsie, here is where you slide for a lot of folks.  The first premise started with IF, junior.   
C. it is illogical        What is illogical? (YB: see below same color)

Wow, twice in row!

That argument was a formulation of downbeatplumb's  statement.

For the conclusion (which is the second part of P1) to be true, both premises would have to be true.
 (if that is THEIR argument)

Now  all  an A would have to do is validate P2  (prove no G).

UH OH  any evidence/proof an A would try to give someone can say:
1. That is unconvincing/sufficient evidence.
2. "Or" Perhaps there is some evidence you missed.

Lucky for you, this thread isn't about that, it is about seeing if As have a rational logical reason for being an A.
Unfortunately, as you have continued to show, we need to hear from someone else who might be able to represent the As better.

No offense, I know you are trying, but you need a little help. I would be glad to help you formulate any argument if you give something more than definitions.  Usually Definitions are presented first then an argument:
A = one who lacks belief in g(s) (would be a definition)
X = reason
If A then x
A
so x

Or
If A then x
not x
so not A

(Just remember if you put the  A definition as the reason that would be like saying)
If B is true, it will be not be written in the B
It is written in the B
So B is true
(Considered a circular argument)
