Is atheism self-contradictory ?

[Whateverist]

Hello everyone ,

This is my first thread on the forum, and I hope to get convincing responses to a question I stumbled upon concerning atheism.

Assuming no God can be proven by logic, how can one trust his judgment about religions/existence of god if his mind itself cannot be trusted ? How can I trust any atheist/agnostic's claim that all kinds of proofs that have been given by scholars or philosophers of religion throughout history are false ?

Therefore, rejecting belief is in itself belief that your mind possesses some kind of an absolute power that makes you distinguish between good arguments and fallacies. I don't want to talk about evolution in this thread, but since the brain is the product of random alterations of our genome, how can it be trustworthy ? 

You'll say to me that this power is simply logial reasoning, but, you see, logic is based on axioms, i.e. basic FACTS taken for granted. What are you taking for granted to refute any logical argument whatsoever ? And why do you TRUST your thinking in the first place ?

I don't know how one who is under the atheist umbrella can believe that their cognitive faculties are geared towards ascertaining truth because they believe their cognitive faculties were ultimately produced by cold and mindless natural processes.

That just never gets old, does it little buddy?  Didja cut and paste it all by yourself like a big boy?  If so I hope mom gives you a gold star in school today.
