Theists: What is the most compelling argument you have heard for Atheism?

[Jackie]

The problem with an all powerful God is that if infinite regress. If God is already infinitely complex, then he would need his own creator even more complex, and that creator would need one more complex.

That is nonsensical from the start - I think that you should re-think it.

Keep that in mind because you already agreed with me that "fine tuning" does not point to one god claim over another. If you accept that Allah or Bramha do not exist and do not fill in the gap as a starting point, why would yours be immune to the same problem?

If you want to claim that God didn't need a prime mover, why would the universe itself need one? Seems less of a problem without a God than it would be with one. 

The universe does not need a cognition to start it anymore than Poseidon is needed to explain the start of a hurricane.

I think you are mixing a number of different arguments, because you are not making sense.  Perhaps you can clarify, or should deal with one thing at a time first.

Your inability to follow my argument is your baggage. 

WHY is a very valid question, your refusal to answer it is the problem. I am not mixing anything. You are the one who not only swallowed one particular book of myth, on top of that you swallowed pseudo science after the fact because you have to swallow more lies to prop up the original one you fell for. And you still insist on clinging to this after agreeing with me that "fine tuning" doesn't point to anyone's claim. 

Now again, WHY is it you swallow your own book, swallow pseudo science after the fact to prop up the original lie, but rightfully would not buy it if someone with another holy writing and another god claim argued the same thing? Why are you so scared of being wrong? Do you honestly think there is a cosmic Big Brother watching your every move willing to squash you like a bug if you dissent? If you do, I feel sorry for you.
