Here's a quiz in which you answer questions about God. If you answer inconsistently, you take a hit.
I got two questions wrong, although I can explain why I disagree. I agreed with the following statement: "As long as there are no compelling arguments or evidence that show that God does not exist, atheism is a matter of faith, not rationality."
You see, I define atheism as the view that God does not exist (either probably or definitely). I know, I know, we can quibble about definitions all day. But that is my definition. Now, I think that in the absence of positive evidence for God, one can justifiably disbelieve in God because of Occam's razor (the simplest explanation is most probably correct) because God not existing is simpler than God existing. If the Occam's razor argument were somehow disproven (and there were no good arguments for or against God's existence) then we would be stuck with agnosticism. Not believing in something is a matter of faith if you have no reason to disbelieve it. However, in many cases, when there does not seem to be any positive or negative evidence/arguments for or against some hypothesis, we often forget that Occam's razor is the only reason we can disbelieve something in the absence of positive evidence.
Here's the other one I got wrong: "You say that God does not have the freedom and power to do impossible things such as create square circles, but in an earlier answer you said that any being which it is right to call God must be free and have the power to do anything. So, on your view, God is not free and does not have the power to do what is impossible. This requires that you accept - in common with most theologians, but contrary to your earlier answer - that God's freedom and power are not unbounded. He does not have the freedom and power to do literally anything."
In my view, illogical actions (like creating a square circle) are not actions at all, but merely words that purport to describe an action but do not in fact describe an action. So a being can be omnipotent without being able to perform illogical actions (which are not actions at all).
