It should also point out given several Atheist positions. Some define reason in different ways ie Rationalist argue reason is that which is reasonable that which is against their position. Empiricist would see it as that which is observed or can be known by the five senses. And Nihilist would really see no point in its use though they live their life as though its real. So they have a problem giving an account for it.

So there is a problem they need something outside of themselves to account for it. Now of course the reason atheists are rational is cause of God's moral law and being created in his image (Genesis 1:26; Romans 1).
