I'm not inclined to argue too hard in favor of God guided evolution, but I don't think you've demonstrated that such a belief is "very irrational". At worst, it's not provable, but it's not disprovable.

And the next step is to realize that things that are neither provable nor disprovable do not have any effect on the universe we live in, and thus can safely be ignored and forgotten.
