Argument by design is the best argument. All others fail miserably. I am an atheist but the argument by design has some legs that can be argued. Not saying it has solid legs but legs. You can refute the argument of the eye by showing that its not all that great of a design, and has many flaws but you can still argue it shows design.
Unfortunately, the 'argument from design' fails, since the Abrahamic God Jehovah is highly-ignorant of "His" own designs in the Bible (eg the firmament, cosmology, climatology, let alone human anatomy: the role of the heart, kidneys, and the fact the brain isn't even mentioned in the Bible! etc).
So God fails in His claim of being the designer (much less an "intelligent" designer) if you compare the information offered in the Bible vs the what is known via science.
