Exactly that, intelligent design is a cope mechanism slipped into a very weak argument, to try and save the fact that the existence of god is, indeed, a logical impossibility.
For the christian god in particular, you don't even need to use arguments from general logic, as the bible already does a great job to show how that religion as a whole is a collection of contradictions.

Regarding @DecBytes 's comment, no, the absence of god doesn't condone the absence of moral rules, as moral rules are universal and deductively derived from logic, god is not necessary and actually adversarial in establishing a moral set of rules.

Finally, the whole set of universal moral rules can be reduced to one: respect property rights.
