Oh look, my eyes work. Some people's don't, but that's a malfunction of the design that works. What kind of eye do you want, man? If it's not a design up to your standards, what would be?
No, it's not up to my standards:

The human eye is proof that we were not designed (or that if we were, the designer was an idiot, hence cannot have been G-d).
What is an organic pain collector?
You are walking in one. It's the human body, from a design perspective.
Just because God CAN stop parts of His creation from hurting other parts, that doesn't mean it's in our interest to not be hurt ever.
It is not in anybody's interest that people die of AIDS or Malaria. Why did G-d create AIDS and Malaria?
If Creationism or "intelligent" design is a science, the theory should cover those questions.
Pain and dealing with pain often grows relationships with other humans and with God. No, it's not fun, but we lost the good life when Adam and Eve disobeyed.
Some of us did. Others did not. Why is G-d punishing some of us and not others?
"or the sudden coming into existence of a very complex entity like a Creator who then goes on to create lifeforms that eat each other and die of horrible diseases he also created?"
The world He created has a beginning and an end - not God. Eternal goes both ways for God. He INVENTED time. God was, is, and will be.
Why?
Is that where the "theory" ends? The smurf made everything and there is no explanation for the smurf, so don't ask?
Is that what "intelligent" design should teach people? Some smurf created imperfect beings and lots of diseases and we don't know why and cannot find out? How is that useful knowledge?
How can I verify any of it in an experiment? How can I use the knowledge to design or invent things? I can verify evolution, I can use evolution to create. What do I do with Creationism or "intelligent" design?
What if we teach some other book instead? Like the excellent Belgian comic "Spirou et Fantasio"? It also teaches us nothing. But it has pictures.
"It was always there" is not a very good explanation for something.
