complexity

In the SD

Good week,
You based the entire physico-theological proof on the fact that we see complexity in the world. My question is what proves complexity. Apparently, there are things in our world that are not perfect. For example, the very fact that a person can be sick supposedly proves that the body is not sophisticated enough to cure itself of any disease. There are strange people in the world with mental and physical problems. Perhaps the conclusion that the world is complex is subjective/synthetic, because we do not know of anything else that is more complex, sophisticated, precise, and complete. Even if it were to be shown, God forbid, that the world was created blindly, we would still see some minimal complexity, or alternatively, we would be able to find some complexity, and then we would say that it was created intentionally. If so, this becomes proof that has no contradiction, and as you quoted from Karl Popper (I think), any evidence without contradiction is not evidence.

I would appreciate your response or a reference to what you wrote on the subject.
