Questions about the physico-theological view

Greetings to the esteemed Rabbi,
The physico-theological view in the context of evolution:
1. The Rabbi believes that reason requires that there must be a Creator after seeing complexity and design. If this is indeed the case, how can one explain, in an engineering-design sense, defects found in organisms (I did not see an explanation in "The First Manifestation"), as opposed to the claim that "there is a perfect being" (God) who has the ability to create nature that will lead to impressive results?
Here are examples of problems only in the human body:

If there is an attempt at an explanation in "God plays dice" – I would be happy.
2. In "The First Commandment" on page 268, the Rabbi believes that the laws of nature were programmed to reach the current state within 14 billion years, so this is very impressive, and if it had taken longer, it would have been even more impressive.
It doesn't work out that well for me in my thinking.
A. Since when is a long time to reach a goal evidence of good planning?
If there are two engineers who reach the exact same result, wouldn't we argue that the engineer who did it faster is also the one with better quality?
*The rabbi cannot claim that 14 billion years is the minimum time to reach the goal because he has no evidence for this.
on. From God's perspective (or one who examines the physico-theological view) – if man is the pinnacle of the purpose of all creation, why did nature have to be designed so that a huge number of species would become extinct (for example, the dinosaurs or the ancient ancestors of the whale)? Wasn't it right to design nature to act ad hoc (for the current situation)?
Does the Rabbi know a quality programmer who writes so much unnecessary code that he reaches the desired goal?
