Question

I just now finished the proof from morality in your interesting book The First Existent.
I wasn’t able to understand why you assume that if humanity exists, there must be someone who created “higher-level rules” that would preserve it on a human and moral level. (Your proof from morality.)
Suppose the world was created by chance; over trillions of years mutations and different species replicated, and now there are human beings of our kind. Human beings develop moral rules as part of the moral progress of the world and out of the understanding that it is better to live alongside one another. So what is the connection to the fact that in Germany, through democracy, they reached such moral depravity? So what? Why does that mean there must be a “categorical imperative” of an intelligent God? It could be that in another 2,000 years human beings won’t believe their ears when they hear that people like them used to feed on the meat of cows and chickens, just as we can’t believe that perhaps (for the sake of a hypothetical example) 20,000 years ago human beings ate other human beings (everyone, not just cannibals).
Just as a person has a survival need (and a zebra does too), so too human society has a need to produce moral rules, and that is a natural need. And overall, just as Kant felt a need to build a “winning model,” religions did this naturally through the gods they invented (the easiest solution).
Of course I don’t actually think that, Heaven forbid; I’m writing it this way only for the sake of sharpening the question.
Thank you very much, and have a good week.
