About the God of religion.

Hello,
The Jewish idea of ​​sanctifying natural matter is illusory.
The use of animal skin and its wool as clothing on our bodies and for framing our homes, and in fact, trying to combine the spirituality of religion with physiology, seems to me to be delusional. (It is indeed a brilliant idea!). After all, there is no physiological difference between a person who wears tefillin and a person who does not, and there is no city, including the people who live in it, that is different, and it depends on whether there is intermarriage in the city or not.
To claim that religion and the physical are not dependent, but rather, God created the world, and us, so we must have a role. And the only one who can determine the role is the God of religion. And indeed, he has set physical rules and commandments for us. But there is no spirituality in the physical itself.
This is an absurd claim and I will explain why.
God created the world and people in it. And indeed, we are not here for nothing. Our role is to know our Creator and, in doing so, to be aware of gratitude and acknowledgment. To claim that God wants to test us whether we truly recognize Him and are so prepared to be grateful by keeping His commandments is childish. Is this the God of the ego?!
It is also understandable why there is a God of morality. Because there is a moral obligation to continue to maintain the world in the best possible way so that the recognition of its creatures continues. (I am not talking about the case of human suffering, which comes largely from human choice.)
This is still puzzling, but at least less bizarre.
I would appreciate a response.
