Obligation to obey God as the first wise one

Hello Rabbi.

You wrote to me in response yesterday that the obligation to obey God's command is the first rational principle that exists among most of the world and there is no point in arguing about it.
But the very fact that there is a discussion about whether such a first intelligent being exists challenges its very existence. Have we heard of many people who challenge the first intelligent being, which is the moral imperative? Who challenge the first intelligent being, which is the principle of causality?
On the other hand, the claim that it is obligatory to obey the divine command is first understood by many.
First, by its very nature, there should be absolute consensus.

Moreover, in my opinion, this rationality is contrary to morality. The duty to obey God is slavery, and slavery is immoral. It is unthinkable that in the name of gratitude I would have to enslave myself with all my might, all my heart, and all my soul, as is required in the service of God. And it is impossible for two primary rationalities (morality and the divine command) to be contradictory.

If God had appeared to me and demanded that I keep his commandments, I would have politely refused (and if I had agreed anyway, it would have been out of fear or some other bad reason).

By the way, I saw that the option to comment was blocked in the original discussion. Is this by chance or on purpose? If it is on purpose, feel free to delete my question.

Thank you very much.
