More on the debate with the infidel

I was glad that the debate was published, which shows the fragility of his arguments.
However, I have thought of another approach to his claims, and I would love to hear your thoughts.
Regarding morality in the Torah: In my opinion, the Torah does deal with morality (and the commandments between a man and his fellow man are in this direction), but it is simply a matter of changing human morality over the generations. In their time, the permission of a woman of good looks was gentle and considerate compared to what was accepted. The same applies to the laws of slavery.
Regarding realistic (historical or scientific) errors in the Torah: The Torah was given to Moses in prophecy. As far as we can understand what prophecy is, it is about some kind of inner intuition and a certain state of consciousness, and of course we believe that God sent information that He wanted to reach the prophet. If so, it should not be surprising if it is based on the scientific information that was available to that prophet, even if it is erroneous. This can also explain the duplications and contradictions in the Torah.
I would appreciate your opinion.
