She asked when the world was created.

I was asked a question, and I don’t know the answer.
It is explained in the Ramchal through the Name that “God created the world when He ascended in His will.”
The question is, what is meant in this case by “at the time.” After all, God is eternal. And one must ask, why didn’t this occur to him before?
On the other hand, before that there was no concept of time. So it is not divided into “before” and “after.”
Therefore, if one asks “when” did his will arise, the answer will be “there is no such question.”
Although, this seemingly leads to the thought that the will arose immediately with the “beginning” of God’s existence. And this is not appropriate.
Ostensibly, this leads to a kind of Spinoza-like assumption, that the reality of God and the reality of the world are parallel things. And that is also problematic.
As for me, it’s clear to me that this question is generally “what’s forward and what’s backward,” and our minds don’t grasp these things. But the Baal Tshuva I’m treating has a hard time accepting that.
What is the answer? And what should be answered?
