Various questions about faith

Hello Rabbi,
I would appreciate your response/reference to the answers to these questions:
1. Do you think that saying that God has a will is a problem in that it makes God deficient?
2. The Ramchal writes that God created the world to be good. I have never understood his answer. If God wants to be good, then He will be good without all the suffering in the world. Do you accept his answer or, in light of what I argued, no.
3. I once heard in your name that God is subject to logic – where can I understand that more? It sounds strange to me that God is subject to something.
4. I also heard from you that you like Rav Kook’s answer to the question of why God created the world – because it is complete, then in any case He cannot complete Himself and He created a world that would be complete and thereby He completes Himself. Where can I read more about this explanation? It is strange to claim that God is an egoist who created the world so that it would be more complete, in my opinion…
5. The antiquity of the world – from what you know – is it clear that the world was created and not ancient?
