The complexity of God

Hello Rabbi, until now I have held the assumption that the world is very complex, which indicates a more complex planner, and such a complex planner would not create such a world without a reason, which leads me to the necessity of the existence of religion (hence, and Judaism is a different, less related move).
In a conversation with someone, a claim was made that God could also be very limited in his abilities, and could only create “raw” things, and that he might not even reach the singular point and activate it. I replied that even if he only created that, he would still have to create the potential complexity. His response was that in theory it sounded correct, but as proof he brought up the idea of ​​AI, which he claims was initially developed by humans but has developed and perfected itself to places that programmers could not have anticipated, and it is not impossible that it will give initial impetus to the universe, like the programmers who gave initial impetus to AI, and from there everything will run on its own, which means that God can be uncomplicated, and there is no need for religion either. I had no answer for that.
What can be said in response to this, or are my perception and actions wrong from the start?
Thank you very much.
