The cosmological view

1. A priori assumption that everything has a reason.
2. There is a world.
There is a reason for the world – God.
According to the first assumption, we should ask what God's reason is, but this would leave us without an explanation, and therefore we should stop at the being that is first.
And it's not the material because from experience it needs a reason.
From what I understood from the Rabbi and what I didn't understand is how one can use experience, it teaches that there needs to be a reason to cause things to move or change, but we don't have experience that there needs to be a reason for the existence of matter, so we have to assume that it is the initial cause.
(The a priori principle of causality does not prefer to exclude God any more than to exclude material existence)
If so, the argument from the laws also falls apart because there is no need for a reason for the existence of matter and the laws according to which matter operates are inseparable from it.
