Question

With God’s help
 
Good evening, 
Greetings and blessings,
 
In the cosmological proof in the notebooks, in order to avoid the problem of infinity, you reformulated the proof roughly like this: everything with which we are familiar and about which we have experience has a cause for its coming into being, and that about which we have no knowledge does not necessarily have a cause. And in fact, the first reality that has no cause—that we can define as God. (I hope I quoted you accurately from memory.)
 
The question that perhaps needs further sharpening is why the world itself, with all its components, is considered something about which we have experience. After all, we have never actually seen dust or water come into being. As I understand it, this is at most an intuitive assumption on our part, and therefore perhaps one could argue, as Gersonides argued, that the material of the world is eternal, since seemingly we have no evidence from our personal experience to contradict this.
I would be happy for an explanation on this matter.
 
Thank you very much,
