And if don't agree that there is a requirement for a first cause?
then what?
We are at an impasse once again
You're running from your entire argument that the first cause is this thing called spirit and that the only things that can exist in this universe or outside this universe are matter energy and spirit.
yet you have no way of knowing what if anything exists outside this universe because we are incapable of seeing far enough back in time to know what happened before this universe came to be.
So i can just as easily say the universe caused itself as you can say something else caused the universe
and once again we are at an impasse.
You want to lead this int an Ah Hah you have to admit god exists and you can't and that bugs the shit out of you.
