For the invisible things of him from the creation of the world are clearly seen,
being understood by the things that are made,
even his eternal power and Godhead;
so that they are without excuse:
Romans 1:20
"The cause of the universe must have been non-material because if the cause was material / natural, it would be subject to the same laws of decay as the universe. That means it would have to have had a beginning itself and you have the same problem as cycles of births and deaths of universes.
So the cause of the universe’s beginning must have been super-natural, i.e. non-material or spirit—a cause outside of space-matter-time.
Such a cause would not be subject to the law of decay and so would not have a beginning. That is, the cause had to be eternal spirit."
