Argument for the existence of God from the existence of immaterial souls

[Matteo97]

There is a famous argument, endorsed by many catholic philosophers (St. Alphonse Liguori to name one) which aims to prove the existence of God from the existence of (human) immaterial souls. I understand how to rule out the possibility of the creation of immaterial souls from matter (by principle of proportionate causality) however, I don't understand how to rule out the possibility of an infinite regress of immaterial souls causing the existence of another or the possibility of a non-divine immaterial soul existing from eternity.

IMHO this topic needs to be moved to the Debate Table or Catholic Q and A

I'm sorry, I've put it in the wrong section.
