Empirical science can lead to a belief in God, but it cannot fully support belief in God. Philosophy, on the other hand, provides the fundamental support for the belief in God.
The intelligent design/ “God of the gaps” arguments are limited and cannot support belief in God the way a Thomistic philosophy can provide an independent and comprehensive argument for a belief in God.
God/ the “designer” does not create the world to function naturally, only to stand apart from it. The “designer” does not intervene in an ad-hoc manner thereafter to alter nature. This would mean a flaw in God’s plan and that God is competing with His creation.
Instead, Saint Thomas Aquinas proves that first and foremost, God exists, through Aquinas’ five ways. Following from that, God in his intelligence and perfection creates the world ex nihilo; and governs it. Everything that God does is in line with his own logos. As Father Robert Barron mentions in his book, “Catholicism: A Journey to the Heart of the Faith”, God is “non-competitive” and “non-violent”. God wills everything into existence at the same time such that there is no conflict between God and nature, for He acts through the things He creates.
