From a Thomistic view:

Ontology = The study of what is.

Epistemology = The study of how we know what is.

Aquinas would posit that our sciences are the epistemological process of how we come to know God . That is, it is through our experimentation and discoveries that we come to understand the true ontology of the world. The epistemological reveals the ontological (and ultimately God is what is)

There is no God vs Science dichotomy in the Thomistic view. Since the furthering of science furthers our understanding of God.

This was the view held during most of the world. It has only been in the last century where man as intentionally sought to create a division between the two (and look where its gotten us).

The big bang was discovered by a Jesuit priest (Lemaître). The entire concept of genetics was started by a monk (Mendel). The notion of the order of the solar system was discovered by church official (Copernicus).

I do agree with your point that Philosophy is very under-rated currently. Curiously I think this age of LLM / AI is going to bring its resurgence. Because ultimately its impossible to delve deeply into the notions of consciousness without understanding its philosophical underpinnings.
