Philosophy and religion are not mutually inclusive, though one can certainly describe a religious belief as being a philosophical belief.

Even a scientifically inclined atheist has philosophical ideas grounding their world view. The idea that the universe exists as an objective absolute with immutable laws of nature is a metaphysical idea. The idea that nature can be observed and that reason is a valid tool for acquiring knowledge about nature is an epistemological idea. Ethics is another field of philosophy and it would be a mistake to assume a universal system of ethics that has been constant throughout all cultures across all of human history.

So while I certainly agree that there is a very common hand-wave of "look the atheists have just replaced God with a new 'god' by a different name", you don't have to focus on religion, theology and faith based belief systems to identify different categories of philosophical ideas and how they have shaped different cultures, their beliefs and behaviours throughout history.

A student of philosophy would identify the concept of "my truth" as being an idea put forward by Emmanuel Kant, for example, even though the person saying that doesn't know that that's the root of the idea that reality is subjective. Similarly, the empirically grounded scientist would be recognized as following in the footsteps of Aristotle. The pious bible thumper parroting ideas published by Plato.

The point is that philosophy is not the same thing as religion and philosophy directly shapes how people think, what they believe and therefore how they act and behave. And it's kind of uncanny how an understanding of philosophy can place historical events in context and what kinds of predictive capabilities it has when it comes to human behaviour in the aggregate.

This sounds very educated but I don't really see what it has to do with the comment you're responding to (or with AI).
