Sure. To be clear, I’m an engineer and an atheist so I don’t mean it to attack either Athiesm or science by any means.

To start with, we cannot get true knowledge of the world outside ourselves by sensory perception alone. Rather, the way we interpret our sensory inputs is by applying it to some metaphysical framework of how we believe the outside world works.

As a small example, Descartes famously brought up analogy of a melting candle. A totally naive person being born into existence would see melted wax and hardened wax as two different substances. Sensory perception alone would lie to this person. Only by interpreting it through this metaphysical framework do we come to the conclusion that melted wax and hardened wax are the same thing at different temperatures.

This extends to deeper concepts that we can’t directly explain by our experience alone. At some point we stop using our own direct experience and expand our metaphysical framework using something else.

The thing that springs from that “something else” is religion, and in many instances it doesn’t necessarily encompass a concept of divinity or worship. In abrahamic religions it is the Judeo-Christian god. In Daoism it’s the belief in the Dao, an unexplainable force tied to the events of the natural world. In science it’s belief in the scientific method’s ability to produce objective truth with sufficient cooperation and experimentation. They’re all models of the outside world that stem from something beyond a single individuals sensory perception.
