Faith cannot be filed under either science or superstition. It is a philosophy of life and existence. Stoicism is a well-known philosophy. When speaking to a stoic about his/her philosophy, would you begin with, "We live in a universe with trillions of galaxies with each one of those galaxies containing hundreds of billions of suns and innumerable planets and moons. Our universe is billions of years old, so how many life forms could potentially be out there?"
My grandmother married an atheist. So did I. Family discussions on faith and atheism have been common. Consider, these comments and conclusions were presented to me by atheists, a couple of points they gave me that I, too, thought made sense, so I didn't accuse these atheists of being shallow or condescending. However, if your assessment differs, why not present something you consider to be thoughtful and intuitive?
