Because I know that the universe I live in operates according to the laws of physics, not the laws of gods.

[It sounds so cold and clinical, that worldview. No gods or spirits, just scientific evidence and, in the last several centuries, mathematics.]

I know that the stars I can see from home don't appear as they do because of anything other than happenstance and, once off of Earth, their appearances change altogether. And the moon? Nothing more than a lifeless satellite that was caught in Earth's orbit early in the planet's formation.
