The Physicist and His False God

I'm the last remaining physicist, studying "pseudoscience" in an apocalyptic world where belief is everything. My community was cornered by a "magic stick" who could create water out of thin air. Everyone was worshiping him, and I, in public, used a lever to lift the boulder that he could not move. I told him this is called Newton's law. In his horrified eyes, I saw a spark of truth. Now, the person whom the survivors kneel to has become me. But I knew there was big trouble - they were beginning to believe that I was the only "god." In the distance, the followers of that "god stick" were waving the flames of belief, trying to burn me and my laws together.
