What I believe (the world is flat) doesn't define what is real (spoiler alert: it is a sphere).
We must dip our toes into the pool of philosophy and ask "What is real?" More specifically, "What is the nature of reality?" Philosophers call that ontology. It is an important question.
Is there cosmic, spiritual energy we can tap into? Are demons flying around trying to destroy us? Or is this still our Father's world? This is one of five truths you didn't know you need to know.
