Two fundamental axioms in physics are the law of conservation—that energy cannot be created out of nothing—and the principle of causality. This inevitably leads to the ultimate question: Where did everything come from?

Consider the causal chain:

• Effect: The physical universe > Cause: The Big Bang

• Effect: The Big Bang > Cause: The initial Singularity

• Effect: The Singularity > Cause: ?

Science can trace the universe back to the initial singularity, but it cannot explain what caused the singularity itself, nor what preceded time. Because physics reaches an absolute standstill at this boundary, science alone cannot resolve the ultimate question of existence. It is precisely at this uncaused first cause that I find my reason to believe in God—the Supreme Being and Creator of all things.
