"神が存在しなければ彼を発明する必要があるでしょう"

Simplified Meaning:

People have always looked for a higher power to make sense of the world around them and to provide comfort during difficult times. Just like when a child believes in superheroes to feel safe and brave, adults believe in God or a higher being to find purpose and strength. If no belief in God existed, humans might create one to give themselves guidance and hope. Throughout history, different cultures have invented myths and gods to explain natural events and to bring their communities together. This way, people can stay united, feel supported, and have principles to follow in their lives. For someone facing uncertainty or searching for meaning, believing in a higher power can help them find direction and assurance.
