Final answer:
One's actions would depend on personal beliefs and values, while some may continue to hold their beliefs and others may change their beliefs based on the proof provided.
Step-by-step explanation:
When faced with irrefutable proof that God doesn't exist, one's actions would depend on personal beliefs and values. Some individuals may continue to hold their beliefs and practice their religion, while others may change their beliefs and adopt an atheistic perspective. Similarly, if there was irrefutable proof that God does exist, individuals may choose to strengthen their faith and religious practices or may be compelled to re-evaluate their beliefs.
