![“[ When a religious couple wrote to Sagan about fulfilled prophecies, he wrote back in May 1996 :] If ‘fulfilled prophecy’ is your criterion, why do you not believe in materialistic science, which has an unparalleled record of fulfilled prophecy? Consider, for example, eclipses.” quote by Carl Sagan](https://sms4smile.com/quotes/img-quotes/875/carl-sagan-160_belief_when-a-religious-couple-wrote-to-sagan-a_25095.jpg)
